1.確認有安裝vnc
[root@Linux1 root]# rpm -qa |grep vnc
vnc-server-3.3.3r2-18.6
vnc-3.3.3r2-18.6
[root@Linux1 root]#

2.設置vncserver為開機自啟動
[root@Linux1 root]#setup

choose [vncserver] ==>Tab [OK] ==>Tab [Quit]

3.切換到要使用vnc的user account下找到xstartup這個文件（for e.g. root）
[root@Linux1 .vnc]# pwd
/root/.vnc
[root@Linux1 .vnc]# ls xstartup
xstartup
[root@Linux1 .vnc]#

4.修改xstartup這個文件讓在用vnc連到server是顯示為KDE or GNOME
  vncserver default開啟的是XDM
[root@Linux1 .vnc]# vi xstartup

#!/bin/sh

#xrdb $HOME/.Xresources
#xsetroot -solid grey
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
#exec /etc/X11/xinit/xinitrc

#add by vongates for gnome
gnome-session
#if you use KDE,Please add follow line
#startkde
#add end
~
5.啟動VNC
[root@Linux1 .vnc]# vncserver

New 'X' desktop is Linux1.com.cn:1

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/Linux1.com.cn:1.log

[root@Linux1 .vnc]# vncserver

Warning: Linux1.com.cn:2 is taken because of /tmp/.X11-unix/X2
Remove this file if there is no X server Linux1.com.cn:2

New 'X' desktop is Linux1.com.cn:3

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/Linux1.com.cn:3.log

[root@Linux1 .vnc]# ps -aux |grep vnc
root     24930  0.2  0.1  5660 3540 pts/2    S    13:08   0:00 Xvnc :1 -desktop
root     25124  0.2  0.1  4880 3100 pts/2    S    13:09   0:00 Xvnc :3 -desktop
root     25479  0.0  0.0  1740  600 pts/2    S    13:12   0:00 grep vnc
[root@Linux1 .vnc]#

6.關閉VNC
[root@Linux1 .vnc]# vncserver -kill :1
Killing Xvnc process ID 24930
[root@Linux1 .vnc]# vncserver -kill :3
Killing Xvnc process ID 25124
[root@Linux1 .vnc]# ps -aux |grep vnc
root     25497  0.0  0.0  1736  588 pts/2    S    13:13   0:00 grep vnc
[root@Linux1 .vnc]#

7.變更vncserver的密碼
[root@Linux1 .vnc]# vncpasswd
Password:
Verify:
[root@Linux1 .vnc]#

8.vncserver --help
[root@Linux1 .vnc]# vncserver --help

usage: vncserver [:] [-name ] [-depth ]
                 [-geometry x]
                 [-pixelformat rgbNNN|bgrNNN]
                 ...

       vncserver -kill

[root@Linux1 .vnc]#

9.VNC Client如何連接上server
a.)
b.)在windows下的通過vncview這個應用程式
c.)在Linux下的run中輸入vncviewer
