Setup Ruby on Rails for CentOS or Fedora

This tutorial will guide you through setting up a basic Ruby on Rails environment, installing:

  • Ruby 1.8.7
  • RubyGems 1.8.15
  • Rails 3.1.3
  • Sqlite3
This tutorial was written for CentOS, Fedora, and other EL-based systems.
To start, log in to your VPS via SSH and update your system:
# yum update
Install Ruby:
# yum install ruby ruby-devel ruby-irb ruby-rdoc ruby-ri
Check the version installed:
# ruby -v
Install RubyGems:
# mkdir ~/sources
# cd ~/sources
# wget
# tar xzvf rubygems-1.3.1.tgz
# cd  rubygems-1.3.1
# ruby setup.rb
Update RubyGems:
# gem update –system
Install Rails:
# gem install rails
Install Sqlite3:
# yum install sqlite-devel
# gem install sqlite3-ruby
Install Postfix and Subversion:
# yum install postfix subversion -y
You should now have an updated and functional RoR environment!
