Ruby is an object-oriented programming language that is similar in syntax to Perl and Python. The version of Ruby that ships with CentOS 6.2 is 1.8.7. If you need the latest version, you can download, compile and install Ruby from source code. This is a quick tutorial on installing Ruby 1.9.3 and Rubygems 1.8.24 on CentOS 6.2 from source.
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:
gem list
That’s it! You now have a full Ruby on Rails stack up on CentOS 6.2.

Please install yaml first
$ wget http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz
$ tar xzvf yaml-0.1.4.tar.gz
$ cd yaml-0.1.4
$ ./configure –prefix=/usr/local
$ make
$ sudo make install
Lenny
libyaml-0.1.4-1.el6.rf.x86_64 is available in the rpmforge repo so there’s no need to build it.

Thanks. Really helpful article.

Need to also make sure readline-devel is installed before compile.
Great post!

Thank you very much for the detailed steps (including the description of each step). It saved a lot of my time

Thanks for this tutorial. I used it to install Ruby-1.9.3 on CentOS 6.5 .
I had to apply the patch at https://gist.github.com/spkane/8059362 to fix openssl compile errors that I encountered after uninstalling CentOS 6.5’s included version of Ruby.
This line seemed to cover any dependencies I needed:
yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libffi libyaml libyaml-devel libffi-devel openssl-devel

Followed the ruby install but it did not update my current version. Do I just copy the contents from the ruby-1.9.3.-p194 folder to /usr/bin

Great stuff.
But needs to be updated since rubyforge shut down May 2014 and has now been replaced by rubygems.org.
So, currently as of this writing these are the modifications to the above I used
Ruby
wget http://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p481.tar.gz
Ruby Gems
wget http://production.cf.rubygems.org/rubygems/rubygems-2.3.0.tgz
Also, CentOS 6.5 wants to see gem in /usr/bin/ while the current installer installs into /usr/local/bin/ so I created a symlink
ln -s /usr/local/bin/gem /usr/bin/gem

Thanks for pointing out. The post has been updated.
