在運維的工作過程中，有時候需要我們用VNC去連接Linux服務器，比如：財務裝個金蝶的財務軟件，而且還要求放在機房。這個變態的軟件在啓動的時候，需要我們去點擊它的圖形界面去啓動它。這時，VNC就派上用場了。
一.配置文件
# 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
# <URL:http://www.uk.research.att.com/archive/vnc/sshvnc.html>.
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
# Use "-nohttpd" to prevent web-based VNC clients connecting.
# 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="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"
VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 800x600"
二.啓動
[root@demo ~]# /etc/init.d/vncserver restart
Shutting down VNC server: 1:root [ OK ]
Starting VNC server: 1:root
New 'demo:1 (root)' desktop is demo:1
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/demo:1.log
[ OK ]
2.查看進程：
[root@demo ~]# netstat -ntupl|grep vnc
tcp 0 0 0.0.0.0:5801 0.0.0.0:* LISTEN 25350/Xvnc
