To install ruby and rubygems on centOS, Run on Terminal

sudo yum install ruby
sudo yum install rubygems

To check version of of ruby and rubygems, Run

ruby -v
gem -v

Note: gem --version is same as gem -v

Update the gems list using : 

sudo gem update
sudo gem update --system

Now, you can install any gem, using command

gem install <gem_name>

For instance, To install rails on centOS, Run

sudo gem install rails
