I encountered a problem where I needed to have multiple versions of Ruby on the same instance of Phusion Passenger. I found a forum online that mentioned that starting with Passenger 4 multiple PassengerRuby definitions in the virtual host configuration can be used. The problem being Debian Wheezy currently uses Passenger 3. Upgrading Passenger is not difficult.

  • First install the Passenger gem:
    sudo gem install passenger
  • Then run the installer script:
    sudo passenger-install-apache2-module
  • Then update the Apache module configurations:
    sudo vi /etc/apache2/modules-available/passenger.conf

    And replace the contents with:

PassengerRoot /var/lib/gems/1.9.1/gems/passenger-4.0.29
PassengerDefaultRuby /usr/bin/ruby1.9.1

And also:

sudo vi /etc/apache2/modules-available/passenger.load

And replace the contents with:

LoadModule passenger_module /var/lib/gems/1.9.1/gems/passenger-4.0.29/buildout/apache2/


I got an error after restarting apache:

sudo service apache2 restart

Syntax error on line 8 of /etc/apache2/sites-enabled/puppetmaster:
Invalid command 'RackAutoDetect', perhaps misspelled or defined by a module not included in the server configuration
Action 'configtest' failed.

To fix this, I had to edit the /etc/apache2/sites-enabled/puppetmaster and remove the following lines:

RackAutoDetect Off
RailsAutoDetect Off

I also encountered a problem with getting the correct version of Ruby to run for the puppet master server. The problem was that I had the PassengerRuby directive set globally in the virtual host configuration, this is a problem because PassengerDefaultRuby is set to a different version of ruby. The fix was simple, by removing the PassengerRuby directive from the global virtual host and replacing it inside of the virtual directory configuration.
