VNC is a protocol that is used to share the desktop with other users/computers over the network/Internet.In order to share a desktop, VNC server must be install and configure on the computer and VNC client must be run on the computer that will access the shared desktop.

When we install the minimal copy of CentOS Server, it only gives us the “Command Line” interface.
But some people prefer GUI instead and for this they install Full version of Gnome on CentOS. Actually there is a better way and that is to install VNC. VNC provides a lightweight virtual desktop than full blown version of Gnome.

To run the VNC Server on CentOS, we have to install these required packages:
sudo yum groupinstall Desktop
sudo yum install tigervnc-server
sudo yum install xorg-x11-fonts-Type1

This is optional:
sudo yum install vnc

To start VNC Server on boot
sudo chkconfig vncserver on
To setup users’ VNC password:

vncpasswd
Edit the /etc/sysconfig/vncservers file:
sudo nano /etc/sysconfig/vncservers

Add the following to the end of the file:
VNCSERVERS=“1:root”
VNCSERVERARGS[1]="-geometry 1024x600"

The iptables rules need to be amended to open the VNC ports:
sudo iptables -I INPUT 5 -m state --state NEW -m tcp -p tcp -m multiport --dports 5901:5903,6001:6003 -j ACCEPT 去掉5后运行正常
sudo service iptables save
sudo service iptables restart

Restart the VNC Server:
sudo service vncserver restart

Now kill the VNC Server:
vncserver -kill :1

Edit the xstartup file in .vnc directory:
nano .vnc/xstartup

Comment the last line and run the Gnome:
#twm &
exec gnome-session & 有的文件中不存在这一行

Restart the service:
sudo service vncserver restart

sudo service vncserver stop 关闭服务后节省资源

编辑 /etc/inittab 给设定启动cli还是gui
