Make vnc password for user (Ex. pirat9). Login to the user and run the following command:

$ vncpasswd

Configure VNC configuration for new user

Edit /etc/sysconfig/vncservers file and add the user name:


you can add more users with multiple different display size for every user.

VNCSERVERS="2:userx 3:usery 4:userz"
VNCSERVERARGS[2]="-geometry 1280x1024"
VNCSERVERARGS[3]="-geometry 1280x1024"
VNCSERVERARGS[4]="-geometry 800x600"

Make it to start automatically on every reboot and start the vnc service.

# chkconfig vncserver on

# /etc/init.d/vncserver start
