After Trac needs too much Requirements i look for another tool. I found Redmine.

Redmine is a flexible project management web application. Written using Ruby on Rails framework, it is cross-platform and cross-database.

Redmine is open source and released under the terms of the GNU General Public License v2 (GPL).

So Ruby is installed on my Server. Good.
The install runs without mistakes. Fine.

But the app did not run. I read the good documentation and found some about WEBrick.

ruby script/server webrick -e production

WEbrick is running but the app runs slow. After this test i started the mongrel server with:

mongrel_rails start -e production -p 3000 -d

Mongrel was not very stable. So i  changed to Passenger.

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-2.2.11/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-2.2.11
PassengerRuby /usr/bin/ruby1.8

Now on spooXe the Redmine Project Management Tool is running.
