Install / Configure Xfce and VNC Server on CentOS7

xRDP protocol is a bit slow to connect based on my previous testing. This time, I am trying to use VNC protocol to do connection, which has been proven much faster than xRDP.

My previous post "Connect to GNOME desktop environment via xRDP on CentOS 7 & Ubuntu 18" shows how to use RDP client connecting to linux but connection speed is too slow for regular operation. Compared both, VNC solution is much better for daily operation remote control experience when using it on Linux server.
