首先安装tigervnc-server:

yum install tigervnc-server

 

安装好后，设置 vi /etc/sysconfig/vncservers

[root@gateway-001 ~]# cat /etc/sysconfig/vncservers # The VNCSERVERS variable is a list of display:user pairs.## Uncomment the lines below to start a VNC server on display :2# as my 'myusername' (adjust this to your own).  You will also# need to set a VNC password; run 'man vncpasswd' to see how# to do that.  ## DO NOT RUN THIS SERVICE if your local area network is# untrusted!  For a secure way of using VNC, see this URL:# https://access.redhat.com/knowledge/solutions/7027# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.# Use "-localhost" to prevent remote VNC clients connecting except when# doing so through a secure tunnel.  See the "-via" option in the# `man vncviewer' manual page.VNCSERVERS="1:root"VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"VNCSERVERS="2:work"VNCSERVERARGS[2]="-geometry 1024x768  -nolisten tcp -localhost"

 

 

启动vncserver服务器：

[root@gateway-001 ~]# service vncserver start

切换到work用户，设置vncpasswd

在服务器上可以看到打开的vnc端口：

 

 

 

在windows上安装viewvnc，输入ip地址和端口号进行连接：

 

输入密码：

可以看到成功的连接上了centos 6.5的桌面：
