how to load passenger from apache with rvm and unique gem sets

I have two websites running on the same serve开发者_如何转开发r. Both use passenger and rvm. Each website has a unique rvm gemset. The problem I'm running into is how I would configure passenger to start up in apache.

Here's my apache passenger configurations:

ubuntu@www01:/etc/apache2/mods-enabled$ ls passenger.*
passenger.conf  passenger.load

ubuntu@www01:/etc/apache2/mods-enabled$ cat passenger.conf 
PassengerRoot /home/ubuntu/.rvm/gems/ruby-1.8.7-p334@snowcrash/gems/passenger-3.0.2
PassengerRuby /home/ubuntu/.rvm/wrappers/ruby-1.8.7-p334@snowcrash/ruby

ubuntu@www01:/etc/apache2/mods-enabled$ cat passenger.load 
LoadModule passenger_module /home/ubuntu/.rvm/gems/ruby-1.8.7-p334@snowcrash/gems/passenger-3.0.2/ext/apache2/mod_passenger.so

You can see from above, that I've configured apache to load the passenger module/configurations from the ruby-1.8.7-p334@snowcrash rvm gem set. My problem lies in having an additional gem set for my other website, ruby-1.8.7-p334@pixel-pets. I've thought about installed passenger in the global gem set, but I think it would see issues when it tries loading gems unique to my project specific gem sets.

Here are my installed gems for each project:

ubuntu@www01:/etc/apache2/mods-enabled$ rvm use 1.8.7@snowcrash
Using /home/ubuntu/.rvm/gems/ruby-1.8.7-p334 with gemset snowcrash
ubuntu@www01:/etc/apache2/mods-enabled$ gem list -l

In your .rvmrc do:

if [[ -s "/Users/sutto/.rvm/environments/ree-1.8.7-2010.02@my-app-name" ]] ; then
  . "/Users/sutto/.rvm/environments/ree-1.8.7-2010.02@my-app-name"
else
  rvm --create use  "ree-1.8.7-2010.02@my-app-name"
fi

Or just create it with:

cd path/to/project && rvm use ree-1.8.7-2010.02@my-app-name --rvmrc --create

Then in each rails project, add a new file config/setup_load_paths.rb and add

if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')
  begin
    rvm_path     = File.dirname(File.dirname(ENV['MY_RUBY_HOME']))
    rvm_lib_path = File.join(rvm_path, 'lib')
    $LOAD_PATH.unshift rvm_lib_path
    require 'rvm'
    RVM.use_from_path! File.dirname(File.dirname(__FILE__))
  rescue LoadError
    # RVM is unavailable at this point.
    raise "RVM ruby lib is currently unavailable."
  end
end

# Select the correct item for which you use below.
# If you're not using bundler, remove it completely.
#
# # If we're using a Bundler 1.0 beta
# ENV['BUNDLE_GEMFILE'] = File.expand_path('../Gemfile', File.dirname(__FILE__))
# require 'bundler/setup'
#
# # Or Bundler 0.9...
# if File.exist?(".bundle/environment.rb")
#   require '.bundle/environment'
# else
#   require 'rubygems'
#   require 'bundler'
#   Bundler.setup
# end

Of course you should replace /Users/sutto/.rvm by your rvm path, and ruby-1.8.7-p334@snowcrash by the correct gemset.
