if you meant how to tell rails which environment to load when you start the server from command line, here's how:

rails server -e production


In general, Rails gets its environment from the RAILS_ENV shell variable at start-up, or defaults to "development". You can specify an environment for a rails command such as rails server, rails console (Rails 3), script/server or script/console (Rails 2.x) from the bash command line as follows...

RAILS_ENV=something rails s

This means to set the RAILS_ENV environment variable to "something" for the execution of the rails s command.
