Trac on Fedora Core

Installing Trac On Fedora Core 4 (and higher) is easy with Yum and involves only 3 steps:

1) Verify you have configured Yum to use the Extras repository (which is enabled by default in Fedora Core 4 and higher) and run the following command in a terminal window:

  $ sudo yum install trac

Yum will take care of all dependencies on which the Trac package depends (including the python-clearsilver package) and will fetch and install them for you automatically.

2) Create a new project environment. An environment is basically a directory that contains a human-readable configuration file and various other files and directories.

Create a subversion repository if you don't already have one, for example in /srv/svn:

 $ sudo mkdir -p /srv/svn
 $ sudo svnadmin create  --fs-type fsfs /srv/svn

Next you need to decide where to store your trac project and create the directory, for example in the new directory /srv/trac:

 $ sudo mkdir -p  /srv/trac

Then create a new environment using trac-admin, as in this example for project foobar

 $ sudo trac-admin /srv/trac/foobar initenv

Now make it owned by apache:

 $ sudo chown -R apache /srv/trac
 $ sudo chown -R apache /srv/svn

3) Next, you need to edit the file /etc/httpd/conf.d/trac.conf to point to your new project environment, as in this example (using mod_python):

# The Location is the part after the host (http://example.com<Location>) that
# you want to serve the Trac site
<Location /trac>
   SetHandler mod_python
   PythonHandler trac.web.modpython_frontend
   # This is the folder you gave to trac-admin initenv earlier
   PythonOption TracEnv /srv/trac/foobar
   # This is the same as the Location above
   PythonOption TracUriRoot /trac
   # This should be some writable temporary directory
   SetEnv PYTHON_EGG_CACHE /tmp 
   # This can be any string, but must be the same for all
   # Trac instances on the same Apache install
   PythonInterpreter trac
</Location>
<Location /trac/login>
   AuthType Basic
   AuthName "alexandria"
   AuthUserFile /srv/trac/conf/trac.htpasswd
   Require valid-user
</Location>

The example above assumes you have a trac project environment setup in /srv/trac/foobar/ directory, described in step 2 and an htpasswd file at /opt/trac/trac.htpasswd for authentication purposes (see also wiki:TracModPython (too generic)).

You will need to tell Apache to reload configuration after editing trac.conf:

  $ sudo service httpd reload

Verify your Trac installation by pointing your browser at the correct URL for your Trac server (e.g. ​http://localhost/trac).

Notes on the Fedora Extras Trac package:

• trac.cgi and trac.fcgi are installed in /var/www/cgi-bin/ (actually, /usr/share/trac/cgi-bin for FC5).
• apache webserver config file is installed in /etc/httpd/conf.d/trac.conf

If you happen to come across any packaging issues, feature requests or problems on Fedora, you can submit a bugzilla bug for the Trac package at ​https://bugzilla.redhat.com/bugzilla/easy_enter_bug.cgi.

Be sure to check out the generic installation instructions in the TracGuide

SELinux

Fedora Core 5 ships with SELinux enabled by default. You need to make the Trac and Subversion directory accessible to the webserver. See ​http://fedora.redhat.com/docs/selinux-apache-fc3/ for details.

 $ sudo chcon -R -t httpd_sys_content_t /srv/trac
 $ sudo chcon -R -t httpd_sys_content_t /srv/svn

If you put these under /srv/www/trac and /srv/www/svn instead, the restorecon command will know that these attributes should be preserved. Alternatively, you can teach restorecon about these two directories by adding the lines:

 /srv/trac(/.*)?    system_u:object_r:httpd_sys_content_t
 /srv/svn(/.*)?     system_u:object_r:httpd_sys_content_t

to the file /etc/selinux/targeted/contexts/files/filecontexts.local. You may need to create this file if it is not already present.
