'''Note:''' It is always best practice to use the latest [wiki:WikiStart stable version] of Trac.

'''DB:''' Most tutorials do not say the database they are using. I assume the default is SQLite.

'''Ubuntu 8.04.2 Hardy Note:''' the default package installs trac-post-commit-hook under /usr/share/doc/trac/contrib path. Unfortunately this script is not working correctly with Trac 0.11 and you need to download the latest version from [source:0.11-stable/contrib/trac-post-commit-hook].

== Installing Trac on Ubuntu ==
This is a short recipe to install and configure a virtual `Apache2` host with `Trac`

=== Which Ubuntu packages are needed ===
The typical procedure to install Trac under Ubuntu with its default dependencies (default - chosen by apt) is:
{{{#!sh
apt-get install python python-babel
apt-get install trac
}}}
Ensure that the python version matches the Trac latest, otherwise apt will install an older Trac version which matches the older version of python that you have installed. Also take into account that `python-babel` should be always installed before `trac` if you wish to later configure internationalisation.

==== Upgrade python packages ====
Ubuntu pre-packaged python resources are not always the newest; you may consider to upgrade them with `easy_install` or `pip`
- Upgrade with `easy_install`
{{{#!sh
easy_install Babel
easy_install Trac
}}}
- Upgrade with `pip` (another python installer, namely `python-pip`)
{{{#!sh
apt-get install python-pip
pip install --upgrade Babel
pip install --upgrade Trac
}}}

=== Configuring a virtual host ===
Here is a sample virtual host configuration running under `apache2` (one file) with minimal, "entry level" settings. 
The config file should be created at the `apache2` known place for site configs (see below), and then the configured site can be "enabled" to run.

The following considerations used within this config, yours may vary, so adjust them below appropriately at your own 
- `trac.local` is a hostname of virtual host
- `/var/local/trac` is a directory (Trac project) at that host
- `/var/local/trac/.htpasswd` is a password file created with `htpasswd` utility
- `ru_RU.UTF8` is a locale ident
==== Prepare configuration
First you need to 
- create directory for Trac project and change its access permissions to that under which `apache2` runs (`www-data` in most cases)
- initialize `Trac` environment within that directory
- create `apache2` htpasswd entry for authorized web user access within this directory
- add to Trac this authorized web user with administrative privileges over Trac
{{{#!sh
mkdir -p /var/local/trac
trac-admin /var/local/trac initenv
htpasswd -c /var/local/trac/.htpasswd adminusername
trac-admin /var/local/trac permission add adminusername TRAC_ADMIN
chown -R www-data: /var/local/trac
chmod -R 775 /var/local/trac 
}}}
Create config file with any text editor (`vi` in this example):
{{{#!sh
vi /etc/apache2/sites-available/trac.conf
}}}
Enter the following copy-paste into this file:
{{{#!text/html
<VirtualHost *:80>
        ServerName trac.local
        <Location />
           SetHandler mod_python
           PythonInterpreter main_interpreter
           PythonHandler trac.web.modpython_frontend
           PythonOption TracEnv /var/local/trac
           PythonOption TracEnvParentDir /var/local/trac
           PythonOption TracUriRoot /
           PythonOption TracEnv /var/local/trac
            # PythonOption TracEnvIndexTemplate /var/local/trac/templates/index-template.html
           PythonOption TracLocale en_US.UTF8
           PythonOption PYTHON_EGG_CACHE /tmp
           Order allow,deny
           Allow from all
        </Location>
        <Location /login>
          AuthType Basic
          AuthName "myproject"
          AuthUserFile /var/local/trac/.htpasswd
          Require valid-user
        </Location>
</VirtualHost>
}}}
==== Enable prepared configuration
{{{#!sh
sudo apt-get install libapache2-mod-python
a2enmod python
a2ensite trac.conf
service apache2 restart
}}}
