I believe that there are two problems here.

Most recent Centos has changed to 'systemd' or some such
change that affects how system components are activated.

Centos also has name change on parts of mysql database to
'mariadb' and that needs a different activation syntax.

I suspect that your centosAutoInstallation.py script should be
updated to allow simple use with current Centos release.

I'll probably figure out a work-around but it would be helpfull to
other users also.
