RVM works best with latest version of Phusion Passenger. Latest Phusion Passenger has full integration support for RVM and should work out of the box with no configuration. The only thing you need to tell Phusion Passenger is which Ruby you want to use for which app.

RVM also works with Phusion Passenger 3.x, although later versions have much better RVM support. Instructions for 3.x can be found here.

∞FAQ

• Q: Can I run multiple projects under Phusion Passenger with each project on a different Ruby version?

  A: Yes, since Phusion Passenger 4.

• Q: How do I use custom gemsets under Phusion Passenger?

  A: Switch to that gemset first, then run 'passenger-config --ruby-command' as documented in the Phusion Passenger manual. It'll tell you what 'PasengerRuby'/'passenger_ruby' config option you should put in your virtual host. Edit your virtual host accordingly and restart the web server.

  A: Mainly the key to this is to use wildcards in the sudoers file as the following examples show: /usr/bin/env GEM_PATH=* GEM_HOME=* PATH=* passenger-status
