VNC是一款遠程控制工具，免費的開源軟件，通過VNC能夠實現強大的遠程控制，且是Linux有圖形化的操作界面，下面小編就以CentOS 6.3為例，給大家介紹下VNC在CentOS 6.3下的安裝和配置。
1，安裝GNOME桌面環境
［root@ www.linuxidc.com ~］# yum -y groupinstall “GNOME Desktop Environment”
2， 安裝KDE桌面環境
［root@ www.linuxidc.com ~］# yum groupinstall “X Window System” “KDE （K Desktop Environment）”
3，安裝VNC服務器
［root@ www.linuxidc.com ~］# yum -y install vnc-server

4，配置VNC
［root@ www.linuxidc.com ~］# su -jackiebui
［jackiebui@tanvps ~］# vncpasswd
Password：******
verify：******
［jackiebui@tanvps ~］# ls .vnc/
5，編輯VNC配置文件
［root@ www.linuxidc.com ~］# 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
啟動VNC
［root@ www.linuxidc.com ~］# vncserver
［root@ www.linuxidc.com ~］# chkconfig vncserver on //設置為開機啟動
上面就是CentOS6.3安裝設置VNC的方法介紹了，在安裝VNC前，需要先安裝GNOME、KDE桌面環境，安裝完VNC後需要對其進行相關配置。
