[[TracGuideToc]]

Trac is a lightweight project management tool that is implemented as a web-based application. Trac is written in the Python programming language and can use [http://sqlite.org/ SQLite] or [http://www.postgresql.org/ PostgreSQL] as  database. For HTML rendering, Trac uses the [http://www.clearsilver.net/ Clearsilver] templating system.

What follows are generic instructions for installing and setting up Trac and its requirements. While you can find instructions for installing Trac on specific systems at [http://projects.edgewall.com/trac/wiki/TracInstallPlatforms TracInstallPlatforms] on the main Trac site, please be sure to first read through these general instructions to get a good understanding of the tasks involved.

== Requirements ==

To install Trac, the following software packages must be installed:

 * [http://www.python.org/ Python], version >= 2.3.
   * Python 2.4 is not supported on Windows since there are no Subversion bindings available for it.
   * Please keep in mind that for RPM-based systems you might also need the `python-devel` and `python-xml` packages.
 * [http://www.swig.org/ SWIG], version >= 1.3.21.
   * For versions of SWIG prior to 1.3.24, make sure to also build SWIG runtime support (`make runtime && make install-runtime`).
   * Also note that the bindings of Subversion <= 1.1.3 have problems with versions of SWIG >= 1.3.22. Use SWIG 1.3.21 in conjunction with Subversion <= 1.1.3.
 * [http://subversion.tigris.org/ Subversion], version >= 1.0. (>= 1.1 recommended)
 * [http://svnbook.red-bean.com/svnbook-1.1/ch08s02.html#svn-ch-8-sect-2.3 Subversion Python bindings]
   * Trac uses the [http://www.swig.org/ SWIG] bindings included in the Subversion distribution, '''not''' [http://pysvn.tigris.org/ PySVN] (which is sometimes confused with the standard SWIG bindings).
   * If Subversion was already installed without the SWIG bindings, you'll need to re-`configure` Subversion and `make swig-py`, `make install-swig-py`.
 * [http://www.clearsilver.net/ ClearSilver], version >= 0.9.3

=== For SQLite ===

 * [http://www.sqlite.org/ SQLite], version 2.8.x or 3.x
 * [http://pysqlite.org/ PySQLite]
   * version 1.0.x (for SQLite 2.8.x)
   * version 1.1.x or 2.x (for SQLite 3.x)
   Question: ''should that be: version 1.1.x or 1.2.x (for SQLite 3.x)? trac failed with pysqlite2.0.3 for me)''
=== For PostgreSQL ===

 * [http://www.postgresql.org/ PostgreSQL]
 * [http://initd.org/projects/psycopg1 psycopg1], [http://initd.org/projects/psycopg2 psycopg2], or [http://pypgsql.sourceforge.net/ pyPgSQL]

=== Optional Requirements ===

 * A CGI-capable web server, or
 * a [http://www.fastcgi.com/ FastCGI]-capable web server (see TracFastCgi), or
 * [http://httpd.apache.org/ Apache] with [http://www.modpython.org/ mod_python 3.1.3+] (see TracModPython)
 * [http://docutils.sourceforge.net/ docutils], version >= 0.3.3 for WikiRestructuredText.
 * [http://peak.telecommunity.com/DevCenter/setuptools setuptools], version >= 0.5a13 for using plugins

'''Attention''': The various available versions of these dependencies are not necessarily interchangable, so please pay attention to the version numbers above. If you are having trouble getting Trac to work please double-check all the dependencies before asking for help on the MailingList or IrcChannel.

== Installing the required software ==
As written above, there is some software needed to run trac. The following steps will guide you trough the most important mistakes.

=== Subversion ===
Most distributions are providing swig, so this is not a problem. After installing swig, download the latest subversion release. After ./configure make and make install, 
{{{
make install-swig-py
ln -s /usr/local/lib/svn-python/svn /usr/lib/python/site-packages/svn
ln -s /usr/local/lib/svn-python/libsvn /usr/lib/python/site-packages/libsvn
}}}

== clearsilver ==

{{{
./configure --with-python=/usr/bin/python 
}}}

make install unforunatly does not install neo_cgi.so to the python directoy, this has to be done manually:

{{{
cp python/neo_cgi.so /usr/lib/python/site-packages/
}}}

To be completed...

== Installing Trac ==

Like most Python programs, install the Trac Python package by running the following command at the top of the source directory:
{{{
$ python ./setup.py install
}}}

''Note: you'll need root permissions or equivalent for this step.''

This will byte-compile the python source code and install it in the `site-packages` directory
of your Python installation. The directories `cgi-bin`, `templates`, `htdocs` and `wiki-default` are all copied to `$prefix/share/trac/.`

The script will also install the [wiki:TracAdmin trac-admin] command-line tool, used to create and maintain [wiki:TracEnvironment project environments], as well as the [wiki:TracStandalone tracd] standalone server.

=== Advanced Users ===

To install Trac to a custom location, or find out about other advanced installation options, run:
{{{
$ python ./setup.py --help
}}}

Specifically, you might be interested in:
{{{
$ python ./setup.py install --prefix=/path/you/want
}}}


== Creating a Project Environment ==

A [wiki:TracEnvironment Trac environment] is the backend storage where Trac stores information like wiki pages, tickets, reports, settings, etc. An environment is basically a directory that contains a human-readable configuration file and various other files and directories.

A new environment is created using [wiki:TracAdmin trac-admin]:
{{{
$ trac-admin /path/to/projectenv initenv
}}}

[wiki:TracAdmin trac-admin] will prompt you for the information it needs to create the environment, such as the name of the project, the database connection string, and so on.

''Note: The user account under which the web server runs will require write permissions to the environment
directory and all the files inside.''


== Running the Standalone Server ==

After having created a Trac environment, you can easily try the web interface by running the standalone server [wiki:TracStandalone tracd]:
{{{
$ tracd --port 8000 /path/to/projectenv
}}}

Then, fire up a browser and visit `http://localhost:8000/`. You should get a simple listing of all environments that tracd knows about. Follow the link to the environment you just created, and you should see Trac in action.


== Running Trac on a Web Server ==

Trac provides three options for connecting to a “real” web server: [wiki:TracCgi CGI], [wiki:TracFastCgi FastCGI] and [wiki:TracModPython mod_python]. For decent performance, it is recommended that you use either FastCGI or mod_python.


== Using Trac ==

Once you have your Trac site up and running, you should be able to browse your subversion repository, create tickets, view the timeline, etc.

Keep in mind that anonymous (not logged in) users can by default access most but not all of the features. You will need to configure authentication and grant additional [wiki:TracPermissions permissions] to authenticated users to see the full set of features.

''Enjoy!''
