I use a Fedora 20 VM image to teach Oracle and MySQL technology. Last week, I expanded the Fedora VM image to support a full LAMP stack. This blog shows you how to install Ruby on Fedora and successfully generate the Rails gems.

Connect as the root user and use yum to install the libraries. My approach is by library or small groups. Naturally, you start with the ruby library.

yum install ruby

You will see the following:
