Centos system install vnc

Install RealVNC on CentOS7

Step 1: Check gnome version rpm -qa | grep -i gnome

gnome version is 3.14

So we run "yum update" to update gnome 3 from 3.14 to 3.22. Because there is a bug in gnome 3.14, that will cause vncserver-virtual :x failed.

yum update

Install Real VNC Server 6.0.1

rpm -ivh VNC-Server-6.0.1-Linux-x64.rpm
