Puppet
Puppet is a configuration management tool that is extreamly useful. It ensures that the admin just needs to manage a single resource instead of all the nodes in the cluster. It ensures that software is consistantly installed, configured, and properly started on all systems.
The puppet version in almost every repo is way to outdated. Puppet 2.7 or better is /higly/ recommended by this guide. Thankfully Puppet Labs provides a really good resource.
Check the Puppet Labs yum repo for the latest version. Look for the 'puppetlabs-release' rpm for the highest release.
$ sudo yum install https://yum.puppetlabs.com/el/6/products/x86_64/puppetlabs-release-6-6.noarch.rpm
Once that is installed, we can now install puppet.
$ sudo yum install puppet
Add "cname=puppet,frontend01" to /etc/dnsmasq.conf for cname record.
