Summary

You are now ready to walk out into the world and declare your new-found knowledge of CentOS. I have been able to help you through some simple best practice goals to manage the services we looked at throughout this book as well as introduce some new elements of CentOS 7. Of course, for a long time, you will still come across plenty of CentOS 6 systems to keep you busy, and most elements are consistent from Version 6 to Version 7, but keeping up to date with the latest enhancements is always useful.
