Ruby RVM, or Ruby Version Manager is a very convenient way of running multiple versions of ruby/jruby on the same machine without install/uninstall it every time. It also applies with using different ruby gem verionsets.
You should be aware, that ruby gems used with RVM are not transparent. It means that once you installed gem for ruby 1.9.3 and change the usage to ruby 1.6.3, you have to install all ruby gems for the given ruby version again.
Unfortunately, its installation is a little bit tricky as well as its usage.
I. Installing ruby
There are number of the ways of how ruby is installed, yum, from the the source, etc, so I skip this part. I personally, prefer an installation from the source
$> /usr/bin/env ruby -v
ruby 1.9.3p0 (2011-10-30 revision 33570) [i686-linux]
II. Installing GIT, that it is required for RVM installation:
It seems that there is no GIT available through base CentOS 5 repository, so I found a third-party repository, that seems works pretty good. They operate a term of “latest”, that on the time of writing the article is GIT 1.7.6.

III. Install RVM gem
$> sudo gem install rvm
/usr/local/lib/ruby/1.9.1/yaml.rb:56:in `
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
Fetching: rvm-1.9.2.gem (100%)
********************************************************************************
This gem contains only the Ruby libraries for the RVM Ruby API.
In order to install RVM please use one of the methods listed in the
documentation:
https://rvm.beginrescueend.com/rvm/install/
such as,
bash < <(curl -s -B https://rvm.beginrescueend.com/install/rvm) followed by placing the sourcing line in your ~/.bash_profile or wherever may be appropriate for your setup (example, .zshenv, /etc/profile, ...): # Load RVM into a shell session *as a function* [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" After completing setup please open a new shell to use RVM and be sure to run 'rvm notes' to gain a list of dependencies to install before installing the first Ruby. You can read more details about this process on the above mentioned install page as well as the basics page: https://rvm.beginrescueend.com/rvm/basics/ Enjoy! ~Wayne ******************************************************************************** Successfully installed rvm-1.9.2 1 gem installed Installing ri documentation for rvm-1.9.2...

IV. Perform RVM install

$> bash << rvm.bash
$> cat rvm.bash | bash

$USER,
If you have any questions, issues and/or ideas for improvement please
fork the project and issue a pull request.
If you wish to disable the project .rvmrc file functionality, set
rvm_project_rvmrc=0 in either /etc/rvmrc or ~/.rvmrc.
NOTE: To Multi-User installers, please do NOT forget to add your users to the 'rvm'.
The installer no longer auto-adds root or users to the rvm group. Admins must do this.
Also, please note that group memberships are ONLY evaluated at login time.
This means that users must log out then back in before group membership takes effect!
Thank you for using RVM!
I sincerely hope that RVM helps to make your life easier and more enjoyable!!!
~Wayne
SYSTEM NOTES:
If you do not wish to enable reading of per-project .rvmrc files, simply set:
export rvm_project_rvmrc=0
within either your /etc/rvmrc or $HOME/.rvmrc file, then log out and back in.
You _must_ read 'rvm requirements' for additional OS specific requirements for
various rubies, and native-extension gems. Expect failures until those are met!
You must now complete the install by loading RVM in new shells.
If you wish to use RVM in an interactive fashion in your shells then
Place the following line at the end of your shell's loading files
(.bashrc or .bash_profile for bash and .zshrc for zsh),
after all PATH/variable settings:
[[ -s "/home/$USER/.rvm/scripts/rvm" ]] && source "/home/$USER/.rvm/scripts/rvm" # This loads RVM into a shell session.
You only need to add this line the first time you install RVM.
If you are choosing to source RVM into your environment to switch current
shell environments, be sure to close this shell and open a new one so that
the RVM functions load.
Installation of RVM to /home/$USER/.rvm/ is complete.
Requirements for Linux ( CentOS release 5.7 (Final) )
NOTE: 'ruby' represents Matz's Ruby Interpreter (MRI) (1.8.X, 1.9.X)
This is the *original* / standard Ruby Language Interpreter
'ree' represents Ruby Enterprise Edition
'rbx' represents Rubinius
bash >= 4.1 required
curl is required
git is required (>= 1.7 recommended)
patch is required (for ree and some ruby-head's).
To install rbx and/or Ruby 1.9 head (MRI) (eg. 1.9.2-head),
then you must install and use rvm 1.8.7 first.
NOTE: To all Multi-User installers - DO NOT forget to add your users to the 'rvm' group.
The installer does not auto-add any users to the rvm group. Admins must do this.
Group memberships are ONLY evaluated at login time. Log them out, then back in.
Additional Dependencies:
# For Ruby / Ruby HEAD (MRI, Rubinius, & REE), install the following:
ruby: yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bison iconv-devel ## NOTE: For centos >= 5.4 iconv-devel is provided by glibc
# For JRuby, install the following:
jruby: yum install -y java

Upgrade Notes
* rvm_trust_rvmrcs has been changed to rvm_trust_rvmrcs_flag for consistency
* Project rvmrc files are now checked for trust whenever they change, as
promised by the note displayed during the review process
* Ruby package dependency list for your OS is given by:
rvm notes
* If you encounter any issues with a ruby 'X' your best bet is to:
rvm remove X ; rvm install X
* If you see the following error message: Unknown alias name: 'default'
re-set your default ruby, this is due to a change in how default works.
* after_use and after_cd hook now supports multiple files with after_*_*
the custom hooks can be easily turned on/off by:
chmod +x /home/$USER/.rvm/hooks/after_cd_[hook_name]
chmod -x /home/$USER/.rvm/hooks/after_use_[hook_name]
Upgrade of RVM in /home/$USER/.rvm/ is complete.
