On my development machine:
$ bundle exec rails console Loading development environment (Rails 3.2.3) 1.9.3p194 :001 > Rails.env => \"development\"
The rails executable can't know which environment should run on which machine.
you can put export RAILS_ENV=production in your ~/.bashrc or ~/.bash_profile file of the user you want to start the console with.
export RAILS_ENV=production
~/.bashrc
~/.bash_profile
