To install VNC, we need to install the graphical environment (such as Gnome).
Install the required programs and modules:
#yum-y install firefox nano tigervnc-server tigervnc-server-module tigervnc-server-applet gtk-vnc python-gtk-vnc
Turn on AutoPlay:
shkconfig vncserver on
Add the user under which we will access the remote desktop
Assign a password for user
Now you need to go to Terminal 2 (or use the SU command) use user login and enter the following command
Set a password for VNC.
By Ruth Perezahodim.
Change the configuration file/etc/sysconfig/vncservers
VNCSERVERS = “0: user”
VNCSERVERARGS  = “-geometry 1024 x 768-depth 16”
1024 x 768-resolution desktop
Not to start a VNC server manually after each reboot, you can add it to the startup procedure. If you wish, you can build a full set of scripts for the upstart, but in practice enough to do without adding to the/etc/rc.local file:
Su user-c-l “vncserver: 0”
Reload the server to check: #reboot
And try to connect to any VNC client, VNC port: 5900, do not forget to add entry-open port 5900 in iptables firewall.
The client can download here http://sourceforge.net/projects/tigervnc/files/tigervnc/1.2.0/
PS: you can do it as root user, but for security reasons, in order not to do better.
