Quick reference on installing specific versions of rails on an “older” version of ubuntu without the need of having all packages in the ubuntu repositories.
\curl -L https://get.rvm.io | bash -s stable --ruby /usr/local/rvm/bin/gem install ... (all needed gems) /usr/local/rvm/bin/gem install passenger apt-get install libcurl4-openssl-dev apache2-threaded-dev /usr/local/rvm/gems/ruby-2.0.0-p247/gems/passenger-4.0.10/bin/passenger-install-apache2-module The Apache 2 module was successfully installed. Please edit your Apache configuration file, and add these lines: LoadModule passenger_module /usr/local/rvm/gems/ruby-2.0.0-p247/gems/passenger-4.0.10/buildout/apache2/mod_passenger.so PassengerRoot /usr/local/rvm/gems/ruby-2.0.0-p247/gems/passenger-4.0.10 PassengerDefaultRuby /usr/bin/ruby1.8 After you restart Apache, you are ready to deploy any number of Ruby on Rails applications on Apache, without any further Ruby on Rails-specific configuration!
After doing so, you can continue to install redmine as described in http://www.redmine.org/projects/redmine/wiki/RedmineInstall
/usr/local/rvm/gems/ruby-2.0.0-p247/bin/bundle install --without development test
This will fail if the environment is not set correctly – this helped me a lot:
And finally the last missing gem:
/usr/local/rvm/bin/gem install rake -v=10.1.0
