[CentOS] Centos7 Cant start vncserver

[anax]

Hi Robert
apparently vncserver writes its PID file somewhere else than into 
/home/root/.vnc/homebase.home.htt:3.pid, where systemd expects it to be.
Go into /lib/systemd/system/vncserver.service and correct the PID file 
location there, so that it matches the location where vncserver writes 
its PID file.
And then do a
systemctl deamon-reload
systemctl start vncserver

and then after the SECOND start of vncserver (not the first) it will work.
