1、配置并开启vnc服务

[Oracle@localhost ~]$ vncserver

You will require a password to access your desktops.

Password:              ---这里要求输入vnc客户端登录的密码并重复
Verify:              

New 'localhost.localdomain:2 (oracle)' desktop is localhost.localdomain:2

Creating default startup script. /home/oracle/.vnc/xstartup
Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/localhost.localdomain:2.log
  ----如上告诉你vnc终端已经创建好，用的是第二个终端

2、在创建vnc服务的用户目录下会生成一个.vnc的隐藏目录
[oracle@localhost ~]$ ls -a
.              .bash_profile  Disk1     .gconfd          .gstreamer-0.10    .metacity                        README.htm  .viminfo
..             .bashrc        .eggcups  .gnome           .gtkrc-1.2-gnome2  .mozilla                         .RedHat     .vnc
.bash_history  .chewing       .emacs    .gnome2          .ICEauthority      .nautilus                        .scim       .Xauthority
.bash_logout   Desktop        .gconf    .gnome2_private  .kde               p8202632_10205_Linux-x86-64.zip  .Trash      .zshrc

3、进入.vnc目录，找到xstartup可执行文件，用vi 编辑器打开
[oracle@localhost ~]$ cd .vnc/
[oracle@localhost .vnc]$ ls
localhost.localdomain:2.log  localhost.localdomain:2.pid  passwd  xstartup
[oracle@localhost .vnc]$ vi xstartup
#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
 exec /etc/X11/xinit/xinitrc                                          ---去掉前面的#号即可  --保存退出

[ -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 &
~
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
"xstartup" 12L, 333C 已写入                                                                                                              
[oracle@localhost .vnc]$ vncserver

New 'localhost.localdomain:3 (oracle)' desktop is localhost.localdomain:3

Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/localhost.localdomain:3.log

4、清除刚才创建的vnc虚拟终端
[oracle@localhost .vnc]$ vncserver  -kill :1

Can't find file /home/oracle/.vnc/localhost.localdomain:1.pid
You'll have to kill the Xvnc process manually

[oracle@localhost .vnc]$ vncserver  -kill :2
Killing Xvnc process ID 11889
[oracle@localhost .vnc]$ vncserver  -kill :3
Killing Xvnc process ID 11945
[oracle@localhost .vnc]$ vncserver  -kill :4

Can't find file /home/oracle/.vnc/localhost.localdomain:4.pid
You'll have to kill the Xvnc process manually

5、重新建立新的vnc虚拟终端
[oracle@localhost .vnc]$ vncserver

New 'localhost.localdomain:2 (oracle)' desktop is localhost.localdomain:2

Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/localhost.localdomain:2.log              --该终端号为 :2

6、在windows客户端用RealVNC软件中的Run VNC Viewer客户端连接。
7、在Run VNC Viewer  只需输入linux服务器的地址和刚才生成的终端号:2
   格式：192.168.1.56:2
8、输入刚才配置vnc服务的时候配的即可登录linux服务器图形界面。
