对于用惯了WIN系统的朋友来说，没有图形化操作界面的Linux用起来实在太难受了。实际上，Linux也是有图形化操作界面的，这就是VNC。接下来本文将告诉大家如何在CentOS 6.3下安装和配置 VNC图形化操作界面。

1，安装GNOME桌面环境

[root@ www.it.net.cn ~]# yum -y groupinstall “GNOME Desktop Environment”
 
2， 安装KDE桌面环境

[root@ www.it.net.cn ~]# yum groupinstall “X Window System” “KDE (K Desktop Environment)”
 
3，安装VNC服务器

[root@ www.www.it.net.cn ~]# yum -y install vnc-server

Complete!
 [root@ www.it.net.cn ~]#
 
4,配置VNC

[root@ www.it.net.cn ~]# su -jackiebui
 [jackiebui@tanvps ~]# vncpasswd
 Password:******
 verify:******
 [jackiebui@tanvps ~]# ls .vnc/
 
5,编辑VNC配置文件
 

[root@ www.it.net.cn ~]# vi /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:
 # http://kbase.RedHat.com/faq/docs/DOC-7028
 
# 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:jackiebui” //Uncomment 2 last lines, and edit your VNC user
 VNCSERVERARGS[2]=”-geometry 800×600 -nolisten tcp -localhost” // Save and exit
 
启动VNC

[root@ www.it.net.cn ~]# vncserver
[root@ www.it.net.cn ~]# chkconfig vncserver on //设置为开机启动
