kelunik and Kromey, thx for help. I am now one step further.
I reinstalled centos 7 and started from scratch.
(Yes with the reinstall, I deleted the /etc/letsencrypt/accounts folder)
I stoped apache (service httpd stop)
I ran the command
Congratulations! Your certificate and chain have been saved at
/etc/letsencrypt/live/myserver.de/fullchain.pem. Your cert will
on 2016-02-12. To obtain a new version of the certificate in
future, simply run Let’s Encrypt again.”
After starting the apache (service httpd start).
There is still no https available, just http.
localhost from the machine. I get the following results

I guess it
doesn’t work with centos 7 with a single command.
If yes, I am happy for any link/useful information
