Upgrade to 4.2.2

[usit-rt.git] / docs / README

RT is an enterprise-grade issue tracking system. It allows organizations
to keep track of what needs to get done, who is working on which tasks,
what's already been done, and when tasks were (or weren't) completed.

RT doesn't cost anything to use, no matter how much you use it; it is
freely available under the terms of Version 2 of the GNU General Public
License.

RT is commercially-supported software. To purchase support, training,
custom development, or professional services, please get in touch with
us at <sales@bestpractical.com>.


REQUIRED PACKAGES
-----------------

o   Perl 5.10.1 or later (http://www.perl.org).

        RT won't start on versions of Perl older than 5.10.1.

o   A supported SQL database

        Currently supported:  MySQL 5.1 or later with InnoDB support.
                              Postgres 8.4 or later; 9.0 or later suggested
                              Oracle 9iR2 or later.
                              SQLite 3.0 or later; for testing only, no
                                           upgrade path guaranteed

o   Apache version 1.3.x or 2.x (http://httpd.apache.org)
        with mod_perl -- (http://perl.apache.org)
        or with FastCGI -- (www.fastcgi.com)
        or other webserver with FastCGI support

        RT's FastCGI handler needs to access RT's configuration file.

o   Various and sundry perl modules

        A tool included with RT takes care of the installation of most
        of these automatically during the install process.

        The tool supplied with RT uses Perl's CPAN (http://www.cpan.org)
        to install modules. Some operating systems package all or some
        of the modules required, and you may be better off installing
        the modules that way.


GENERAL INSTALLATION
--------------------

 1) Unpack this distribution other than where you want to install RT.
    To do this cleanly, run the following command:

        tar xzvf rt.tar.gz -C /tmp

 2) Run the "configure" script.  To see the list of options, run:

        ./configure --help

    Peruse the options, then rerun ./configure with the flags you want.

    RT defaults to installing in /opt/rt4 with MySQL as its database. It
    tries to guess which of www-data, www, apache or nobody your
    webserver will run as, but you can override that behavior.  Note
    that the default install directory in /opt/rt4 does not work under
    SELinux's default configuration.

    If you are upgrading from a previous version of RT, please review
    the upgrade notes for the appropriate versions, which can be found
    in docs/UPGRADING-* If you are coming from 3.8.6 to 4.0.x you should
    review both the UPGRADING-3.8 and UPGRADING-4.0 file.  Similarly, if
    you were coming from 3.6.7, you would want to review UPGRADING-3.6,
    UPGRADING-3.8 and UPGRADING-4.0

    It is particularly important that you read the warnings at the top of
    UPGRADING-4.0 for some common issues.

    RT stores the arguments given to ./configure at the top of the
    etc/RT_Config.pm file in case you need to recreate your previous use
    of ./configure.

 3) Make sure that RT has the Perl and system libraries it needs to run.
    Check for missing dependencies by running:

        make testdeps

 4) If the script reports any missing dependencies, install them by
    hand, or run the following command as a user who has permission to
    install perl modules on your system:

        make fixdeps

    Some modules require user input or environment variables to install
    correctly, so it may be necessary to install them manually.

    If you are installing with CPAN module older than 1.84, you will
    need to start CPAN (by running perl -MCPAN -e shell) and upgrade the
    CPAN shell with:

        install CPAN

    If you are unsure of your CPAN version, it will be printed when you
    run the shell.

    If you are having trouble installing GD, refer to "Installing GD libraries"
    in docs/charts.pod.  Ticket relationship graphing requires the graphviz
    library which you should install using your distribution's package manager.

 5) Check to make sure everything was installed properly.

        make testdeps

    It might sometimes be necessary to run "make fixdeps" several times
    to install all necessary perl modules.

6a) If this is a NEW installation (not an upgrade):

      As a user with permission to install RT in your chosen directory,
      type:

          make install

      To configure RT with the web installer, run:

          /opt/rt4/sbin/rt-server

      and follow the instructions.  Once completed, you should now have a
      working RT instance running with the standalone rt-server.  Press
      Ctrl-C to stop it, and proceed to Step 7 to configure a recommended
      deployment environment for production.

      To configure RT manually, you must setup etc/RT_SiteConfig.pm in
      your RT installation directory.  You'll need to add any values you
      need to change from the defaults in etc/RT_Config.pm

      As a user with permission to read RT's configuration file, type:

          make initialize-database

      If the make fails, type:

          make dropdb

      and re-run 'make initialize-database'.

6b) If you are UPGRADING from a previous installation:

      Before upgrading, always ensure that you have a complete current
      backup. If you don't have a current backup, upgrading your database
      could accidentally damage it and lose data, or worse.

      If you are using MySQL, please read the instructions in
      docs/UPGRADING.mysql as well to ensure that you do not corrupt
      existing data.

      First, stop your webserver.  You may also wish to put incoming email
      into a hold queue, to avoid temporary delivery failure messages if
      your upgrade is expected to take several hours.

      Next, install new binaries, config files and libraries by running:

          make upgrade

      This will also prompt you to upgrade your database by running:

          make upgrade-database

      You should back up your database before running this command.
      When you run it, you will be prompted for your previous version of
      RT (such as 3.6.4) so that the appropriate set of database
      upgrades can be applied.

      Finally, clear the Mason cache dir:

          rm -fr /opt/rt4/var/mason_data/obj

      You may then start your web server again.

 7) Configure the web server, as described in docs/web_deployment.pod,
    and the email gateway, as described below.

    NOTE: The default credentials for RT are:
        User: root
        Pass: password
    Not changing the root password from the default is a SECURITY risk!

    Once you've set up the web interface, consider setting up automatic
    logout for inactive sessions. For more information about how to do
    that, run:

        perldoc /path/to/rt/sbin/rt-clean-sessions

 8) Set up users, groups, queues, scrips and access control.

    Until you do this, RT will not be able to send or receive email, nor
    will it be more than marginally functional.  This is not an optional
    step.

 9) Set up automated recurring tasks (cronjobs):

    To generate email digest messages, you must arrange for the provided
    utility to be run once daily, and once weekly. You may also want to
    arrange for the rt-email-dashboards utility to be run hourly.  For
    example, if your task scheduler is cron, you can configure it as
    follows:

        crontab -e    # as the RT administrator (probably root)
        # insert the following lines:
        0 0 * * * /opt/rt4/sbin/rt-email-digest -m daily
        0 0 * * 0 /opt/rt4/sbin/rt-email-digest -m weekly
        0 * * * * /opt/rt4/sbin/rt-email-dashboards

10) Configure the RT email gateway.  To let email flow to your RT
    server, you need to add a few lines of configuration to your mail
    server's "aliases" file. These lines "pipe" incoming email messages
    from your mail server to RT.

    Add the following lines to /etc/aliases (or your local equivalent)
    on your mail server:

        rt:         "|/opt/rt4/bin/rt-mailgate --queue general --action correspond --url http://rt.example.com/"
        rt-comment: "|/opt/rt4/bin/rt-mailgate --queue general --action comment --url http://rt.example.com/"

    You'll need to add similar lines for each queue you want to be able to
    send email to. To find out more about how to configure RT's email
    gateway, type:

           perldoc /opt/rt4/bin/rt-mailgate
