在运维的工作过程中，有时候需要我们用VNC去连接Linux服务器，比如：财务装个金蝶的财务软件，而且还要求放在机房。这个变态的软件在启动的时候，需要我们去点击它的图形界面去启动它。这时，VNC就派上用场了。

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.启动

[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.查看进程：

[root@demo ~]# netstat -ntupl|grep vnc
