Someone had mentioned on this list the following RedHat Enterprise 7 (and as you know CentOS is binary replica of RedHat Enterprise with replaced art work):

so if I buy RHEL 7 books everything should work as in the book? part of the problem for me is that there aren't many books about CentOS, and the ones I found are a few years old
This covers CentOS 7 system administration sufficiently well for me (but I work with Linux and Unix for over 1.5 decades...).
So, if you decided to walk away from Windows, after you master Linux (or maybe simultaneously with starting it), take a look at Unix successors such as FreeBSD (most suitable for servers IMHO, some may recommend OpenBSD for servers, my preference is FreeBSD), NetBSD (most rich with what is ported to build and run on it), PC-BSD - based on FreeBSD, yet made easiest to install workstation whith GUI interface (X11) support.
I understand, but this is primarily for servers for emails, web, etc., and it is my understanding that CentOS is one of the better distributions for that kind of stuff.
I would say, CentOS 6 is the best of Linuxes suitable for server (IMHO). However, I for one decided to move my servers away from Linux (as from "Unix-like" Linux gradually becomes "Windows-like" during last 5 years or so). Since some time ago I do not upgrade Linux systems on servers I maintain. Instead, when the time comes, I just migrate server from Linux to FreeBSD, which is much more suitable platform for server than Linux. Version 7 of RedHat Enterprise or CentOS is much worse than version 6 to build server on. Again, this is just my humble opinion. If I absolutely have to build server on today's latest Linux, I will choose Debian, which at least doesn't have systemd yet. But it will have it in next release...
What changes have you seen that affect using CentOS as a server? Sure, the GUI has changed over the years to be more like Windows, but most of my servers don't even have a GUI installed. I have servers running CentOS 4, 5, 6, and 7. The only differences I can think of between 4 and 7 that affect server administration are selinux and systemd. Selinux can be easily disabled if you don't want to deal with it. I don't like systemd at the moment, but that's at least partially due to only having worked with it for a couple of weeks so far. The more I use it, the more I get used to it. So far, it seems easy enough to use once you figure out the new commands and file locations.
