  <title>Installing Bugzilla</title>

  <section id="installation">
    <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 from
      your web browser.
      </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>

    <procedure>
      <step>
        <para><link linkend="install-perl">Install Perl</link>
        (&min-perl-ver; or above)
        </para>
      </step>
      <step>
        <para><link linkend="install-database">Install a Database Engine</link>

          <link linkend="install-MTA">Install a Mail Transfer Agent</link>
          (Sendmail 8.7 or above, or an MTA that is Sendmail-compatible with at least this version)
        </para>
      </step>
      <step>
        <para>Configure all of the above.
        </para>
      </step>
    </procedure>

    <section id="install-perl">
      <title>Perl</title>

      <para>Installed Version Test: <filename>perl -v</filename></para>
      
      <para>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 <ulink url="http://www.perl.com"/>.
      Although Bugzilla runs with Perl &min-perl-ver;,
      it's a good idea to be using the latest stable version.
      </para>
    </section>

    <section id="install-database">
      <title>Database Engine</title>
      
      <para>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.</para>

      <section id="install-mysql">
          <title>MySQL</title>
          <para>Installed Version Test: <filename>mysql -V</filename></para>
      
          <para>
          If you don't have it and your OS doesn't provide official packages, 
          visit <ulink url="http://www.mysql.com"/>. You need MySQL version
          &min-mysql-ver; or higher.
          </para>
      
          <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. To change the data
            directory, you have to build MySQL from source yourself, and
            set it as an option to <filename>configure</filename>.</para>
          </note> 
           
          <para>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.
          </para>
      </section>
      
      <section id="install-pg">
          <title>PostgreSQL</title>
          <para>Installed Version Test: <filename>psql -V</filename></para>
      
          <para>
          If you don't have it and your OS doesn't provide official packages, 
          visit <ulink url="http://www.postgresql.org/"/>. You need PostgreSQL
          version &min-pg-ver; or higher.
          </para>
           
          <para>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.
          </para>
      </section>
      
    </section>
    
    <section id="install-webserver">
      <title>Web Server</title>

      <para>Installed Version Test: view the default welcome page at
      http://&lt;your-machine&gt;/</para>
      
      <para>You have freedom of choice here, pretty much any web server that
      is capable of running <glossterm linkend="gloss-cgi">CGI</glossterm>
      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;.
      </para>
      
      <para>
      If you don't have Apache and your OS doesn't provide official packages, 
      visit <ulink url="http://httpd.apache.org/"/>.
      </para>

    </section>

    <section id="install-bzfiles">
      <title>Bugzilla</title>

      <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 web server's document directories or
        in <filename>/usr/local</filename> with a symbolic link to the web server's 
        document directories or an alias in the web server's configuration.
      </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 web server'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

      <screen><prompt>bash#</prompt> ./checksetup.pl --check-modules</screen>
 
      <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>
        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>
        The preferred way of installing Perl modules is via CPAN on Unix, 
        or PPM on Windows (see <xref linkend="win32-perl-modules"/>). 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.

      <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

      <note>
        <para>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 <filename>&lt;packagename&gt;-devel</filename>.</para>

      <para>
        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.
      </para>

      <para>
        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.
      </para>

      <para>
        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

          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.

          <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.

          <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
            accepted by Bugzilla.

          <note>
            <para>
              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.

          <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>

          <para>
            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
            <filename>localconfig</filename>; if you changed those,
            you need to modify the SQL command appropriately. You will

          <para>
            We use an SQL <command>GRANT</command> command to create

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

          <screen>

          </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>You need to add a new user to PostgreSQL for the Bugzilla

          <para>Now, you will need to edit <filename>pg_hba.conf</filename> which is

          <para>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.</para>

          <para>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 <filename>postgresql.conf</filename>. After the server has
          restarted, you will need to edit <filename>localconfig</filename>, finding
          the <literal>$db_driver</literal> variable and setting it to
          <literal>Pg</literal> and changing the password in <literal>$db_pass</literal>

    <section>

      <para>
        Next, rerun <filename>checksetup.pl</filename>. 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. 
      </para>

      <para>
        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.

        </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
          your Bugzilla installation through 
          <quote>http://&lt;yourdomainname&gt;/Bugzilla</quote>, then do
          <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:
        </para>

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

        <para>
          For example:
        </para>

        <programlisting>
c:\perl\bin\perl.exe -xc:\bugzilla -wT "%s" %s
        </programlisting>

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

        <para>
          Also, and this can't be stressed enough, make sure that files
          such as <filename>localconfig</filename> and your

        Some Bugzilla pages have alternate formats, other than just plain
        <acronym>HTML</acronym>. In particular, a few Bugzilla pages can 
        output their contents as either <acronym>XUL</acronym> (a special

  <section id="multiple-bz-dbs">
    <title>Multiple Bugzilla databases with a single installation</title>

    <para>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
      <filename>localconfig.&lt;PROJECT&gt;</filename> in the same location as
      the default one (<filename>localconfig</filename>). It also checks for
      customized templates in a directory named
      <filename>&lt;PROJECT&gt;</filename> in the same location as the
      default one (<filename>template/&lt;langcode&gt;</filename>). By default
      this is <filename>template/en/default</filename> so PROJECT's templates
      would be located at <filename>template/en/PROJECT</filename>.</para> 

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

    <para>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.
<programlisting>
&lt;VirtualHost 212.85.153.228:80&gt;
    ServerName foo.bar.baz
    SetEnv PROJECT foo
    Alias /bugzilla /var/www/bugzilla

        <para>
          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.

      <para>Making Bugzilla work on Mac OS X requires the following 
      adjustments.</para>

      <section id="macosx-sendmail">
        <title>Sendmail</title>

        <para>In Mac OS X 10.3 and later, 
        <ulink url="http://www.postfix.org/">Postfix</ulink> 
        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.</para>

        <para>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 <xref linkend="parameters"/>.</para>

      <section id="macosx-libraries">
        <title>Libraries &amp; Perl Modules on Mac OS X</title>

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

        <para>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
        <ulink url="http://sourceforge.net/projects/fink/"/>.</para>

        <para>Follow the instructions for setting up Fink. Once it's installed,
        you'll want to use it to install the <filename>gd2</filename> package.
        </para>

        <para>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 <glossterm linkend="gloss-cpan">CPAN</glossterm> to
        install the GD Perl module.
        </para>

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

        <para>Also available via Fink is <filename>expat</filename>. 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:
        </para>

        <screen>
# perl -MCPAN -e'look XML::Parser'        <co id="macosx-look"/>
# perl Makefile.PL EXPATLIBPATH=/sw/lib EXPATINCPATH=/sw/include

# exit                                    <co id="macosx-exit"/>
        </screen>
        <calloutlist>
          <callout arearefs="macosx-look macosx-exit">
            <para>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.
            </para>
          </callout>
          <callout arearefs="macosx-make">
            <para>You should watch the output from these make commands,
            especially <quote>make test</quote> as errors may prevent

      <para>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
      <xref linkend="installation" />
      first to get an idea on the installation steps required.

      <title>MySQL</title>

      <para>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.</para>

      <warning>
        <para>You may have problems trying to set up
        <command>GRANT</command> 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 <command>GRANT</command>
        command for you.</para>

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

            Build it with PREFIX set to <filename class="directory">/home/foo/mysql</filename>,
            or use pre-installed executables, specifying that you want
            to put all of the data files in <filename class="directory">/home/foo/mysql/data</filename>.
            If there is another MySQL server running on the system that you

              <para>You will need to start the daemons yourself. You can either

    <section>
      <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>

        <command>tar zvxf stable.tar.gz</command>
        <prompt>bash$</prompt>
        <command>cd perl-5.8.1</command> (or whatever the version of Perl is called)
        <prompt>bash$</prompt>
        <command>sh Configure -de -Dprefix=/home/foo/perl</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 will need to
      install the Perl Modules, described below.
      </para>
    </section>

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

      <para>
      Installing the Perl modules as a non-root user is accomplished by
      running the <filename>install-module.pl</filename>
      script. For more details on this script, see 
      <ulink url="api/install-module.html"><filename>install-module.pl</filename>
      documentation</ulink>
      </para>
    </section>

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

      <para>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.</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

    <section>
      <title>Bugzilla</title>

      <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 <xref linkend="install-perlmodules-nonroot"/>, 
      then delete the <filename>localconfig</filename> file and try again.
      </para>

      <warning>
        <para>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>
      </warning>

      <section id="suexec">
        <title>suexec or shared hosting</title>

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