Make sure your operating system packages are up to date by executing the following command:
yum update -y
In order to have all the proper dependencies installed, execute the following command:
yum groupinstall "Development Tools"
Then, follow the steps described below:
cd /root/ wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p194.tar.gz tar xvzf ruby-1.9.3-p194.tar.gz cd ruby-1.9.3-p194 ./configure make make install
Once the install is complete, verify the version of Ruby:
ruby --version ruby 1.9.3p194 (2012-04-20 revision 35410)
Update to the latest RubyGems version (RubyGems is a sophisticated package management framework for Ruby.):
cd /root/ wget http://production.cf.rubygems.org/rubygems/rubygems-1.8.24.tgz tar xvzf rubygems-1.8.24.tgz cd rubygems-1.8.24 ruby setup.rb
Verify the version of RubyGems:
gem --version 1.8.24
Ensure you have the latest gem versions:
gem update --system
Install the Rake build language (Rake is a build tool written in Ruby, similar to make):
gem install rake
Install all of Rails and its dependencies:
gem install rails
List the installed gems:
That’s it! You now have a full Ruby on Rails stack up on CentOS 6.2.
