RHEL

When I first got started with computers, there really was no choice for how you installed software. Indeed, you tended to do things like boot off a different cassette tape, pluggable cartridge or later, floppies. But then, there was a little bit of evolution, and you would boot the operating system off of one set of media, and insert a new floppy to run the program. There were no hard drives for these computers, those were reserved for the systems which colleges/universities and businesses had, and they cost in some cases, tens of thousands of dollars.

So, as a part of my working to retire an ancient (20 year old) server which I have been using as a NFS server, among other things, I had one major task before me... fix things so that my NAS server could be used for the what I intended. But I was having some issues around 8 years ago when I first tried this, and I don't remember all the issues, since work kept me from attacking this problem at the time.

I just posted a video which briefly goes into SELinux, how it relates to cobbler, and how to tell if an error is related to SELinux.

Well, earlier today, I got a reminder that I had not upgraded PHP. Indeed, unlike most of my installs, the virtual host running my WordPress sites was installed from a Live CD, and was running the dated PHP 5.4 version which CentOS/RHEL 7 comes with as a part of their base. It is a joy of running an operating system which comes with "long term support", aka LTS.
