8.配置VNC系统及分辨率

vi /etc/sysconfig/vncservers

然后在内容中添加

VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1024x768"

上面的分辨率可以根据我们自己的需要修改，比如可以改成800x600等。
9.设置VNC密码 vncserver

[root@server1 ~]#  vncserver

You will require a password to access your desktops.

Password:
Verify:
xauth:  file /root/.Xauthority does not exist

New 'server1.52chenqi.cn:1 (root)' desktop is server1.52chenqi.cn:1

Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/server1.52chenqi.cn:1.log

10.修改xstartup配置文件

vi /root/.vnc/xstartup

所有内容都替换成：

#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
#exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop"&
#twm &
startxfce4 &

11.设置权限以及重启VNC/设置开机启动

service vncserver restart
chkconfig vncserver on
