linux 7 minimal vnc
I have a server centos 7 minimal install. I believe low footprint of OS make it healthy and lightweight.
Now I want to configure vnc server on it. I want vnc command shell only Gui is not required. I mean I do not want to install Desktop...
How can I install-configure minimal vnc server please.

I don't understand the point of running a VNC server on a console-only system. Why not just ssh in? If you need to maintain a session through dis/reconnects then use screen.

yes ssh is used for operations. But we need a permanent session for running long operations like over night 8 hours...
We cannot take risk ssh may be disconnect for some reason after 5 hours.....

As I said in my previous post, if you need to maintain a session through dis/reconnects then use screen.
Code:
$ screen -S <session name>
Run whatever you want to run in the session, disconnect from it with Ctrl-A D, list all screen sessions with "screen -ls", reconnect to one with "screen -r <session name>", reconnect to one that's already connected to (forcing the other one off) with "screen -rD <session name>". If your ssh session dies for whatever reason, just ssh back in and reconnect to the screen session with "screen -r <session name>".

screen means Desktop Or something else...
if it means Desktop
then minimal OS installation will be replaces with GUI.

Ok Screen is absolutely which fullfill our requirements...
Thanks a lot.
But for my understanding can we configure vnc to run only console without desktop on minimal installation.

It's been awhile, but I seem to recall that running a job in background would make it immune to ssh disconnects. It would just keep running because, being in background, it was not connected to a terminal. Am I remembering correctly?
