Freezing isn't the best way, there's a much simpler method. 1) Define the version of Rails your app requires in config/ environment.rb. For example, one of the apps I've worked on this week has RAILS_GEM_VERSION = '2.1.2' unless defined? RAILS_GEM_VERSION
2) For each app you're running on the server, install that version's gem to the system like normal. For the above app, I'd do a sudo gem install rails --version='2.1.2' The app then selects the correct gem when it is started. You can have as many different versions of Rails installed to the system gem path as you like: [EMAIL PROTECTED] ~ $ ls -1d $GEMS/rails* /opt/local/lib/ruby/gems/1.8/gems/rails-1.2.5 /opt/local/lib/ruby/gems/1.8/gems/rails-2.0.2 /opt/local/lib/ruby/gems/1.8/gems/rails-2.1.0 /opt/local/lib/ruby/gems/1.8/gems/rails-2.1.1 /opt/local/lib/ruby/gems/1.8/gems/rails-2.1.2 /opt/local/lib/ruby/gems/1.8/gems/rails-2.2.0 [EMAIL PROTECTED] ~ $ I'm not sure whether rake gems:install handles this step; if it does, then things are even simpler. 3) Done.
