First install RVM and set it up:
sudo yum install rubygem-rvm rvm-install
To include RVM into your bash shell, add following line to ~/.bashrc:
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This loads RVM into a shell session.
Now install JRuby and use it as default Ruby interpreter:
source ~/.bashrc rvm install jruby-1.5.6 rvm use jruby-1.5.6
Setup Rails environment:
gem install rails gem install bundler
Lets create a new Rails application:
rails new rails-app cd rails-app bundle install rails g scaffold Person name:string rake db:migrate rails s
Now go to http://localhost:3000/people/
Yay! Your new Rails application is up and running, powered by JRuby ( setup using RVM ).
