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,

REQUIRED PACKAGES:
------------------

o   Perl 5.8.3 or later (http://www.perl.com).

       Perl versions prior to 5.8.3 contain bugs that could result
       in data corruption. We recommend strongly that you use 5.8.3
       or newer.

o   A supported SQL database

        Currently supported:  Mysql 4.0.13 or later with InnoDB support.
                              Postgres 7.2 or later.
                              Oracle 9iR2 or later.
                              SQLite 3.0. (Not recommended for production)

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

        Compiling mod_perl on Apache 1.3.x as a DSO has been known 
        to have massive stability problems and is not recommended.

        mod_perl 1.x must be built with EVERYTHING=1

        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 system
	(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
--------------------

This is a rough guide to installing RT. For more detail, you'll
want to read a more comprehensive installation guide at:

    http://wiki.bestpractical.com/index.cgi?InstallationGuides

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. 

       ./configure --help to see the list of options
       ./configure (with the flags you want)

    RT defaults to installing in /opt/rt3 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.

3   Make sure that RT has everything 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

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.

6   If this is a new installation:
     
     As a user with permission to install RT in your chosen directory, type:

       make install   
                    
     Set up 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 start over from step 6

7   If you're upgrading from RT 3.0 or newer:

     Read through the UPGRADING document included in this distribution.
     
     It includes special upgrade instructions that will help you get this
     new version of RT up and running smoothly.

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

       make upgrade    

     This will install new binaries, config files and libraries without
     overwriting your RT database. 

     Update etc/RT_SiteConfig.pm in your RT installation directory.
     You'll need to add any new values you need to change from the defaults 
     in etc/RT_Config.pm

     You may also need to update RT's database.  To find out, type:

       ls etc/upgrade

     For each item in that directory whose name is greater than
     your previously installed RT version, run:

       /opt/rt3/sbin/rt-setup-database --action schema \
           --datadir etc/upgrade/<version>
       /opt/rt3/sbin/rt-setup-database --action acl \
           --datadir etc/upgrade/<version>
       /opt/rt3/sbin/rt-setup-database --action insert \
            --datadir etc/upgrade/<version>

     Clear mason cache dir:

       rm -fr /opt/rt3/var/mason_data/obj

     Stop and start web-server.


8  If you're upgrading from RT 2.0:

    Please upgrade from RT 2.0 to RT 3.2 and then follow the instructions
    for section 7.

9   Configure the email and web gateways, as described below. 

    NOTE: root's password for the web interface is "password" 
    (without the quotes).  Not changing this is a SECURITY risk!
    
10   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.


SETTING UP THE WEB INTERFACE
----------------------------

RT's web interface is based around HTML::Mason, which works well with
the mod_perl perl interpreter within Apache httpd and FastCGI

mod_perl
--------

To install RT with mod_perl, you'll need to install the
apache database connection cache.  To make sure it's installed, run
the following command:

    perl -MCPAN -e'install Apache::DBI'

Next, add a few lines to your Apache configuration file, so that
it knows where to find RT:

<VirtualHost your.ip.address>
    ServerName your.rt.server.hostname
    DocumentRoot /opt/rt3/share/html
    AddDefaultCharset UTF-8

    PerlModule Apache::DBI
    PerlRequire /opt/rt3/bin/webmux.pl

    <Location />
     SetHandler perl-script
     PerlHandler RT::Mason
    </Location>
</VirtualHost>

FastCGI
-------

Installation with FastCGI is a little bit more complex and is documented 
in detail at http://wiki.bestpractical.com/index.cgi?FastCGIConfiguration

In the most basic configuration, you can set up your webserver to run
as a user who is a member of the "rt" unix group so that the FastCGI script
can read RT's configuration file.  It's important to understand the security
implications of this configuration, which are discussed in the document
mentioned above.

To install RT with FastCGI, you'll need to add a few lines to your 
Apache configuration file telling it about RT:


# Tell FastCGI to put its temporary files somewhere sane.
FastCgiIpcDir /tmp

FastCgiServer /opt/rt3/bin/mason_handler.fcgi -idle-timeout 120

<VirtualHost rt.example.com>

   # Pass through requests to display images
   Alias /NoAuth/images/ /opt/rt3/share/html/NoAuth/images/

   AddHandler fastcgi-script fcgi
   ScriptAlias / /opt/rt3/bin/mason_handler.fcgi/
   
</VirtualHost>



SETTING UP THE MAIL 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/rt3/bin/rt-mailgate --queue general --action correspond --url http://rt.example.com/"
rt-comment: "|/opt/rt3/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/rt3/bin/rt-mailgate



GETTING HELP
------------

If RT is mission-critical for you or if you use it heavily, we recommend that
you purchase a commercial support contract.  Details on support contracts
are available at http://www.bestpractical.com or by writing to
<sales@bestpractical.com>.

If you're interested in having RT extended or customized or would like more
information about commercial support options, please send email to 
<sales@bestpractical.com> to discuss rates and availability.



RT WEBSITE
----------

For current information about RT, check out the RT website at 
     http://www.bestpractical.com/  

You'll find screenshots, a pointer to the current version of RT, contributed 
patches, and lots of other great stuff.



RT-USERS MAILING LIST
--------------------

To keep up to date on the latest RT tips, techniques and extensions,
you probably want to join the rt-users mailing list.  Send a message to:

      rt-users-request@lists.bestpractical.com 

with the body of the message consisting of only the word:

     subscribe

If you're interested in hacking on RT, you'll want to subscribe to
<rt-devel@lists.bestpractical.com>.  Subscribe to it with instructions
similar to those above.

Address questions about the stable release to the rt-users list, and
questions about the development version to the rt-devel list.  If you feel
your questions are best not asked publicly, send them personally to
<jesse@bestpractical.com>.



BUGS
----

RT's a pretty complex application, and as you get up to speed, you might
run into some trouble. Generally, it's best to ask about things you
run into on the rt-users mailinglist (or pick up a commercial support
contract from Best Practical). But, sometimes people do run into bugs. In
the exceedingly unlikely event that you hit a bug in RT, please report
it! We'd love to hear about problems you have with RT, so we can fix them.
To report a bug, send email to rt-bugs@fsck.com.
