    <title>Installation</title>

    <note>
      <para>If you just want to <emphasis>use</emphasis> 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 over the web.
      </para>
    </note>

    <para>The Bugzilla server software is usually installed on Linux or 
    Solaris. 
    If you are installing on another OS, check <xref linkend="os-specific"/>
    before you start your installation to see if there are any special
    instructions.
    </para>

    <para>
      As an alternative to following these instructions, you may wish to
      try Arne Schirmacher's unofficial and unsupported 
      <ulink url="http://www.softwaretesting.de/article/view/33/1/8/">Bugzilla
      Installer</ulink>, which installs Bugzilla and all its prerequisites
      on Linux or Solaris systems.
    </para>

    <para>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.
    </para>

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

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

    <para>In outline, the installation proceeds as follows:

      <para>
        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 <quote>apache</quote> or <quote>www</quote>). 
        Good locations are either directly in the main web space for your
        web server or perhaps in 
        <filename>/usr/local</filename>
        with a symbolic link from the web space.
      </para>

      <caution>
        <para>The default Bugzilla distribution is NOT designed to be placed
        in a <filename class="directory">cgi-bin</filename> directory. This
        includes any directory which is configured using the
        <option>ScriptAlias</option> directive of Apache.
        </para>
      </caution>
      
      <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 
      <filename>checksetup.pl</filename>
      script, which locks down your installation.</para>
    </section>

    <section id="install-perlmodules">
      <title>Perl Modules</title>
      
      <para>Bugzilla's installation process is based
      on a script called <filename>checksetup.pl</filename>. 
      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, 
      <emphasis>do not run it again</emphasis>, 
      but proceed to <xref linkend="configuration"/>.
      </para>
      
      <para>
      At this point, you need to <filename>su</filename> to root. You should
      remain as root until the end of the install. Then run:
      </para>
      
      <screen><prompt>bash#</prompt> ./checksetup.pl</screen>

      <!-- We really need a "module-check" switch for checksetup,
      which we can use here to make it really clear when they've got
      all the modules. -->
 
 
      <para>
        <filename>checksetup.pl</filename> 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.
      </para>
      
      <para>
        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.
      </para>
      
      <para>
        The preferred way of installing Perl modules is via CPAN on Unix, 
        or PPM on Windows (see <xref linkend="win32-perlmodules"/>). These
        instructions assume you are using CPAN; if for some reason you need 
        to install the Perl modules manually, see 
        <xref linkend="install-perlmodules-manual"/>.
      </para>  
        
      <screen><prompt>bash#</prompt> perl -MCPAN -e 'install "&lt;modulename&gt;"'</screen>

      <para>
        If you using Bundle::Bugzilla, invoke the magic CPAN command on it.
        Otherwise, you need to work down the 
        list of modules that <filename>checksetup.pl</filename> says are
        required, in the order given, invoking the command on each.
      </para>
      
      <tip>
        <para>Many people complain that Perl modules will not install for
        them. Most times, the error messages complain that they are missing a
        file in 
        <quote>@INC</quote>. 
        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 
        <emphasis>are</emphasis>
        the local UNIX sysadmin, please consult the newsgroup/mailing list
        for further assistance or hire someone to help you out.</para>

      Sendmail, Postfix, qmail and Exim are examples of common MTAs. Sendmail is the

        <para>
          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 <filename>/etc/my.cnf</filename> as below.

  # Allow packets up to 1M
  max_allowed_packet=1M</screen>

        <para>

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

        <title>Allow small words in full-text indexes</title>

        <para>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".</para>

        <para>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 <filename>/etc/my.cnf</filename>
        according to the example below:</para>

        <screen>  [mysqld]
  # Allow small words in full-text indexes
  ft_min_word_len=2</screen>

        <para>Rebuilding the indexes can be done based on documentation found at

        <title>Permit attachments table to grow beyond 4GB</title>

        <para>
          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.
        </para>

        <para>

        </screen>

        <para>
          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.

        </para>

        <para>
          You will need to create a virtual directory for the Bugzilla
          install.  Put the Bugzilla files in a directory that is named
          something <emphasis>other</emphasis> than what you want your
          end-users accessing.  That is, if you want your users to access

          <emphasis>not</emphasis> put your Bugzilla files in a directory
          named <quote>Bugzilla</quote>.  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 <quote>Execute (such as ISAPI applications or
          CGI)</quote> access permission.
        </para>

        <para>
          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:

        <programlisting>
&lt;full path to perl.exe &gt;\perl.exe -x&lt;full path to Bugzilla&gt; -wT "%s" %s

          For example:

        <note>
          <para>
            The ActiveState install may have already created an entry for

          </para>
        </note>

        <para>
          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.

      <title>The Whining Cron</title>

      <para>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.
      </para>
      <para>
        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.

          Windows does not have 'cron', but it does have the Task

      <title>LDAP Authentication</title>

      <para>LDAP authentication is a module for Bugzilla's plugin 
      authentication architecture.
      </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>

      <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

        <title>Perl Modules on Win32</title>

        <para>
          Bugzilla on Windows requires the same perl modules found in
          <xref linkend="install-perlmodules"/>. The main difference is that
          windows uses <glossterm linkend="gloss-ppm">PPM</glossterm> instead

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

<command>ppm repository add landfill http://www.landfill.bugzilla.org/ppm/</command>
        </programlisting>

          <para>
            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 <command>checksetup.pl</command> 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

      <title>Perl</title>

      <para>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:</para>

      <screen>
        <prompt>bash$</prompt>
        <command>wget http://perl.com/CPAN/src/stable.tar.gz</command>
        <prompt>bash$</prompt>
        <command>tar zvxf stable.tar.gz</command>

        <prompt>bash$</prompt>
        <command>make &amp;&amp; make test &amp;&amp; make install</command>
      </screen>

      <para>Once you have Perl installed into a directory (probably
      in <filename class="directory">~/perl/bin</filename>), you'll have to
      change the locations on the scripts, which is detailed later on
      this page.</para>
    </section>

    <section id="install-perlmodules-nonroot">
      <title>Perl Modules</title>

      <para>Installing the Perl modules as a non-root user is probably the
      hardest part of the process. There are two different methods: a
      completely independant Perl with its own modules, or personal
      modules using the current (root installed) version of Perl. The
      independant method takes up quite a bit of disk space, but is
      less complex, while the mixed method only uses as much space as the
      modules themselves, but takes more work to setup.</para>

      <section>
        <title>The Independant Method</title>

        <para>The independant method requires that you install your own
        personal version of Perl, as detailed in the previous section. Once
        installed, you can start the CPAN shell with the following
        command:</para>

        <para>
          <screen>
            <prompt>bash$</prompt>
            <command>/home/foo/perl/bin/perl -MCPAN -e 'shell'</command>
          </screen>
        </para>

        <para>And then:</para>

        <para>
          <screen>
            <prompt>cpan&gt;</prompt>
            <command>install Bundle::Bugzilla</command>
          </screen>
        </para>

        <para>With this method, module installation will usually go a lot
        smoother, but if you have any hang-ups, you can consult the next
        section.</para>
      </section>

      <section>
        <title>The Mixed Method</title>

        <para>First, you'll need to configure CPAN to
        install modules in your home directory. The CPAN FAQ says the
        following on this issue:</para>

        <para>
          <programlisting>
5)  I am not root, how can I install a module in a personal directory?

    You will most probably like something like this:

      o conf makepl_arg "LIB=~/myperl/lib \
                         INSTALLMAN1DIR=~/myperl/man/man1 \
                         INSTALLMAN3DIR=~/myperl/man/man3"
    install Sybase::Sybperl

    You can make this setting permanent like all "o conf" settings with "o conf commit".

    You will have to add ~/myperl/man to the MANPATH environment variable and also tell your Perl programs to
    look into ~/myperl/lib, e.g. by including

      use lib "$ENV{HOME}/myperl/lib";

    or setting the PERL5LIB environment variable.

    Another thing you should bear in mind is that the UNINST parameter should never be set if you are not root.</programlisting>
        </para>

        <para>So, you will need to create a Perl directory in your home
        directory, as well as the <filename class="directory">lib</filename>,
        <filename class="directory">man</filename>,
        <filename class="directory">man/man1</filename>, and
        <filename class="directory">man/man3</filename> directories in that
        Perl directory. Set the MANPATH variable and PERL5LIB variable, so
        that the installation of the modules goes smoother. (Setting
        UNINST=0 in your "make install" options, on the CPAN first-time
        configuration, is also a good idea.)</para>

        <para>After that, go into the CPAN shell:</para>

        <para>
          <screen>
            <prompt>bash$</prompt>
            <command>perl -MCPAN -e 'shell'</command>
          </screen>
        </para>

        <para>From there, you will need to type in the above "o conf" command
        and commit the changes. Then you can run through the installation:</para>

        <para>
          <screen>
            <prompt>cpan&gt;</prompt>
            <command>install Bundle::Bugzilla</command>
          </screen>
        </para>

        <para>Most of the module installation process should go smoothly. However,
        you may have some problems with Template. When you first start, you will
        want to try to install Template with the XS Stash options on. If this
        doesn't work, it may spit out C compiler error messages and croak back
        to the CPAN shell prompt. So, redo the install, and turn it off. (In fact,
        say no to all of the Template questions.) It may also start failing on a
        few of the tests. If the total tests passed is a reasonable figure (90+%),
        force the install with the following command:</para>

        <para>
          <screen>
            <prompt>cpan&gt;</prompt>
            <command>force install Template</command>
          </screen>
        </para>

        <para>You may also want to install the other optional modules:</para>

        <screen>
          <prompt>cpan&gt;</prompt>
          <command>install GD</command>
          <prompt>cpan&gt;</prompt>
          <command>install Chart::Base</command>
          <prompt>cpan&gt;</prompt>
          <command>install MIME::Parser</command>
        </screen>

      </section>
    </section>

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

      <para>Ideally, this also needs to be installed as root and
      run under a special webserver 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.</para>

      <section>
        <title>Running Apache as Non-Root</title>

        <para>You can run Apache as a non-root user, but the port will need
        to be set to one above 1024. If you type <command>httpd -V</command>,
        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.</para>

        <para>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.</para>

        <note>
          <para>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.</para>
        </note>

        <warning>
          <para>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!</para>
        </warning>
      </section>
    </section>

    <section>
      <title>Bugzilla</title>

      <para>If you had to install Perl modules as a non-root user
      (<xref linkend="install-perlmodules-nonroot" />) or to non-standard
      directories, you will need to change the scripts, setting the correct
      location of the Perl modules:</para>

      <para>
        <programlisting>perl -pi -e
        's@use strict\;@use strict\; use lib \"/home/foo/perl/lib\"\;@'
        *cgi *pl Bug.pm processmail syncshadowdb</programlisting>

        Change <filename class="directory">/home/foo/perl/lib</filename> to
        your personal Perl library directory. You can probably skip this
        step if you are using the independant method of Perl module
        installation.
      </para>

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

      <warning>
        <para>The one option in <filename>localconfig</filename> you
        might have problems with is the web server group. If you can't
        successfully browse to the <filename>index.cgi</filename> (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.</para>
