RVM¶
RVM is a software dedicated to managing multiple Ruby interpreter installations. There are several advantages of using RVM, most notably the ability to set up your own gems and update them to your chosen version.
RVM installation¶
Once installed RVM can be used later for all custom domains.

Ruby was built without documentation, to build it run: rvm docs generate-ri
$ gem install bundler
(...)
1 gem installed
Variables¶
Setting a variable from the SSH with visibility for the application launched by Passenger is possible by adding variables to the ~/.bash_profile file (e.g. export TESTENV = 1).
Warning
Variables will not be used from ~/.bashrc or ~/.shrc
Rebuild¶
Ruby:
rvm reinstall ruby-X.X.X --autolibs=disabled
X.X.X is the version of Ruby in use in RVM.
Gems:
gem pristine --all
