configuration: is not valid domain name!

[joximu]

To the first thing about names:

we had it *really often* here that people give a domain name to their servers... instead of a hostname which - together with the domain - makes the FQDN (or FQHN)...

Maybe it's because people name their friends "Smith" even if his name is "John Smith"... I don't know....

Servername (FQDN/FQHN) = Hostname + Domain + TLD....


And to the MySQL problem: try connecting to mysql with the given credentials....
