<section id="stepbystep">
<title>Step-by-step Install</title>
<para>Bugzilla has been successfully installed under many different
operating systems including almost all Unix clones and
<productname class="registered">Microsoft Windows</productname>. Many
operating systems have utilities that make installation easier or quirks
that make it harder. We have tried to collect that information in
<xref linkend="os-specific"/>, so be sure to check out that section before
you start your installation.
</para>
<note>
<para>Windows is one of those operating systems that has many quirks
and is not yet officially supported by the Bugzilla team. If you wish
to install Bugzilla on Windows, be sure to see
<xref linkend="os-win32"/>.
</para>
</note>
<warning>
<para>While installing Bugzilla, it is a good idea to ensure that there
is some kind of firewall between you and the rest of the Internet
as your machine may be insecure for periods during the install. Many
installation steps require an active Internet connection to complete,
but you must take care to ensure that at no point is your machine
vulnerable to an attack.</para>
</warning>
<para>This guide assumes that you already have your operating system
installed, network configured, and have administrative access to the
shell on the machine you are installing Bugzilla onto. It is possible to
install and run Bugzilla without administrative access, but you have to
either make sure all the required software is installed or get somebody
with administrative access to install it for you.

<note>
<para> Many of the binary
versions of MySQL store their data files in
<filename class="directory">/var</filename>.
On some Unix systems, this is part of a smaller root partition,
and may not have room for your bug database. You can set the data
directory as an option to <filename>configure</filename>
if you build MySQL from source yourself.</para>
</note>
<para>If you install from something other than a packaging/installation
system (such as .rpm, .dep, .exe, or .msi) you will need to configure
your system so the MySQL server daemon will come back up whenever
your machine reboots.
</para>
<para>If you wish to have attachments larger than 64K, you will have to
configure MySQL to accept large packets. This is done by adding the text
in <xref linkend="install-mysql-packets"/> to your
<filename>my.conf</filename> file. There is also a parameter in Bugzilla
for setting the maximum allowable attachment size.
<!-- TODO: xref to a param() page for max attachment size -->
You should set this value to be slightly larger than that parameter.

There are also binary versions available for many platforms, most of which
are linked to from perl.com.
Although Bugzilla runs with perl &min-perl-ver;,
it's a good idea to be up to the very latest version
if you can when running Bugzilla. As of this writing, that is Perl
version &newest-perl-ver;.</para>

<para>Many people complain that Perl modules will not install for

Virtually every time, this error is due to permissions being set too

necessary Perl development libraries installed on your system.

<para>Next, run the magic checksetup.pl script. (Many thanks to
<ulink url="mailto:holgerschurig@nikocity.de">Holger Schurig</ulink>
for writing this script!)
This script is designed to make sure your perl modules are the correct
version and your MySQL database and other
configuration options are consistent with the Bugzilla CGI files.
It will make sure Bugzilla files and directories have reasonable
permissions, set up the
<filename>data</filename>
directory, and create all the MySQL tables.
</para>

<para>This file contains a variety of settings you may need to tweak
including how Bugzilla should connect to the MySQL database.</para>
<para>The connection settings include:
<orderedlist>

<para>server's host: just use

if the MySQL server is local</para>

<listitem>
<para>Password for the
<quote>bugs_user</quote>
MySQL account; (<quote>bugs_password</quote> above)</para>
</listitem>
</orderedlist>
</para>
<para>Once you are happy with the settings,
<filename>su</filename> to the user
your web server runs as, and re-run
<filename>checksetup.pl</filename>. (Note: on some security-conscious
systems, you may need to change the login shell for the webserver
account before you can do this.)
On this second run, it will create the database and an administrator
account for which you will be prompted to provide information.</para>

<title>Dependency Charts</title>
<para>As well as the text-based dependency graphs, Bugzilla also
supports dependency graphing, using a package called 'dot'.
Exactly how this works is controlled by the 'webdotbase' parameter,
which can have one of three values:
</para>
<para>
<orderedlist>
<listitem>
<para>
A complete file path to the command 'dot' (part of

</listitem>
<listitem>
<para>
A URL prefix pointing to an installation of the webdot package will
generate the graphs remotely
</para>
</listitem>
<listitem>
<para>
A blank value will disable dependency graphing.
</para>
</listitem>
</orderedlist>
</para>
<para>So, to get this working, install

do that, you need to
<ulink url="http://httpd.apache.org/docs/mod/mod_imap.html">enable
server-side image maps</ulink> in Apache.
Alternatively, you could set up a webdot server, or use the AT&T
public webdot server (the
default for the webdotbase param). Note that AT&T's server won't work
if Bugzilla is only accessible using HARTS.

</para>
<para>
This can be done by
adding the following command as a daily crontab entry (for help on that

<title>LDAP Authentication</title>
<note>
<para>LDAP authentication has been rewritten for the 2.18 release of
Bugzilla. It no longer requires the Mozilla::LDAP module and now uses
Net::LDAP instead. This rewrite was part of a larger landing that
allowed for additional authentication schemes to be easily added
(<ulink url="http://bugzilla.mozilla.org/show_bug.cgi?id=180642">bug
180642</ulink>).
</para>
<![%bz-devel;[
<para>This patch originally landed in 21-Mar-2003 and was included
in the 2.17.4 development release.
</para>
]]>
</note>
<para>
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. This then fetches the email address
from LDAP and authenticates seamlessly in the standard Bugzilla
authentication scheme using this 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.
</para>
<caution>
<para>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 <filename>bugzilla_ldapsync.rb</filename>
script in the
<glossterm linkend="gloss-contrib"><filename class="directory">contrib</filename></glossterm> directory. Another possible solution is fixing

The GD library, which Bugzilla needs to do bug graphs, is one of
these.</para>
<para>The easiest way to get a lot of these is with a program called
Fink, which is similar in nature to the CPAN installer, but installs
common GNU utilities. Fink is available from

<para>To prevent creating conflicts with the software that Apple
installs by default, Fink creates its own directory tree at

<para>Ben FrantzDale reported success using AOL Server with Bugzilla. He
reported his experience and what appears below is based on that.

the documentation that came with your server for more information on
how to do this.

<para>Because AOL Server doesn't support <filename>.htaccess</filename>

your Bugzilla installation):

<title>Bundle::Bugzilla makes me upgrade to Perl 5.6.1</title>
<para>
Try executing <command>perl -MCPAN -e 'install CPAN'</command>
and then continuing.
</para>
<para>
Certain older versions of the CPAN toolset were somewhat naive about how
to upgrade Perl modules. When a couple of modules got rolled into the core
Perl distribution for 5.6.1, CPAN thought that the best way to get those
modules up to date was to haul down the Perl distribution itself and
build it. Needless to say, this has caused headaches for just about
everybody. Upgrading to a newer version of CPAN with the
commandline above should fix things.
