How to install Trac 0.12 on ubuntu 11.10 machine with apache2 using wsgi. (everytime I use vim you can user any editor you want (nano, gedit..))

'''Install trac''' (and usefull plugins) from repository:

{{{
sudo apt-get install trac trac-accountmanager trac-graphviz trac-icalviewplugin trac-mastertickets trac-wysiwyg trac-wikitablemacro trac-tags trac-customfieldadmin trac-datefieldplugin
}}}

If you're going to use sqlite for db (as I do) install python-sqlite:

{{{
sudo apt-get install sqlite3 python-sqlite
}}}


'''install sendmail''' (if not installed already):

{{{
sudo apt-get install sendmail
}}}

'''add trac user:'''

{{{
sudo adduser --system --shell /bin/sh --gecos 'trac project managment' --group --disabled-password --home /var/trac trac
}}}

'''add www-data to trac group''' so apache can access trac files

{{{
sudo usermod -aG trac www-data
}}}


'''login as trac user''' start bash and swich to homedir:

{{{
sudo su trac
bash
cd
}}}

'''make directory for all projects and create new project'''

{{{
mkdir projects
cd projects
trac-admin android initenv
trac-admin android deploy android/deploy
}}}
and finish instalation

'''change permissions so group can write/read/execute'''

{{{
chmod 0775 . -R
}}}

You can add as many projects as you want. And even later, all you have to do create new project, deploy it and you're set.

'''back to your user'''. 
pressing CTRL+d twice should get you back.

now we'll configure apache

Open apache apache site file what you want to use for trac (default should be fine). In my case I have Virtualhost for subdomain trac.

{{{
vim /etc/apache2/sites-enabled/trac
}}}
and looks like:

{{{
<VirtualHost *>
  ServerName trac.domain.my
  DocumentRoot /var/trac/projects

  WSGIScriptAlias ^/([^/]+) /var/trac/projects/$1/deploy/cgi-bin/trac.wsgi
  <Directory /var/trac/projects>
    WSGIApplicationGroup %{GLOBAL}
    Options Indexes +ExecCGI +SymLinksIfOwnerMatch
    AllowOverride None
    Order allow,deny
    allow from all
  </Directory>

  <LocationMatch /[^/]+/login>
   AuthType Basic
   AuthName "trac"
   AuthUserFile /var/trac/.passwd
   Require valid-user
  </LocationMatch>

... trac unrelated stuff...

</VirtualHost>
}}}

WSGIScriptAlias does all the magic. it gets project name from url and redirects to trac.wsgi in that project.
If you're not running trac sites as subdomain but as folder in your documentroot (i.e. domain.ur/trac/myproject) replace 
{{{
^/([^/]+)
}}}
line with 
{{{
^/trac/([^/]+)
}}}
(there's just added 'trac/'). And make sure that /var/trac/projects is in DocumentRoot.

'''reload apache configuration'''

{{{
sudo service apache2 reload
}}}

You should be done
