1. 检查vnc客户端和服务器是否已经安装：
[gavin@centos ~]$ rpm -q vnc vnc-server
package vnc is not installed
vnc-server-4.0-8.1
cent os 5已包含vnc的安装包
2. 将用户名称加入到配置文件：
(注：这里的“用户名”是指linux系统用户的名称)
[gavin@centos ~]# vi /etc/sysconfig/vncservers
#
# Uncomment the line below to start a VNC server on display :1
# 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
# /vnc/sshvnc.html>.
# VNCSERVERS="1:myusername"
# VNCSERVERS="1:gavin 2:john" # use the method for more user
VNCSERVERS="1:gavin 2:root 3:root"
# VNCSERVERARGS[1]="-geometry 800x600"
VNCSERVERARGS[1]="-geometry 1024x768"
3. 设置用户gavin的密码
[gavin@centos ~]$ vncpasswd
Password:
Verify:
4. 启动VNC服务
[gavin@centos ~]# /sbin/service vncserver start
Starting VNC server: 1:gavin [ OK ]
5. 输入命令
[gavin@centos ~]$ cd ~/.vnc/
[gavin@centos .vnc]$ vi 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" &
gnome-session & #set starting GNOME desktop
#startkde & #kde desktop
#twm & #Text interface
6. 重启vncserver
[gavin@centos ~]# /sbin/service vncserver restart
Shutting down VNC server: 1:gavin [ OK ]
Starting VNC server: 1:gavin [ OK ]
7. Windows登陆到VNC Server
(1).从IE登录
直接从IE浏览器中输入如下地址：
http://xxx.xxx.xxx.xxx:5802
输入密码即可使用。
(2).从VNC view登录
在windows上安装vnc view，然后输入xxx.xxx.xxx.xxx:5901，连接登录，输入密码即可。
备注：如果从vnc view登录时，提示connection refused(10061)，则是因为linux防火墙的问题，登录centos系统，选择System-->Preferences-->Remote Desktop，勾选sharing中的两项，Security两项不勾，点击关闭，然后再重新用vnc view登录即可。
iptables -F清除防火墙策略，就是关闭防火墙
如果还不好，修改
usr001@ myhost ~]$ vncserver
You will require a password to access your desktops.

VNC默认启动的X－windows是twm，很不好看，配置在/root/.vnc/xstartup
[usr001@ myhost ~]$ vim .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 &
bash &
gnome-session &
fcitx &
启动vncserver ，
# vncserver :1 -geometry 1024x768 -depth 24
或者
#vncserver :1
如果要在用户登录时就加载vncserver服务，可以在~/.bash_profile加入下面这行：
vncserver :1 -geometry 1024x768 -depth 24 &
关闭vncserver服务：
[usr001@myhost ~]$ vncserver -kill :1
初次启动vncserver时，已经设置了连接密码，下面命令可以用来修改连接密码：
# vncpasswd
Password:
Verify:
VNC用起来感觉比Xmanager快很多
