VNC server on CentOS7

https://www.tecmint.com/install-and-configure-vnc-server-in-centos-7/

Actual experience:

$ sudo yum install tigervnc-server
$ su - your_user  # If you want to configure VNC server to run under this user directly from CLI without switching users from GUI
$ vncpasswd
$ cp /lib/systemd/system/vncserver@.service  /etc/systemd/system/vncserver@:1.service
### then in the tutorial, a large number of lines need to be input, but since there already similar lines in the copied files, Only user name need to be replaced

$ systemctl daemon-reload
$ systemctl start vncserver@:1
$ systemctl status vncserver@:1
$ systemctl enable vncserver@:1

### for different user, create different tag, @:1, @:2, ...

$ ss -tulpn| grep vnc

$ firewall-cmd --add-port=5901/tcp
$ firewall-cmd --add-port=5901/tcp --permanent

### In the new Opera case, 5901 - 5920 has been permanently added in the firewall configuration.
