Working with yum module on CentOS

Using `yum module` allows much greater flexibility in determining what software can be installed on your servers. It allows you to leave security and bug fix patches up to the CentOS team instead of having to manually compile or build your own RPMs, even for packages that may be out of date. In this lab, we'll work on understanding how modules can be used.
