Thank you for your answer.
I allready tried this instructions, but did not get it to work. Now I found out, that I made a mistake. Corrected it, but got severall errors.
I think my tries corrupted something on my system. I am just installing a fresh server and then try again.
This time I will make a backup of the VMware Image, before doing any further installation. Just to be sure to get back to a fresh system within minutes.
