# Installing Bugzilla

## Installation

If you just want to use Bugzilla, you do not need to install it. None of this chapter is relevant to you. Ask your Bugzilla administrator for the URL to access it from your web browser.

The Bugzilla server software is usually installed on Linux or Solaris. If you are installing on another OS, check before you start your installation to see if there are any special instructions.

As an alternative to following these instructions, you may wish to try Arne Schirmacher's unofficial and unsupported Bugzilla Installer, which installs Bugzilla and all its prerequisites on Linux or Solaris systems.

This guide assumes that you have administrative access to the Bugzilla machine. It not possible to install and run Bugzilla itself without administrative access except in the very unlikely event that every single prerequisite is already installed.

The installation process may make your machine insecure for short periods of time. Make sure there is a firewall between you and the Internet.

You are strongly recommended to make a backup of your system before installing Bugzilla (and at regular intervals thereafter :-).

In outline, the installation proceeds as follows:

1. Install Perl (&min-perl-ver; or above)

2. Install a Database Engine

3. Install a Webserver

4. Install Bugzilla

5. Install Perl modules

6. Install a Mail Transfer Agent (Sendmail 8.7 or above, or an MTA that is Sendmail-compatible with at least this version)

7. Configure all of the above.

### Perl

Installed Version Test: `perl -v`

Any machine that doesn't have Perl on it is a sad machine indeed. If you don't have it and your OS doesn't provide official packages, visit . Although Bugzilla runs with Perl &min-perl-ver;, it's a good idea to be using the latest stable version.

### Database Engine

From Bugzilla 2.20, support is included for using both the MySQL and PostgreSQL database servers. You only require one of these systems to make use of Bugzilla.

#### MySQL

Installed Version Test: `mysql -V`

If you don't have it and your OS doesn't provide official packages, visit . You need MySQL version &min-mysql-ver; or higher.

Many of the binary versions of MySQL store their data files in `/var`. On some Unix systems, this is part of a smaller root partition, and may not have room for your bug database. To change the data directory, you have to build MySQL from source yourself, and set it as an option to `configure`.

If you install from something other than a packaging/installation system, such as .rpm (Redhat Package), .deb (Debian Package), .exe (Windows Executable), or .msi (Microsoft Installer), make sure the MySQL server is started when the machine boots.

#### PostgreSQL

Installed Version Test: `psql -V`

If you don't have it and your OS doesn't provide official packages, visit . You need PostgreSQL version &min-pg-ver; or higher.

If you install from something other than a packaging/installation system, such as .rpm (Redhat Package), .deb (Debian Package), .exe (Windows Executable), or .msi (Microsoft Installer), make sure the PostgreSQL server is started when the machine boots.

### Web Server

Installed Version Test: view the default welcome page at http://<your-machine>/

You have freedom of choice here, pretty much any web server that is capable of running CGI scripts will work. However, we strongly recommend using the Apache web server (either 1.3.x or 2.x), and the installation instructions usually assume you are using it. If you have got Bugzilla working using another web server, please share your experiences with us by filing a bug in &bzg-bugs;.

If you don't have Apache and your OS doesn't provide official packages, visit .

### Bugzilla

Download a Bugzilla tarball (or check it out from CVS) and place it in a suitable directory, accessible by the default web server user (probably apache or www). Good locations are either directly in the web server's document directories or in `/usr/local` with a symbolic link to the web server's document directories or an alias in the web server's configuration.

The default Bugzilla distribution is NOT designed to be placed in a `cgi-bin` directory. This includes any directory which is configured using the `ScriptAlias` directive of Apache.

Once all the files are in a web accessible directory, make that directory writable by your web server's user. This is a temporary step until you run the `checksetup.pl` script, which locks down your installation.

### Perl Modules

Bugzilla's installation process is based on a script called `checksetup.pl`. The first thing it checks is whether you have appropriate versions of all the required Perl modules. The aim of this section is to pass this check. When it passes, proceed to .

At this point, you need to `su` to root. You should remain as root until the end of the install. To check you have the required modules, run:

    bash# ./checksetup.pl --check-modules

`checksetup.pl` will print out a list of the required and optional Perl modules, together with the versions (if any) installed on your machine. The list of required modules is reasonably long; however, you may already have several of them installed.

There is a meta-module called Bundle::Bugzilla, which installs all the other modules with a single command. You should use this if you are running Perl 5.6.1 or above.

The preferred way of installing Perl modules is via CPAN on Unix, or PPM on Windows (see ). These instructions assume you are using CPAN; if for some reason you need to install the Perl modules manually, see .

    bash# perl -MCPAN -e 'install "<modulename>"'

If you using Bundle::Bugzilla, invoke the magic CPAN command on it. Otherwise, you need to work down the list of modules that `checksetup.pl` says are required, in the order given, invoking the command on each.

Many people complain that Perl modules will not install for them. Most times, the error messages complain that they are missing a file in @INC. Virtually every time, this error is due to permissions being set too restrictively for you to compile Perl modules or not having the necessary Perl development libraries installed on your system. Consult your local UNIX systems administrator for help solving these permissions issues; if you are the local UNIX sysadmin, please consult the newsgroup/mailing list for further assistance or hire someone to help you out.

If you are using a package-based system, and attempting to install the Perl modules from CPAN, you may need to install the "development" packages for MySQL and GD before attempting to install the related Perl modules. The names of these packages will vary depending on the specific distribution you are using, but are often called `<packagename>-devel`.

Here is a complete list of modules and their minimum versions. Some modules have special installation notes, which follow.

Required Perl modules:

1. CGI &min-cgi-ver; or CGI &min-mp-cgi-ver; if using mod_perl

2. Date::Format (&min-date-format-ver;)

3. DBI (&min-dbi-ver;)

4. DBD::mysql (&min-dbd-mysql-ver;) if using MySQL

5. DBD::Pg (&min-dbd-pg-ver;) if using PostgreSQL

6. File::Spec (&min-file-spec-ver;)

7. Template (&min-template-ver;)

8. Email::Send (&min-email-send-ver;)

9. Email::MIME::Modifier (&min-email-mime-modifier-ver;)

Optional Perl modules:

1. GD (&min-gd-ver;) for bug charting

2. Template::Plugin::GD::Image (&min-gd-ver;) for Graphical Reports

3. Chart::Base (&min-chart-base-ver;) for bug charting

4. GD::Graph (&min-gd-graph-ver;) for bug charting

5. GD::Text (&min-gd-text-ver;) for bug charting

6. XML::Twig (&min-xml-twig-ver;) for bug import/export

7. MIME::Parser (&min-mime-parser-ver;) for bug import/export

8. LWP::UserAgent (&min-lwp-useragent-ver;) for Automatic Update Notifications

9. PatchReader (&min-patchreader-ver;) for pretty HTML view of patches

10. Image::Magick (&min-image-magick-ver;) for converting BMP image attachments to PNG

11. Net::LDAP (&min-net-ldap-ver;) for LDAP Authentication

12. Authen::Radius (&min-authen-radius-ver;) for RADIUS Authentication

13. SOAP::Lite (&min-soap-lite-ver;) for the web service interface

14. HTML::Parser (&min-html-parser-ver;) for More HTML in Product/Group Descriptions

15. HTML::Scrubber (&min-html-scrubber-ver;) for More HTML in Product/Group Descriptions

16. Email::MIME::Attachment::Stripper (&min-email-mime-attachment-stripper-ver;) for Inbound Email

17. Email::Reply (&min-email-reply-ver;) for Inbound Email

18. mod_perl2 (&min-mod_perl2-ver;) for mod_perl

19. CGI (&min-cgi-ver;) for mod_perl

#### DBD::mysql

The installation process will ask you a few questions about the desired compilation target and your MySQL installation. For most of the questions the provided default will be adequate, but when asked if your desired target is the MySQL or mSQL packages, you should select the MySQL-related ones. Later you will be asked if you wish to provide backwards compatibility with the older MySQL packages; you should answer YES to this question. The default is NO.

A host of 'localhost' should be fine. A testing user of 'test', with a null password, should have sufficient access to run tests on the 'test' database which MySQL creates upon installation.

#### Template Toolkit (&min-template-ver;)

When you install Template Toolkit, you'll get asked various questions about features to enable. The defaults are fine, except that it is recommended you use the high speed XS Stash of the Template Toolkit, in order to achieve best performance.

#### GD (&min-gd-ver;)

The GD module is only required if you want graphical reports.

The Perl GD module requires some other libraries that may or may not be installed on your system, including `libpng` and `libgd`. The full requirements are listed in the Perl GD module README. If compiling GD fails, it's probably because you're missing a required library.

The version of the GD module you need is very closely tied to the `libgd` version installed on your system. If you have a version 1.x of `libgd` the 2.x versions of the GD module won't work for you.

#### Chart::Base (&min-chart-base-ver;)

The Chart::Base module is only required if you want graphical reports. Note that earlier versions that 0.99c used GIFs, which are no longer supported by the latest versions of GD.

#### GD::Graph (&min-gd-graph-ver;)

The GD::Graph module is only required if you want graphical reports.

#### GD::Text (&min-gd-text-ver;)

The GD::Text module is only required if you want graphical reports.

#### XML::Twig (&min-xml-twig-ver;)

The XML::Twig module is only required if you want to import XML bugs using the `importxml.pl` script. This is required to use Bugzilla's "move bugs" feature; you may also want to use it for migrating from another bug database.

#### SOAP::Lite (&min-soap-lite-ver;)

Installing SOAP::Lite enables your Bugzilla installation to be accessible at a standardized Web Service interface (SOAP/XML-RPC) by third-party applications via HTTP(S).

#### PatchReader (&min-patchreader-ver;)

The PatchReader module is only required if you want to use Patch Viewer, a Bugzilla feature to show code patches in your web browser in a more readable form.

### Mail Transfer Agent (MTA)

Bugzilla is dependent on the availability of an e-mail system for its user authentication and for other tasks.

This is not entirely true. It is possible to completely disable email sending, or to have Bugzilla store email messages in a file instead of sending them. However, this is mainly intended for testing, as disabling or diverting email on a production machine would mean that users could miss important events (such as bug changes or the creation of new accounts).

For more information, see the mail_delivery_method parameter in .

On Linux, any Sendmail-compatible MTA (Mail Transfer Agent) will suffice. Sendmail, Postfix, qmail and Exim are examples of common MTAs. Sendmail is the original Unix MTA, but the others are easier to configure, and therefore many people replace Sendmail with Postfix or Exim. They are drop-in replacements, so Bugzilla will not distinguish between them.

If you are using Sendmail, version 8.7 or higher is required. If you are using a Sendmail-compatible MTA, it must be congruent with at least version 8.7 of Sendmail.

Consult the manual for the specific MTA you choose for detailed installation instructions. Each of these programs will have their own configuration files where you must configure certain parameters to ensure that the mail is delivered properly. They are implemented as services, and you should ensure that the MTA is in the auto-start list of services for the machine.

If a simple mail sent with the command-line 'mail' program succeeds, then Bugzilla should also be fine.

### Installing Bugzilla on mod_perl

It is now possible to run the Bugzilla software under `mod_perl` on Apache. `mod_perl` has some additional requirements to that of running Bugzilla under `mod_cgi` (the standard and previous way).

Bugzilla requires `mod_perl` to be installed, which can be obtained from - Bugzilla requires version &min-mod_perl2-ver; (AKA 2.0.0-RC5) to be installed.

Bugzilla also requires a more up-to-date version of the CGI perl module to be installed, version &min-mp-cgi-ver; as opposed to &min-cgi-ver;

## Configuration

Poorly-configured MySQL and Bugzilla installations have given attackers full access to systems in the past. Please take the security parts of these guidelines seriously, even for Bugzilla machines hidden away behind your firewall. Be certain to read for some important security tips.

### localconfig

You should now run `checksetup.pl` again, this time without the `--check-modules` switch.

    bash# ./checksetup.pl

This time, `checksetup.pl` should tell you that all the correct modules are installed and will display a message about, and write out a file called, `localconfig`. This file contains the default settings for a number of Bugzilla parameters.

Load this file in your editor. The only value you need to change is $db_pass, the password for the user you will create for your database. Pick a strong password (for simplicity, it should not contain single quote characters) and put it here.

You may need to change the value of webservergroup if your web server does not run in the "apache" group. On Debian, for example, Apache runs in the "www-data" group. If you are going to run Bugzilla on a machine where you do not have root access (such as on a shared web hosting account), you will need to leave webservergroup empty, ignoring the warnings that `checksetup.pl` will subsequently display every time it is run.

If you are using suexec, you should use your own primary group for webservergroup rather than leaving it empty, and see the additional directions in the suexec section .

The other options in the `localconfig` file are documented by their accompanying comments. If you have a slightly non-standard MySQL setup, you may wish to change one or more of the other "$db_*" parameters.

You may also wish to change the names of the priorities, severities, operating systems and platforms for your installation. However, you can always change these after installation has finished; if you then re-run `checksetup.pl`, the changes will get picked up.

### Database Server

This section deals with configuring your database server for use with Bugzilla. Currently, MySQL () and PostgreSQL () are available.

#### Bugzilla Database Schema

The Bugzilla database schema is available at Ravenbrook. This very valuable tool can generate a written description of the Bugzilla database schema for any version of Bugzilla. It can also generate a diff between two versions to help someone see what has changed.

#### MySQL

MySQL's default configuration is very insecure. has some good information for improving your installation's security.

##### Allow large attachments

By default, MySQL will only accept packets up to 64Kb in size. If you want to have attachments larger than this, you will need to modify your `/etc/my.cnf` as below.

      [mysqld]
      # Allow packets up to 1M
      max_allowed_packet=1M

There is also a parameter in Bugzilla called 'maxattachmentsize' (default = 1000 Kb) that controls the maximum allowable attachment size. Attachments larger than either the 'max_allowed_packet' or 'maxattachmentsize' value will not be accepted by Bugzilla.

This does not affect Big Files, attachments that are stored directly on disk instead of in the database. Their maximum size is controlled using the 'maxlocalattachment' parameter.

##### Allow small words in full-text indexes

By default, words must be at least four characters in length in order to be indexed by MySQL's full-text indexes. This causes a lot of Bugzilla specific words to be missed, including "cc", "ftp" and "uri".

MySQL can be configured to index those words by setting the ft_min_word_len param to the minimum size of the words to index. This can be done by modifying the `/etc/my.cnf` according to the example below:

      [mysqld]
      # Allow small words in full-text indexes
      ft_min_word_len=2

Rebuilding the indexes can be done based on documentation found at .

##### Add a user to MySQL

You need to add a new MySQL user for Bugzilla to use. (It's not safe to have Bugzilla use the MySQL root account.) The following instructions assume the defaults in `localconfig`; if you changed those, you need to modify the SQL command appropriately. You will need the $db_pass password you set in `localconfig` in .

We use an SQL `GRANT` command to create a bugs user. This also restricts the bugsuser to operations within a database called bugs, and only allows the account to connect from localhost. Modify it to reflect your setup if you will be connecting from another machine or as a different user.

Run the `mysql` command-line client and enter:

      mysql> GRANT SELECT, INSERT,
               UPDATE, DELETE, INDEX, ALTER, CREATE, LOCK TABLES,
               CREATE TEMPORARY TABLES, DROP, REFERENCES ON bugs.*
               TO bugs@localhost IDENTIFIED BY '$db_pass';
               mysql> FLUSH PRIVILEGES;

##### Permit attachments table to grow beyond 4GB

By default, MySQL will limit the size of a table to 4GB. This limit is present even if the underlying filesystem has no such limit. To set a higher limit, follow these instructions.

After you have completed the rest of the installation (or at least the database setup parts), you should run the `MySQL` command-line client and enter the following, replacing `$bugs_db` with your Bugzilla database name (bugs by default):

                mysql> use $bugs_db
                mysql> ALTER TABLE attachments
                AVG_ROW_LENGTH=1000000, MAX_ROWS=20000;

The above command will change the limit to 20GB. Mysql will have to make a temporary copy of your entire table to do this. Ideally, you should do this when your attachments table is still small.

This does not affect Big Files, attachments that are stored directly on disk instead of in the database.

#### PostgreSQL

##### Add a User to PostgreSQL

You need to add a new user to PostgreSQL for the Bugzilla application to use when accessing the database. The following instructions assume the defaults in `localconfig`; if you changed those, you need to modify the commands appropriately. You will need the $db_pass password you set in `localconfig` in .

On most systems, to create the user in PostgreSQL, you will need to login as the root user, and then

     bash# su - postgres

As the postgres user, you then need to create a new user:

     bash$ createuser -U postgres -dAP bugs

When asked for a password, provide the password which will be set as $db_pass in `localconfig`. The created user will have the ability to create databases and will not be able to create new users.

##### Configure PostgreSQL

Now, you will need to edit `pg_hba.conf` which is usually located in `/var/lib/pgsql/data/`. In this file, you will need to add a new line to it as follows:

`host all bugs 127.0.0.1 255.255.255.255 md5`

This means that for TCP/IP (host) connections, allow connections from '127.0.0.1' to 'all' databases on this server from the 'bugs' user, and use password authentication (md5) for that user.

Now, you will need to restart PostgreSQL, but you will need to fully stop and start the server rather than just restarting due to the possibility of a change to `postgresql.conf`. After the server has restarted, you will need to edit `localconfig`, finding the `$db_driver` variable and setting it to `Pg` and changing the password in `$db_pass` to the one you picked previously, while setting up the account.

### checksetup.pl

Next, rerun `checksetup.pl`. It reconfirms that all the modules are present, and notices the altered localconfig file, which it assumes you have edited to your satisfaction. It compiles the UI templates, connects to the database using the 'bugs' user you created and the password you defined, and creates the 'bugs' database and the tables therein.

After that, it asks for details of an administrator account. Bugzilla can have multiple administrators - you can create more later - but it needs one to start off with. Enter the email address of an administrator, his or her full name, and a suitable Bugzilla password.

`checksetup.pl` will then finish. You may rerun `checksetup.pl` at any time if you wish.

### Web server

Configure your web server according to the instructions in the appropriate section. (If it makes a difference in your choice, the Bugzilla Team recommends Apache.) To check whether your web server is correctly configured, try to access `testagent.cgi` from your web server. If "OK" is displayed, then your configuration is successful. Regardless of which web server you are using, however, ensure that sensitive information is not remotely available by properly applying the access controls in . You can run `testserver.pl` to check if your web server serves Bugzilla files as expected.

#### Bugzilla using Apache

You have two options for running Bugzilla under Apache - mod_cgi (the default) and mod_perl (new in Bugzilla 2.23)

##### Apache httpd with mod_cgi

To configure your Apache web server to work with Bugzilla while using mod_cgi, do the following:

1. Load `httpd.conf` in your editor. In Fedora and Red Hat Linux, this file is found in `/etc/httpd/conf`.

2. Apache uses `<Directory>` directives to permit fine-grained permission setting. Add the following lines to a directive that applies to the location of your Bugzilla installation. (If such a section does not exist, you'll want to add one.) In this example, Bugzilla has been installed at `/var/www/html/bugzilla`.

           <Directory /var/www/html/bugzilla>
           AddHandler cgi-script .cgi
           Options +Indexes +ExecCGI
           DirectoryIndex index.cgi
           AllowOverride Limit
           </Directory>

   These instructions: allow apache to run .cgi files found within the bugzilla directory; instructs the server to look for a file called `index.cgi` if someone only types the directory name into the browser; and allows Bugzilla's `.htaccess` files to override global permissions.

   It is possible to make these changes globally, or to the directive controlling Bugzilla's parent directory (e.g. `<Directory /var/www/html/>`). Such changes would also apply to the Bugzilla directory... but they would also apply to many other places where they may or may not be appropriate. In most cases, including this one, it is better to be as restrictive as possible when granting extra access.

3. `checksetup.pl` can set tighter permissions on Bugzilla's files and directories if it knows what group the web server runs as. Find the `Group` line in `httpd.conf`, place the value found there in the $webservergroup variable in `localconfig`, then rerun `checksetup.pl`.

4. Optional: If Bugzilla does not actually reside in the webspace directory, but instead has been symbolically linked there, you will need to add the following to the `Options` line of the Bugzilla `<Directory>` directive (the same one as in the step above):

           +FollowSymLinks

   Without this directive, Apache will not follow symbolic links to places outside its own directory structure, and you will be unable to run Bugzilla.

##### Apache httpd with mod_perl

Some configuration is required to make Bugzilla work with Apache and mod_perl

1. Load `httpd.conf` in your editor. In Fedora and Red Hat Linux, this file is found in `/etc/httpd/conf`.

2. Add the following information to your httpd.conf file, substituting where appropriate with your own local paths.

   This should be used instead of the <Directory> block shown above. This should also be above any other `mod_perl` directives within the `httpd.conf` and must be specified in the order as below.

   You should also ensure that you have disabled `KeepAlive` support in your Apache install when utilizing Bugzilla under mod_perl

           PerlSwitches -I/var/www/html/bugzilla -I/var/www/html/bugzilla/lib -w -T
           PerlConfigRequire /var/www/html/bugzilla/mod_perl.pl

3. `checksetup.pl` can set tighter permissions on Bugzilla's files and directories if it knows what group the web server runs as. Find the `Group` line in `httpd.conf`, place the value found there in the $webservergroup variable in `localconfig`, then rerun `checksetup.pl`.

On restarting Apache, Bugzilla should now be running within the mod_perl environment. Please ensure you have run checksetup.pl to set permissions before you restart Apache.

Please bear the following points in mind when looking at using Bugzilla under mod_perl:

- mod_perl support in Bugzilla can take up a HUGE amount of RAM. You could be looking at 30MB per httpd child, easily. Basically, you just need a lot of RAM. The more RAM you can get, the better. mod_perl is basically trading RAM for speed. At least 2GB total system RAM is recommended for running Bugzilla under mod_perl.

- Under mod_perl, you have to restart Apache if you make any manual change to any Bugzilla file. You can't just reload--you have to actually restart the server (as in make sure it stops and starts again). You can change localconfig and the params file manually, if you want, because those are re-read every time you load a page.

- You must run in Apache's Prefork MPM (this is the default). The Worker MPM may not work--we haven't tested Bugzilla's mod_perl support under threads. (And, in fact, we're fairly sure it won't work.)

- Bugzilla generally expects to be the only mod_perl application running on your entire server. It may or may not work if there are other applications also running under mod_perl. It does try its best to play nice with other mod_perl applications, but it still may have conflicts.

- It is recommended that you have one Bugzilla instance running under mod_perl on your server. Bugzilla has not been tested with more than one instance running.

#### Microsoft Internet Information Services

If you are running Bugzilla on Windows and choose to use Microsoft's Internet Information Services or Personal Web Server you will need to perform a number of other configuration steps as explained below. You may also want to refer to the following Microsoft Knowledge Base articles: 245225 HOW TO: Configure and Test a PERL Script with IIS 4.0, 5.0, and 5.1 (for Internet Information Services) and 231998 HOW TO: FP2000: How to Use Perl with Microsoft Personal Web Server on Windows 95/98 (for Personal Web Server).

You will need to create a virtual directory for the Bugzilla install. Put the Bugzilla files in a directory that is named something other than what you want your end-users accessing. That is, if you want your users to access your Bugzilla installation through http://<yourdomainname>/Bugzilla, then do not put your Bugzilla files in a directory named Bugzilla. Instead, place them in a different location, and then use the IIS Administration tool to create a Virtual Directory named "Bugzilla" that acts as an alias for the actual location of the files. When creating that virtual directory, make sure you add the Execute (such as ISAPI applications or CGI) access permission.

You will also need to tell IIS how to handle Bugzilla's .cgi files. Using the IIS Administration tool again, open up the properties for the new virtual directory and select the Configuration option to access the Script Mappings. Create an entry mapping .cgi to:

    <full path to perl.exe >\perl.exe -x<full path to Bugzilla> -wT "%s" %s

For example:

    c:\perl\bin\perl.exe -xc:\bugzilla -wT "%s" %s

The ActiveState install may have already created an entry for .pl files that is limited to GET,HEAD,POST. If so, this mapping should be removed as Bugzilla's .pl files are not designed to be run via a web server.

IIS will also need to know that the index.cgi should be treated as a default document. On the Documents tab page of the virtual directory properties, you need to add index.cgi as a default document type. If you wish, you may remove the other default document types for this particular virtual directory, since Bugzilla doesn't use any of them.

Also, and this can't be stressed enough, make sure that files such as `localconfig` and your `data` directory are secured as described in .

### Bugzilla

Your Bugzilla should now be working. Access `http://<your-bugzilla-server>/` - you should see the Bugzilla front page. If not, consult the Troubleshooting section, .

The URL above may be incorrect if you installed Bugzilla into a subdirectory or used a symbolic link from your web site root to the Bugzilla directory.

Log in with the administrator account you defined in the last `checksetup.pl` run. You should go through the parameters on the Edit Parameters page (see link in the footer) and see if there are any you wish to change. They key parameters are documented in ; you should certainly alter `maintainer` and `urlbase`; you may also want to alter `cookiepath` or `requirelogin`.

This would also be a good time to revisit the `localconfig` file and make sure that the names of the priorities, severities, platforms and operating systems are those you wish to use when you start creating bugs. Remember to rerun `checksetup.pl` if you change it.

Bugzilla has several optional features which require extra configuration. You can read about those in .

## Optional Additional Configuration

Bugzilla has a number of optional features. This section describes how to configure or enable them.

### Bug Graphs

If you have installed the necessary Perl modules you can start collecting statistics for the nifty Bugzilla graphs.

    bash# crontab -e

This should bring up the crontab file in your editor. Add a cron entry like this to run `collectstats.pl` daily at 5 after midnight:

    5 0 * * * cd <your-bugzilla-directory> ; ./collectstats.pl

After two days have passed you'll be able to view bug graphs from the Reports page.

When upgrading Bugzilla, this format may change. To create new status data, (re)move old data and run the following commands:

            bash$
            cd <your-bugzilla-directory>
            bash$
            ./collectstats.pl --regenerate

Windows does not have 'cron', but it does have the Task Scheduler, which performs the same duties. There are also third-party tools that can be used to implement cron, such as nncron.

### Dependency Charts

As well as the text-based dependency trees, Bugzilla also supports a graphical view of dependency relationships, using a package called 'dot'. Exactly how this works is controlled by the 'webdotbase' parameter, which can have one of three values:

1. A complete file path to the command 'dot' (part of GraphViz) will generate the graphs locally

2. A URL prefix pointing to an installation of the webdot package will generate the graphs remotely

3. A blank value will disable dependency graphing.

The easiest way to get this working is to install GraphViz. If you do that, you need to enable server-side image maps in Apache. Alternatively, you could set up a webdot server, or use the AT&T public webdot server. This is the default for the webdotbase param, but it's often overloaded and slow. Note that AT&T's server won't work if Bugzilla is only accessible using HARTS. Editor's note: What the heck is HARTS? Google doesn't know...

### The Whining Cron

What good are bugs if they're not annoying? To help make them more so you can set up Bugzilla's automatic whining system to complain at engineers which leave their bugs in the NEW or REOPENED state without triaging them.

This can be done by adding the following command as a daily crontab entry, in the same manner as explained above for bug graphs. This example runs it at 12.55am.

    55 0 * * * cd <your-bugzilla-directory> ; ./whineatnews.pl

Windows does not have 'cron', but it does have the Task Scheduler, which performs the same duties. There are also third-party tools that can be used to implement cron, such as nncron.

### Whining

As of Bugzilla 2.20, users can configure Bugzilla to regularly annoy them at regular intervals, by having Bugzilla execute saved searches at certain times and emailing the results to the user. This is known as "Whining". The process of configuring Whining is described in , but for it to work a Perl script must be executed at regular intervals.

This can be done by adding the following command as a daily crontab entry, in the same manner as explained above for bug graphs. This example runs it every 15 minutes.

    */15 * * * * cd <your-bugzilla-directory> ; ./whine.pl

Whines can be executed as often as every 15 minutes, so if you specify longer intervals between executions of whine.pl, some users may not be whined at as often as they would expect. Depending on the person, this can either be a very Good Thing or a very Bad Thing.

Windows does not have 'cron', but it does have the Task Scheduler, which performs the same duties. There are also third-party tools that can be used to implement cron, such as nncron.

### Patch Viewer

Patch Viewer is the engine behind Bugzilla's graphical display of code patches. You can integrate this with copies of the `cvs`, `lxr` and `bonsai` tools if you have them, by giving the locations of your installation of these tools in `editparams.cgi`.

Patch Viewer also optionally will use the `cvs`, `diff` and `interdiff` command-line utilities if they exist on the system. Interdiff can be obtained from . If these programs are not in the system path, you can configure their locations in `localconfig`.

### RADIUS Authentication

RADIUS authentication is a module for Bugzilla's plugin authentication architecture. Most caveats that apply to LDAP authentication apply to RADIUS authentication as well.

Parameters required to use RADIUS Authentication:

user_verify_class

  If you want to list RADIUS here, make sure to have set up the other parameters listed below. Unless you have other (working) authentication methods listed as well, you may otherwise not be able to log back in to Bugzilla once you log out. If this happens to you, you will need to manually edit `data/params` and set user_verify_class to DB.

RADIUS_server

  This parameter should be set to the name (and optionally the port) of your RADIUS server.

RADIUS_secret

  This parameter should be set to the RADIUS server's secret.

RADIUS_email_suffix

  Bugzilla needs an e-mail address for each user account. Therefore, it needs to determine the e-mail address corresponding to a RADIUS user. Bugzilla offers only a simple way to do this: it can concatenate a suffix to the RADIUS user name to convert it into an e-mail address. You can specify this suffix in the RADIUS_email_suffix parameter.

  If this simple solution does not work for you, you'll probably need to modify `Bugzilla/Auth/Verify/RADIUS.pm` to match your requirements.

### LDAP Authentication

LDAP authentication is a module for Bugzilla's plugin authentication architecture.

The existing authentication scheme for Bugzilla uses email addresses as the primary user ID, and a password to authenticate that user. All places within Bugzilla where you need to deal with user ID (e.g assigning a bug) use the email address. The LDAP authentication builds on top of this scheme, rather than replacing it. The initial log in is done with a username and password for the LDAP directory. Bugzilla tries to bind to LDAP using those credentials, and if successful, try to map this account to a Bugzilla account. If a LDAP mail attribute is defined, the value of this attribute is used, otherwise emailsuffix parameter is appended to LDAP username to form a full email address. If an account for this address already exists in your Bugzilla system, it will log in to that account. If no account for that email address exists, one is created at the time of login. (In this case, Bugzilla will attempt to use the "displayName" or "cn" attribute to determine the user's full name.) After authentication, all other user-related tasks are still handled by email address, not LDAP username. You still assign bugs by email address, query on users by email address, etc.

Because the Bugzilla account is not created until the first time a user logs in, a user who has not yet logged is unknown to Bugzilla. This means they cannot be used as an assignee or QA contact (default or otherwise), added to any cc list, or any other such operation. One possible workaround is the `bugzilla_ldapsync.rb` script in the `contrib` directory. Another possible solution is fixing bug 201069.

Parameters required to use LDAP Authentication:

user_verify_class

  If you want to list LDAP here, make sure to have set up the other parameters listed below. Unless you have other (working) authentication methods listed as well, you may otherwise not be able to log back in to Bugzilla once you log out. If this happens to you, you will need to manually edit `data/params` and set user_verify_class to DB.

LDAPserver

  This parameter should be set to the name (and optionally the port) of your LDAP server. If no port is specified, it assumes the default LDAP port of 389.

  Ex. ldap.company.com or ldap.company.com:3268

  You can also specify a LDAP URI, so as to use other protocols, such as LDAPS or LDAPI. If port was not specified in the URI, the default is either 389 or 636 for 'LDAP' and 'LDAPS' schemes respectively.

  Ex. ldap://ldap.company.com, ldaps://ldap.company.com or ldapi://%2fvar%2flib%2fldap_sock

LDAPbinddn [Optional]

  Some LDAP servers will not allow an anonymous bind to search the directory. If this is the case with your configuration you should set the LDAPbinddn parameter to the user account Bugzilla should use instead of the anonymous bind.

  Ex. cn=default,cn=user:password

LDAPBaseDN

  The LDAPBaseDN parameter should be set to the location in your LDAP tree that you would like to search for email addresses. Your uids should be unique under the DN specified here.

  Ex. ou=People,o=Company

LDAPuidattribute

  The LDAPuidattribute parameter should be set to the attribute which contains the unique UID of your users. The value retrieved from this attribute will be used when attempting to bind as the user to confirm their password.

  Ex. uid

LDAPmailattribute

  The LDAPmailattribute parameter should be the name of the attribute which contains the email address your users will enter into the Bugzilla login boxes.

  Ex. mail

### Serving Alternate Formats with the right MIME type

Some Bugzilla pages have alternate formats, other than just plain HTML. In particular, a few Bugzilla pages can output their contents as either XUL (a special Mozilla format, that looks like a program GUI) or RDF (a type of structured XML that can be read by various programs).

In order for your users to see these pages correctly, Apache must send them with the right MIME type. To do this, add the following lines to your Apache configuration, either in the `<VirtualHost>` section for your Bugzilla, or in the `<Directory>` section for your Bugzilla:

    AddType application/vnd.mozilla.xul+xml .xul
    AddType application/rdf+xml .rdf

## Multiple Bugzilla databases with a single installation

The previous instructions referred to a standard installation, with one unique Bugzilla database. However, you may want to host several distinct installations, without having several copies of the code. This is possible by using the PROJECT environment variable. When accessed, Bugzilla checks for the existence of this variable, and if present, uses its value to check for an alternative configuration file named `localconfig.<PROJECT>` in the same location as the default one (`localconfig`). It also checks for customized templates in a directory named `<PROJECT>` in the same location as the default one (`template/<langcode>`). By default this is `template/en/default` so PROJECT's templates would be located at `template/en/PROJECT`.

To set up an alternate installation, just export PROJECT=foo before running `checksetup.pl` for the first time. It will result in a file called `localconfig.foo` instead of `localconfig`. Edit this file as described above, with reference to a new database, and re-run `checksetup.pl` to populate it. That's all.

Now you have to configure the web server to pass this environment variable when accessed via an alternate URL, such as virtual host for instance. The following is an example of how you could do it in Apache, other Webservers may differ.

    <VirtualHost 212.85.153.228:80>
        ServerName foo.bar.baz
        SetEnv PROJECT foo
        Alias /bugzilla /var/www/bugzilla
    </VirtualHost>

Don't forget to also export this variable before accessing Bugzilla by other means, such as cron tasks for instance.

## OS-Specific Installation Notes

Many aspects of the Bugzilla installation can be affected by the operating system you choose to install it on. Sometimes it can be made easier and others more difficult. This section will attempt to help you understand both the difficulties of running on specific operating systems and the utilities available to make it easier.

If you have anything to add or notes for an operating system not covered, please file a bug in &bzg-bugs;.

### Microsoft Windows

Making Bugzilla work on Windows is more difficult than making it work on Unix. For that reason, we still recommend doing so on a Unix based system such as GNU/Linux. That said, if you do want to get Bugzilla running on Windows, you will need to make the following adjustments. A detailed step-by-step installation guide for Windows is also available if you need more help with your installation.

#### Win32 Perl

Perl for Windows can be obtained from ActiveState. You should be able to find a compiled binary at . The following instructions assume that you are using version 5.8.1 of ActiveState.

These instructions are for 32-bit versions of Windows. If you are using a 64-bit version of Windows, you will need to install 32-bit Perl in order to install the 32-bit modules as described below.

#### Perl Modules on Win32

Bugzilla on Windows requires the same perl modules found in . The main difference is that windows uses PPM instead of CPAN.

    C:\perl> ppm install <module name>

The best source for the Windows PPM modules needed for Bugzilla is probably the Bugzilla Test Server (aka 'Landfill'), so you should add the Landfill package repository as follows:

    ppm repo add landfill http://www.landfill.bugzilla.org/ppm/

In versions prior to 5.8.8 build 819 of PPM the command is

    ppm repository add landfill http://www.landfill.bugzilla.org/ppm/

The PPM repository stores modules in 'packages' that may have a slightly different name than the module. If retrieving these modules from there, you will need to pay attention to the information provided when you run `checksetup.pl` as it will tell you what package you'll need to install.

If you are behind a corporate firewall, you will need to let the ActiveState PPM utility know how to get through it to access the repositories by setting the HTTP_proxy system environmental variable. For more information on setting that variable, see the ActiveState documentation.

#### Code changes required to run on Win32

Bugzilla on Win32 is supported out of the box from version 2.20; this means that no code changes are required to get Bugzilla running.

#### Serving the web pages

As is the case on Unix based systems, any web server should be able to handle Bugzilla; however, the Bugzilla Team still recommends Apache whenever asked. No matter what web server you choose, be sure to pay attention to the security notes in . More information on configuring specific web servers can be found in .

If using Apache on windows, you can set the ScriptInterpreterSource directive in your Apache config to avoid having to modify the first line of every script to contain your path to Perl instead of `/usr/bin/perl`. When setting `ScriptInterpreterSource`, do not forget to specify the `-T` flag to enable the taint mode. For example: `C:\Perl\bin\perl.exe -T`.

#### Sending Email

To enable Bugzilla to send email on Windows, the server running the Bugzilla code must be able to connect to, or act as, an SMTP server.

### Mac OS X

Making Bugzilla work on Mac OS X requires the following adjustments.

#### Sendmail

In Mac OS X 10.3 and later, Postfix is used as the built-in email server. Postfix provides an executable that mimics sendmail enough to fool Bugzilla, as long as Bugzilla can find it.

As of version 2.20, Bugzilla will be able to find the fake sendmail executable without any assistance. However, you will have to turn on the sendmailnow parameter before you do anything that would result in email being sent. For more information, see the description of the sendmailnow parameter in .

#### Libraries & Perl Modules on Mac OS X

Apple did not include the GD library with Mac OS X. Bugzilla needs this for bug graphs.

You can install it using a program called Fink, which is similar in nature to the CPAN installer, but installs common GNU utilities. Fink is available from .

Follow the instructions for setting up Fink. Once it's installed, you'll want to use it to install the `gd2` package.

It will prompt you for a number of dependencies, type 'y' and hit enter to install all of the dependencies and then watch it work. You will then be able to use CPAN to install the GD Perl module.

To prevent creating conflicts with the software that Apple installs by default, Fink creates its own directory tree at `/sw` where it installs most of the software that it installs. This means your libraries and headers will be at `/sw/lib` and `/sw/include` instead of `/usr/lib` and `/usr/include`. When the Perl module config script asks where your `libgd` is, be sure to tell it `/sw/lib`.

Also available via Fink is `expat`. After using fink to install the expat package you will be able to install XML::Parser using CPAN. There is one caveat. Unlike recent versions of the GD module, XML::Parser doesn't prompt for the location of the required libraries. When using CPAN, you will need to use the following command sequence:

    # perl -MCPAN -e'look XML::Parser'
    # perl Makefile.PL EXPATLIBPATH=/sw/lib EXPATINCPATH=/sw/include
    # make; make test; make install
    # exit

The look command will download the module and spawn a new shell with the extracted files as the current working directory. The exit command will return you to your original shell.

You should watch the output from these make commands, especially make test as errors may prevent XML::Parser from functioning correctly with Bugzilla.

### Linux Distributions

Many Linux distributions include Bugzilla and its dependencies in their native package management systems. Installing Bugzilla with root access on any Linux system should be as simple as finding the Bugzilla package in the package management application and installing it using the normal command syntax. Several distributions also perform the proper web server configuration automatically on installation.

Please consult the documentation of your Linux distribution for instructions on how to install packages, or for specific instructions on installing Bugzilla with native package management tools. There is also a Bugzilla Wiki Page for distro-specific installation notes.

## UNIX (non-root) Installation Notes

### Introduction

If you are running a *NIX OS as non-root, either due to lack of access (web hosts, for example) or for security reasons, this will detail how to install Bugzilla on such a setup. It is recommended that you read through the first to get an idea on the installation steps required. (These notes will reference to steps in that guide.)

### MySQL

You may have MySQL installed as root. If you're setting up an account with a web host, a MySQL account needs to be set up for you. From there, you can create the bugs account, or use the account given to you.

You may have problems trying to set up `GRANT` permissions to the database. If you're using a web host, chances are that you have a separate database which is already locked down (or one big database with limited/no access to the other areas), but you may want to ask your system administrator what the security settings are set to, and/or run the `GRANT` command for you.

Also, you will probably not be able to change the MySQL root user password (for obvious reasons), so skip that step.

#### Running MySQL as Non-Root

##### The Custom Configuration Method

Create a file .my.cnf in your home directory (using /home/foo in this example) as follows....

    [mysqld]
    datadir=/home/foo/mymysql
    socket=/home/foo/mymysql/thesock
    port=8081

    [mysql]
    socket=/home/foo/mymysql/thesock
    port=8081

    [mysql.server]
    user=mysql
    basedir=/var/lib

    [safe_mysqld]
    err-log=/home/foo/mymysql/the.log
    pid-file=/home/foo/mymysql/the.pid

##### The Custom Built Method

You can install MySQL as a not-root, if you really need to. Build it with PREFIX set to `/home/foo/mysql`, or use pre-installed executables, specifying that you want to put all of the data files in `/home/foo/mysql/data`. If there is another MySQL server running on the system that you do not own, use the -P option to specify a TCP port that is not in use.

##### Starting the Server

After your mysqld program is built and any .my.cnf file is in place, you must initialize the databases (ONCE).

                  bash$
                  mysql_install_db

Then start the daemon with

                  bash$
                  safe_mysql &

After you start mysqld the first time, you then connect to it as "root" and `GRANT` permissions to other users. (Again, the MySQL root account has nothing to do with the *NIX root account.)

You will need to start the daemons yourself. You can either ask your system administrator to add them to system startup files, or add a crontab entry that runs a script to check on these daemons and restart them if needed.

Do NOT run daemons or other services on a server without first consulting your system administrator! Daemons use up system resources and running one may be in violation of your terms of service for any machine on which you are a user!

### Perl

On the extremely rare chance that you don't have Perl on the machine, you will have to build the sources yourself. The following commands should get your system installed with your own personal version of Perl:

            bash$
            wget http://perl.com/CPAN/src/stable.tar.gz
            bash$
            tar zvxf stable.tar.gz
            bash$
            cd perl-5.8.1 (or whatever the version of Perl is called)
            bash$
            sh Configure -de -Dprefix=/home/foo/perl
            bash$
            make && make test && make install

Once you have Perl installed into a directory (probably in `~/perl/bin`), you will need to install the Perl Modules, described below.

### Perl Modules

Installing the Perl modules as a non-root user is accomplished by running the `install-module.pl` script. For more details on this script, see `install-module.pl` documentation

### HTTP Server

Ideally, this also needs to be installed as root and run under a special web server account. As long as the web server will allow the running of *.cgi files outside of a cgi-bin, and a way of denying web access to certain files (such as a .htaccess file), you should be good in this department.

#### Running Apache as Non-Root

You can run Apache as a non-root user, but the port will need to be set to one above 1024. If you type `httpd -V`, you will get a list of the variables that your system copy of httpd uses. One of those, namely HTTPD_ROOT, tells you where that installation looks for its config information.

From there, you can copy the config files to your own home directory to start editing. When you edit those and then use the -d option to override the HTTPD_ROOT compiled into the web server, you get control of your own customized web server.

You will need to start the daemons yourself. You can either ask your system administrator to add them to system startup files, or add a crontab entry that runs a script to check on these daemons and restart them if needed.

Do NOT run daemons or other services on a server without first consulting your system administrator! Daemons use up system resources and running one may be in violation of your terms of service for any machine on which you are a user!

### Bugzilla

When you run `./checksetup.pl` to create the `localconfig` file, it will list the Perl modules it finds. If one is missing, go back and double-check the module installation from , then delete the `localconfig` file and try again.

One option in `localconfig` you might have problems with is the web server group. If you can't successfully browse to the `index.cgi` (like a Forbidden error), you may have to relax your permissions, and blank out the web server group. Of course, this may pose as a security risk. Having a properly jailed shell and/or limited access to shell accounts may lessen the security risk, but use at your own risk.

#### suexec or shared hosting

If you are running on a system that uses suexec (most shared hosting environments do this), you will need to set the webservergroup value in `localconfig` to match your primary group, rather than the one the web server runs under. You will need to run the following shell commands after running `./checksetup.pl`, every time you run it (or modify `checksetup.pl` to do them for you via the system() command).

            for i in docs graphs images js skins; do find $i -type d -exec chmod o+rx {} \; ; done
            for i in jpg gif css js png html rdf xul; do find . -name \*.$i -exec chmod o+r {} \; ; done
            find . -name .htaccess -exec chmod o+r {} \;
            chmod o+x . data data/webdot

Pay particular attention to the number of semicolons and dots. They are all important. A future version of Bugzilla will hopefully be able to do this for you out of the box.
