This covers installation and quick configuration of VNC on a server, in the event that Desktop access is needed on a remote server. In some cases, the CLI is not enough, and I've found this very useful.
On to the entry:
1. Login as root (or su)
2. Install required packages:
yum -y install vnc-server
3. Secure the VNC server:
the passwd folder should be listed
4. Configure the server:
add to end of file:
VNCSERVERARGS  = "-geometry 1024x768"
5. Start the VNC service and configure service to autostart on boot:
service vncserver start
chkconfig vncserver on
6. Further configuration:
add under the line "# Add the foll..."
(while true ; do xterm ; done) &remove comments(#) from
#unset SESSION_MANAGER7. Restart the vnc service
Service vncserver restart
8. Configure firewall to allow VNC server traffic
add 5903:tcp to exceptions list
9. Open VNC client from remote peer and connect to VNC Server:
password: mypassword (as set in Step 3)
