Posted onInstall Ruby 1.9.3 ( or Multiple Ruby Version ) on CentOS, RedHat using RVM
I am using CentOS 6.3, below is easy steps to install ruby using RVM , or Ruby Version Manager. RVM provides easy set of commands to install single or multiple versions of Ruby on single server.
Step 1: Upgrade Packages
It is the best practice to keep your system up to date with latest packages. Before running below command make sure that update will not affect to your running apps ( if any )on server else skip it /# yumupdate
Step 2: Installing Recommended Packages
There are few developemnt libraries required to run Ruby on Linux. Use following command to install recommended packages on your server using yum. /# yuminstallgcc-c++ patch readline readline-devel zlib zlib-devel /# yuminstalllibyaml-devel libffi-devel openssl-devel make /# yuminstallbzip2 autoconf automake libtool bison iconv-devel
Step 3: Install RVM ( Ruby Version Manager )
Install latest stable version of RVM on your system using following command. This command will automatically download all required files and install on your system. /# curl -Lget.rvm.io| bash -sstable
[Sample Output]
[root@redhat6 beef]/# rvm install 1.9.3
bash: rvm: command not found
[root@redhat6 beef]/# curl -L get.rvm.io | bash -s stable

Creating group 'rvm'
Installing RVM to /usr/local/rvm/
Installation of RVM in /usr/local/rvm/ is almost complete:
/* First you need to add all users that will be using rvm to 'rvm' group,
and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.
/* To start using RVM you need to run source /etc/profile.d/rvm.sh
in all your open shell windows, in rare cases you need to reopen all shell windows.
