      <para>Bugzilla has been successfully installed under Solaris, Linux,
      and Win32. Win32 is not yet officially supported, but many people
      have got it working fine.
      Please see the 
      <xref linkend="win32" />
      for further advice on getting Bugzilla to work on Microsoft
      Windows.</para>

      <warning>
        <para>It is a good idea, while installing Bugzilla, to ensure that there
        is some kind of firewall between you and the rest of the Internet,
        because 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>

      <note>
        <para>Linux-Mandrake 8.0 includes every
        required and optional library for Bugzilla. The easiest way to
        install them is by using the 
        <filename>urpmi</filename>

        utility. If you follow these commands, you should have everything you
        need for Bugzilla, and 
        <filename>checksetup.pl</filename>

        should not complain about any missing libraries. You may already have
        some of these installed.</para>

      <title>MySQL</title>

      <para>Visit the MySQL homepage at 
      <ulink url="http://www.mysql.com">www.mysql.com</ulink>
      to grab and install the latest stable release of the server. 
      </para>
      
      <note>
        <para> Many of the binary
        versions of MySQL store their data files in 
        <filename>/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 an RPM or Debian 
      package, you will need to add <filename>mysqld</filename>
      to your init scripts so the server daemon will come back up whenever
      your machine reboots. Further discussion of UNIX init sequences are
      beyond the scope of this guide. 
      </para>

      <para>Change your init script to start 
      <filename>mysqld</filename>
      with the ability to accept large packets. By default, 
      <filename>mysqld</filename>
      only accepts packets up to 64K long. This limits the size of
      attachments you may put on bugs. If you add 
      <option>-O max_allowed_packet=1M</option>
      to the command that starts 
      <filename>mysqld</filename>
      (or <filename>safe_mysqld</filename>), 
      then you will be able to have attachments up to about 1 megabyte.
      There is a Bugzilla parameter for maximum attachment size;
      you should configure it to match the value you choose here.</para>

      <para>If you plan on running Bugzilla and MySQL on the same machine,
      consider using the 
      <option>--skip-networking</option>
      option in the init script. This enhances security by preventing
      network access to MySQL.</para>

      <title>Perl</title>

      <para>Any machine that doesn't have Perl on it is a sad machine indeed.
      Perl can be got in source form from 
      <ulink url="http://www.perl.com">perl.com</ulink> for the rare 
      *nix systems which don't have it. 
      Although Bugzilla runs with all post-5.005
      versions of Perl, 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 &perl-ver;.</para>

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

    <section>
      <title>DBI</title>
        
      <para>The DBI module is a generic Perl module used the
      MySQL-related modules. As long as your Perl installation was done
      correctly the DBI module should be a breeze. It's a mixed Perl/C
      module, but Perl's MakeMaker system simplifies the C compilation
      greatly.</para>
    </section>

    <section>
      <title>Data::Dumper</title>

      <para>The Data::Dumper module provides data structure persistence for
      Perl (similar to Java's serialization). It comes with later
      sub-releases of Perl 5.004, but a re-installation just to be sure it's
      available won't hurt anything.</para>
    </section>

    <section>
      <title>MySQL-related modules</title>

      <para>The Perl/MySQL interface requires a few mutually-dependent Perl
      modules. These modules are grouped together into the the
      Msql-Mysql-modules package.</para> 

      <para>The MakeMaker 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.</para>

      <para>A host of 'localhost' should be fine and a testing user of 'test'
      with a null password should find itself with sufficient access to run
      tests on the 'test' database which MySQL created upon installation.
      </para>
    </section>

    <section>
      <title>TimeDate modules</title>

      <para>Many of the more common date/time/calendar related Perl modules
      have been grouped into a bundle similar to the MySQL modules bundle.
      This bundle is stored on the CPAN under the name TimeDate. 
      The component module we're most interested in is the Date::Format
      module, but installing all of them is probably a good idea anyway.
      </para>
    </section>

    <section>
      <title>GD (optional)</title>

      <para>The GD library was written by Thomas Boutell a long while ago to
      programatically generate images in C. Since then it's become the
      defacto standard for programatic image construction. The Perl bindings
      to it found in the GD library are used on millions of web pages to
      generate graphs on the fly. That's what Bugzilla will be using it for
      so you must install it if you want any of the graphing to work.</para>

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

    <section>
      <title>Chart::Base (optional)</title>

      <para>The Chart module provides Bugzilla with on-the-fly charting
      abilities. It can be installed in the usual fashion after it has been
      fetched from CPAN. 
      Note that earlier versions that 0.99c used GIFs, which are no longer
      supported by the latest versions of GD.</para>
    </section>
    
    <section>
      <title>Template Toolkit</title>

      <para>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.  However, there are
      known problems with XS Stash and Perl 5.005_02 and lower.  If you
      wish to use these older versions of Perl, please use the regular
      stash.</para>

    <section>
      <title>HTTP Server</title>

      <para>You have a freedom of choice here - Apache, Netscape or any other
      server on UNIX would do. You can run the web server on a
      different machine than MySQL, but need to adjust the MySQL 
      <quote>bugs</quote>
      user permissions accordingly. 
      <note>
        <para>We strongly recommend Apache as the web server to use. The
        Bugzilla Guide installation instructions, in general, assume you are
        using Apache. If you have got Bugzilla working using another webserver,
        please share your experiences with us.</para>
      </note>
      </para>

      <para>You'll want to make sure that your web server will run any file
      with the .cgi extension as a CGI and not just display it. If you're
      using Apache that means uncommenting the following line in the httpd.conf
      file: 
      <programlisting>AddHandler cgi-script .cgi</programlisting>
      </para>

      <para>With Apache you'll also want to make sure that within the
      httpd.conf file the line: 
      <programlisting>Options ExecCGI AllowOverride Limit</programlisting>

      is in the stanza that covers the directories into which you intend to
      put the bugzilla .html and .cgi files.

        <note>
          <para>AllowOverride Limit allows the use of a Deny statement in the
          .htaccess file generated by checksetup.pl</para>

          <para>Users of older versions of Apache may find the above lines 
          in the srm.conf and access.conf files, respecitvely.</para>
        </note>
      </para>
      
      <warning>
        <para>There are important files and directories that should not be a
        served by the HTTP server - most files in the 
        <quote>data</quote>
        and 
        <quote>shadow</quote>
        directories and the 
        <quote>localconfig</quote>
        file. You should configure your HTTP server to not serve 
        these files. Failure to do so will expose critical passwords and
        other data. Please see 
        <xref linkend="htaccess" />
        for details on how to do this for Apache; the checksetup.pl
        script should create appropriate .htaccess files for you.</para>
      </warning>
    </section>

    <section>
      <title>Bugzilla</title>

      <para>You should untar the Bugzilla files into a directory that you're
      willing to make writable by the default web server user (probably 
      <quote>nobody</quote>). 
      You may decide to put the files in the main web space for your
      web server or perhaps in 
      <filename>/usr/local</filename>
      with a symbolic link in the web space that points to the Bugzilla
      directory.</para>

      <tip>
        <para>If you symlink the bugzilla directory into your Apache's HTML
        heirarchy, you may receive 
        <errorname>Forbidden</errorname>
        errors unless you add the 
        <quote>FollowSymLinks</quote>
        directive to the &lt;Directory&gt; entry for the HTML root
        in httpd.conf.</para>
      </tip>

      <para>Once all the files are in a web accessible directory, make that
      directory writable by your webserver's user. This is a temporary step
      until you run the post-install 
      <filename>checksetup.pl</filename>
      script, which locks down your installation.</para>

      <para>Lastly, you'll need to set up a symbolic link to 
      <filename>/usr/bonsaitools/bin/perl</filename>
      for the correct location of your Perl executable (probably 
      <filename>/usr/bin/perl</filename>). 
      Otherwise you must hack all the .cgi files to change where they look
      for Perl. This can be done using the following Perl one-liner, but 
      I suggest using the symlink approach to avoid upgrade hassles.
      </para>
      
      <para> 
        <programlisting>perl -pi -e
        's@#\!/usr/bonsaitools/bin/perl@#\!/usr/bin/perl@' *cgi *pl Bug.pm

      <title>Setting Up the MySQL Database</title>

      <para>After you've gotten all the software installed and working you're
      ready to start preparing the database for its life as the back end to
      a high quality bug tracker.</para>

      <para>First, you'll want to fix MySQL permissions to allow access from
      Bugzilla. For the purpose of this Installation section, the Bugzilla
      username will be 
      <quote>bugs</quote>, and will have minimal permissions. 
      </para>

      <para>Begin by giving the MySQL root user a password. MySQL passwords are limited
      to 16 characters. 
      <simplelist>
        <member>
          <computeroutput>
            <prompt>bash#</prompt>

            <command>mysql -u root mysql</command>
          </computeroutput>
        </member>

        <member>
          <computeroutput>
            <prompt>mysql&gt;</prompt>

            <command>UPDATE user SET Password=PASSWORD('&lt;new_password'&gt;)
            WHERE user='root';</command>
          </computeroutput>
        </member>

        <member>
          <computeroutput>
            <prompt>mysql&gt;</prompt>

            <command>FLUSH PRIVILEGES;</command>
          </computeroutput>
        </member>
      </simplelist>

      From this point on, if you need to access MySQL as the MySQL root user,
      you will need to use 
      <command>mysql -u root -p</command>

      and enter &lt;new_password&gt;. Remember that MySQL user names have
      nothing to do with Unix user names (login names).</para>

      <para>Next, we use an SQL <command>GRANT</command> command to create a 
      <quote>bugs</quote>

      user, and grant sufficient permissions for checksetup.pl, which we'll
      use later, to work its magic. This also restricts the 
      <quote>bugs</quote>
      user to operations within a database called 
      <quote>bugs</quote>, and only allows the account to connect from 
      <quote>localhost</quote>. 
      Modify it to reflect your setup if you will be connecting from
      another machine or as a different user.</para>

      <para>Remember to set &lt;bugs_password&gt; to some unique password.

      <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 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. 
      <simplelist>
        <member>

            <command>./checksetup.pl</command>
          </computeroutput>
        </member>
      </simplelist>

      The first time you run it, it will create a file called 
      <filename>localconfig</filename>.</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>
        <listitem>
          <para>server's host: just use 
          <quote>localhost</quote>

          <para>database name:

          <para>Password for the

          MySQL account; (&lt;bugs_password&gt;) 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>

      <note>
        <para>The checksetup.pl script is designed so that you can run it at
        any time without causing harm. You should run it after any upgrade to
        Bugzilla.</para>

      <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 
            <ulink url="http://www.graphviz.org/">GraphViz</ulink>) 
            will generate the graphs locally
            </para>
          </listitem>
          <listitem>
            <para>
            A URL prefix pointing to an installation of the webdot package will

          <listitem>
            <para>

      server-side image maps</ulink> in Apache.
      Alternatively, you could set up a webdot server, or use the AT&amp;T 
      public webdot server (the
      default for the webdotbase param). Note that AT&amp;T's server won't work
      if Bugzilla is only accessible using HTTPS.

      <title>The Whining Cron</title>

      <para>By now you have a fully functional Bugzilla, but what good are
      bugs if they're not annoying? To help make those bugs more annoying you
      can set up Bugzilla's automatic whining system to complain at engineers
      which leave their bugs in the NEW state without triaging them.
      </para>
      <para>
      This can be done by
      adding the following command as a daily crontab entry (for help on that
      see that crontab man page):

      <title>LDAP Authentication</title>
      <para>
        <warning>
          <para>This information on using the LDAP
            authentication options with Bugzilla is old, and the authors do
            not know of anyone who has tested it. Approach with caution.
          </para>
        </warning>
      </para>
      
      <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>
      
      <para>Using LDAP for Bugzilla authentication requires the 
      Mozilla::LDAP (aka PerLDAP) Perl module. The
      Mozilla::LDAP module in turn requires Netscape's Directory SDK for C.
      After you have installed the SDK, then install the PerLDAP module.
      Mozilla::LDAP and the Directory SDK for C are both 
      <ulink url="http://www.mozilla.org/directory/">available for
      download</ulink> from mozilla.org. 
      </para>
      
      <para>
      Set the Param 'useLDAP' to "On" **only** if you will be using an LDAP
      directory for
      authentication. Be very careful when setting up this parameter; if you
      set LDAP authentication, but do not have a valid LDAP directory set up,
      you will not be able to log back in to Bugzilla once you log out. (If
      this happens, you can get back in by manually editing the data/params
      file, and setting useLDAP back to 0.)
      </para>
      
      <para>If using LDAP, you must set the
      three additional parameters: Set LDAPserver to the name (and optionally
      port) of your LDAP server. If no port is specified, it defaults to the
      default port of 389. (e.g "ldap.mycompany.com" or
      "ldap.mycompany.com:1234") Set LDAPBaseDN to the base DN for searching
      for users in your LDAP directory. (e.g. "ou=People,o=MyCompany") uids
      must be unique under the DN specified here. Set LDAPmailattribute to
      the name of the attribute in your LDAP directory which contains the
      primary email address. On most directory servers available, this is
      "mail", but you may need to change this.

      <para>It is possible for a Bugzilla to execute malicious Javascript

      Executing the following code snippet from a UNIX command shell will
      rectify the problem if your Bugzilla installation is intended for an
      English-speaking audience. As always, be sure your Bugzilla
      installation has a good backup before making changes, and I recommend

    <para>This section covers installation on Microsoft Windows. 
    Bugzilla has been made to work on Win32 platforms, but the Bugzilla team
    wish to emphasise that The easiest way to install Bugzilla on
    Intel-archiecture machines
    is to install some variant of GNU/Linux, then follow the UNIX
    installation instructions in this Guide. If you have any influence in the
    platform choice for running this system, please choose GNU/Linux instead
    of Microsoft Windows.</para>

    <warning>
      <para>After that warning, here's the situation for 2.16
      and Windows. It doesn't work at all out of the box. 
      You are almost certainly better off getting
      the 2.17 version from CVS (after consultation with the Bugzilla Team to
      make sure you are pulling on a stable day) because we'll be doing a load
      of work to make the Win32 experience more pleasant than it is now.
      </para>
    </warning>

    <para>
    If you still want to try this, to have any hope of getting it to work,
    you'll need to apply the 
    <ulink url="">mail patch</ulink> from 
    <ulink url="http://bugzilla.mozilla.org/show_bug.cgi?id=124174">bug 124174</ulink>.
    After that, you'll need to read the (outdated) installation 
    instructions below, some (probably a lot better) <ulink url="http://bugzilla.mozilla.org/attachment.cgi?id=84430&amp;action=view">more
     recent ones</ulink> kindly provided by Toms Baugis and Jean-Sebastien

     we'll write some better installation instructions for 2.16 and put
     them up there. But no promises.

    <title>Mac OS X Installation Notes</title>

    <para>There are a lot of common libraries and utilities out there that
    Apple did not include with Mac OS X, but which run perfectly well on it.
    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
    &lt;http://sourceforge.net/projects/fink/&gt;.</para>

    <para>Follow the instructions for setting up Fink. Once it's installed,
    you'll want to run the following as root: 
    <command>fink install gd</command>
    </para>

    <para>It will prompt you for a number of dependencies, type 'y' and hit
    enter to install all of the dependencies. Then watch it work.</para>

    <para>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 for libgd will be at /sw/lib and /sw/include instead of /usr/lib
    and /usr/local/include. Because of these changed locations for the
    libraries, the Perl GD module will not install directly via CPAN, because it
    looks for the specific paths instead of getting them from your
    environment. But there's a way around that :-)</para>

    <para>Instead of typing 
    <quote>install GD</quote>
    at the 
    <prompt>cpan&gt;</prompt>
    prompt, type 
    <command>look GD</command>. 
    This should go through the motions of downloading the latest version of
    the GD module, then it will open a shell and drop you into the build
    directory. Apply <ulink url="../sgml/gd-makefile.patch">this patch</ulink> 
    to the Makefile.PL file (save the
    patch into a file and use the command 
    <command>patch &lt; patchfile</command>.)

    <para>Then, run these commands to finish the installation of the GD

      <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.
