1丶配置安装VNC
[root@guodb2 Disk1]# yum install vnc*
2丶设VNC密码[root@guodb2 Disk1]# vncserver
You will require a password to access your desktops.
Password:
Verify:
New \'guodb2:1 (root)\' desktop is guodb2:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/guodb2:1.log
3丶重新启动VNC服务[root@guodb2 Disk1]# service vncserver stop
Shutting down VNC server: [ OK ]
[root@guodb2 Disk1]# service vncserver start
Starting VNC server: no displays configured [ OK ]
4丶登录报错如下
5丶查VNC端口[root@guodb2 Disk1]# netstat -tupln |grep vnc
tcp 0 0 0.0.0.0:6001 0.0.0.0:* LISTEN 9748/Xvnc
tcp 0 0 0.0.0.0:5801 0.0.0.0:* LISTEN 9748/Xvnc
tcp 0 0 0.0.0.0:5901 0.0.0.0:* LISTEN 9748/Xvnc
6丶从上面可以看出0号端号被占用了，用1号端号登录
7丶正常登录VNC，但图形界面显示如下 
8丶修改VNC配置文件，注释原来的两行，添加最后两行[root@guodb2 Disk1]# vi /etc/sysconfig/vncservers
# VNCSERVERS="2:myusername"
# VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost" VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1400x750 -nolisten tcp "
9丶修改图形界面,全部注释掉，添加最后一行[root@guodb1 yum.repos.d]# vi /root/.vnc/xstartup
#!/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 &
gnome-session &10丶重启VNC服务[root@guodb2 Disk1]# service vncserver stop
Shutting down VNC server: 1:root [ OK ]
[root@guodb2 Disk1]# service vncserver start
Starting VNC server: 1:root xauth: creating new authority file /root/.Xauthority
New \'guodb2:1 (root)\' desktop is guodb2:1
