## REQUIRED PACKAGES

- Perl 5.10.1 or later ([http://www.perl.org](http://www.perl.org)).
    - RT won't start on versions of Perl older than 5.10.1.

- A supported SQL database
   - MySQL 5.7, 8 with InnoDB support
   - MariaDB 10.2 or later with InnoDB support
   - Postgres 9.5 or later
   - Oracle 12c or later
   - SQLite 3.0 or later (for testing only, no upgrade path guaranteed)

- A webserver with FastCGI or mod_perl support
    - Apache version 2.x ([https://httpd.apache.org](https://httpd.apache.org))
      - with mod_fcgid -- ([https://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html](https://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html))
      - or mod_perl -- ([http://perl.apache.org](http://perl.apache.org))
    - nginx -- ([https://nginx.org/](https://nginx.org/))
    - Another webserver with FastCGI support

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

- Various and sundry perl modules
    - A tool included with RT takes care of the installation of most of these automatically using Perl's CPAN ([http://www.cpan.org](http://www.cpan.org)). Some operating systems package all or some of the modules required, and you may be better off installing the modules that way.

## OPTIONAL DEPENDENCIES

- Full-text indexing support in your database
    - The databases listed above all have options for full-text indexing (excluding SQLite). See [docs/full_text_indexing.pod](https://docs.bestpractical.com/rt/latest/full_text_indexing.html) for details.
- An external HTML converter
    - Installing an external utility to convert HTML can improve performance. See the $HTMLFormatter configuration option for details.

- A TLS certificate for your web server
    - For production use, we recommend getting an SSL certificate for your web server. You can get them free from Let's Encrypt ([https://letsencrypt.org/](https://letsencrypt.org/)) or even create your own self-signed certificate.
    - If you are testing and want to run without a certificate, add this to your etc/RT_SiteConfig.pm file:
      ```
      Set( $WebSecureCookies, 0 );
      ```
    - Without this setting, your browser won't trust RT's cookies and you won't be able to log in. See
    [etc/RT_Config.html#WebSecureCookies](https://docs.bestpractical.com/rt/latest/RT_Config.html#WebSecureCookies) for more information.


## GENERAL INSTALLATION

1. **Unpack this distribution other than where you want to install RT.** Your home directory or `/usr/local/src` are both fine choices. Change to that directory and run the following command:
   ```
   tar xzvf rt.tar.gz
   ```

2. **Run the `configure` script.** To see the list of options, run:
   ```
   ./configure --help
   ```
   Or review the options on our [documentation page for configure](https://docs.bestpractical.com/rt/latest/configure.html).

   Then re-run `./configure` with the flags you want.

   RT defaults to installing in `/opt/rt5`. 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/rt5` does not work under
   SELinux's default configuration.

   The default database type (--with-db-type) is `mysql`, which means
   MySQL version 8 and later. Starting in RT 5.0.6, use `mysql5` to run
   MySQL 5.7 or older, and use `MariaDB` to run with MariaDB.

   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 upgrading from 4.4.x to 5.0.x you should review both the [UPGRADING-4.4](https://docs.bestpractical.com/rt/latest/UPGRADING-4.4.html) and [UPGRADING-5.0](https://docs.bestpractical.com/rt/latest/UPGRADING-5.0.html) files.

   if you are upgrading from 4.2.x, you should review
   [UPGRADING-4.2](https://docs.bestpractical.com/rt/latest/UPGRADING-4.2.html) as well.

   Any upgrade steps given in version-specific `UPGRADING` files should
   be run after the rest of the steps below; however, please read the
   relevant documentation before beginning the upgrade, so as to be
   aware of important changes.

   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. Some modules
   also require external source libraries, so you may need to install
   additional packages.

   If you are having trouble installing GD, refer to "Installing GD libraries"
   in [docs/charts.pod](https://docs.bestpractical.com/rt/latest/charts.html).
   Ticket relationship graphing requires the graphviz
   library which you should install using your distribution's package manager.

   See [docs/rt_perl.pod](https://docs.bestpractical.com/rt/latest/rt_perl.html)
   for additional information about installing perl and RT's dependencies.

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 you are installing RT for the first time

   As a user with permission to install RT in your chosen directory, type:
   ```
   make install
   ```
   To configure RT with the web installer, run:
   ```
   /opt/rt5/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 an older release of RT
   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](https://docs.bestpractical.com/rt/latest/UPGRADING.mysql.html)
   as well to ensure that you do not corrupt existing data.

   - 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.

   - Back up your database, as the next step may make changes to your database's schema and data.

   - 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
   ```

   When you run it, you will be prompted for your previous version of
   RT (such as 4.4.1) so that the appropriate set of database
   upgrades can be applied.

   If `make upgrade-database` completes without error, your upgrade
   has been successful; you should now run any commands that were
   supplied in version-specific UPGRADING documentation. You should
   then restart your webserver.

   Depending on the size and composition of your database, some upgrade
   steps may run for a long time. You may also need extra disk space or
   other resources while running upgrade steps. It's a good idea to run
   through the upgrade steps on a test server so you know what to expect
   before running on your production system.


7. Configure the web server, as described in [docs/web_deployment.pod](https://docs.bestpractical.com/rt/latest/web_deployment.html),
    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!*

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):

    Depending on your configuration, RT stores sessions in the database
    or on the file system. In either case, sessions are only needed until
    a user logs out, so old sessions should be cleaned up with the
    [`sbin/rt-clean-sessions`](https://docs.bestpractical.com/rt/latest/rt-clean-sessions.html) utility.

    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 [`sbin/rt-email-dashboards`](https://docs.bestpractical.com/rt/latest/rt-email-dashboards.html) utility to be run hourly.

    RT automatically creates temporary short URLs for searches and these
    can be cleared from the system periodically as well. See the documentation
    for the [`sbin/rt-clean-shorteners`](https://docs.bestpractical.com/rt/latest/rt-clean-shorteners.html)
    tool for options. You can schedule this to run regularly if desired.

    RT provides an interface for running scheduled jobs to automate
    some tasks, like resolving tickets after some period of time.
    To enable this, schedule [`bin/rt-run-scheduled-processes`](https://docs.bestpractical.com/rt/latest/rt-run-scheduled-processes.html)
    to run every 15 minutes.

    If your task scheduler is cron, you can configure it by
    adding the following lines as `/etc/cron.d/rt`:

    ```
        0    0 * * * root /opt/rt5/sbin/rt-clean-sessions
        0    0 * * * root /opt/rt5/sbin/rt-email-digest -m daily
        0    0 * * 0 root /opt/rt5/sbin/rt-email-digest -m weekly
        0    * * * * root /opt/rt5/sbin/rt-email-dashboards
        */15 * * * * root /opt/rt5/bin/rt-run-scheduled-processes
    ```

    Other optional features like full text search indexes, external
    attachments, etc., may also have recurring jobs to schedule in cron.
    Follow the documentation for these features when you enable them.

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/rt5/bin/rt-mailgate --queue general --action correspond --url http://rt.example.com"
    rt-comment: "|/opt/rt5/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, see [`bin/rt-mailgate`](https://docs.bestpractical.com/rt/latest/rt-mailgate.html).

11. Set up full text search

    Full text search (FTS) without database indexing is a very slow operation,
    and is thus disabled by default. You'll need to follow the instructions in
    [docs/full_text_indexing.pod](https://docs.bestpractical.com/rt/latest/full_text_indexing.html) to enable FTS.

12. Set up automatic backups for RT and its data as described in
    [docs/system_administration/database.pod](https://docs.bestpractical.com/rt/latest/system_administration/database.html).
