Server CentOS 7: Installing GUI problem.

Hello. I ordered a VPN 12 gb ram, 6 cores etc. For testing and education porposes.

First i take only a SSH console connection nothing more.

I install first VNC Server via command line. and all worked fine! ( connection open ports ok )
After i install
" yum groupinstall "Server with GUI" "
I installed all ok great!

After i try to connect from Windows 10 with tightVNC and all work great!

BUT after i reboot the VPN and thats it. no connections. No ssh console nothing! I cant make nothing.

I made a restore.

After i install first VNC server and reboot. All ok
After that i install GUI and reboot and again and again nothing i cant access SSH.

After that i restore again.

How can i disable boot in GUI.? Any ideas?

Run the following command:

systemctl get-default
the return means the following:

Code: analogous to runlevel 3 analogous to runlevel 5
You want if that is not the case then run this command to set it;

systemctl set-default

i have found that the rhel7 gui installer may not set your network card online by default, make sure to go into the network settings on the installer and insure it's set be be on/connected after boot -- just look around, i don't recall the exact setting. ...and yes, that's just stupid for it to be like that.
