RVM: Ruby Version Management
Step 1: Install Required Packages
Firstly we need to install all required packages for ruby installation on our system using following command.
# yuminstall gcc-c++ patch readline readline-devel zlib zlib-devel # yuminstall libyaml-devel libffi-devel openssl-devel make # yuminstall bzip2 autoconf automake libtool bison iconv-devel
Step 2: Install RVM
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
Step 3: Setup RVM Environment
RVM provides a shell script to setup system environment before installing Ruby. Use below command to setup rvm environment.
# source/etc/profile.d/rvm.sh
Step 4: Install Ruby
After completing setup of RVM environment, lets install Ruby language using following command.
# rvm install2.1.2

Please read 'rvm help mount' to get more information on binary rubies. Checking requirements for centos. Requirements installation successful.

Install of ruby-2.1.2 - #complete Ruby was built without documentation, to build it run: rvm docs generate-ri
Step 5: Setup Default Ruby Version
Use rvm command to setup default ruby version to be used by applications.
#rvm use 2.1.2 --default Using /usr/local/rvm/gems/ruby-2.1.2
Step 6: Check Current Ruby Version.
Using following command you can check the current ruby version is used.
# ruby --version ruby 2.1.2p95 (2014-05-08 revision 45877) [i686-linux]
