Most of the tutorials I've worked through ask for SELinux to be disabled.  Which obviously completely defeats the purpose.  But yes, SELinux can be a headache for a beginner.  If you have time for a tutorial one day, like the one for changing Port 22, it would be awesome.  

For now my easiest out has been to disable SELinux as part of setting up httpd.  

Meaning a total newbie tutorial?.. I'll review what you wrote on the subject and will see why you didn't get it to work with CentOS 7.

It should just work but I'm sure there is something in the configs that makes it fail.

More on this, next weekend!

Thanks @fChk.  I should close this discussion.  @Mashiroame to the rescue with an awesome tutorial using Debian 10 and installing LEMP + WP from the command line:

He also did a step by step (no steps missed) tutorial for installing phpmyadmin:

What was particularly awesome was that I was able to upgrade my Debian 8 Version to Debian 10 from the command line by another tutorial of his of 2019:

As I was working through the steps, I discovered all of the gaps in the tutorials I'd worked through previously when I was trying to install LAMP and then LEMP with WP earlier on.
