How to Install and Configure Cobbler on CentOS 7

The original installation instructions I found are here, and unfortunately they didn’t quite work. I’m starting to notice a trend. Either my Google-Foo is getting worse, or people are getting lazy with directions. The Cobbler Quickstart Guide is the best and most up-to-date I have found. Early in my career I worked with an Engineer who was a wizard with all things Linux. He helped me with kickstarting boxes, and I never found the time, or I guess, wanted to find the time to learn the system. It turns out it was easier than I thought. Now if only I could master regular expression like he could.
