Creating a local Yum Repository

When it comes to package management on Red Hat based systems Yum (Yellowdog Updater, Modified) is my preferred method. It's a quick and easy way of installing desired rpm's and their dependencies as Yum will automatically resolve dependencies before installation. Most Red Hat base distributions include a public facing Yum repository that you can configure yum to use in order to save from having to maintain a local copy of every package on each system.
