1、系統軟件設置
CentOS端：
查看是否安裝了vnc軟件
# rpm -q vnc vnc-server
package vnc is not installed
vnc-server-4.1.2-14.e15_3.1
上面信息就是說，vnc沒有安裝，而vnc-server已經安裝了。
那麼，安裝 vc
# yum install vnc
如果vnc-server沒有安裝，那麼
# yum install vnc-server
Ubuntu端：
安裝vnc4server
$ sudo apt-get install vnc4server
設置密碼
$ vncpasswd
password:
verify:
$ 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 $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
x-window-manager &
修改之後是：
注釋最後兩行，也就是在前面加 #
#x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#x-window-manager &
然後加上
gnome-session &
$ vnc4server
