Wish I would have kept up with all the commands, but did not...
I got CentOS Linux 8 - PowerTools installed. Then I have to enable it.
It is disabled by default:
dnf repolist all
sudo dnf config-manager --set-enabled powertools
Again to make sure enabled: dnf repolist all
Install lua if not already on system.
Then Apache will install on CentOS 8.
