# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the lines below to start a VNC server on display :
# 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 this URL:
# http://kbase.redhat.com/faq/docs/DOC-7028 # Use "-nolisten tcp" to prevent X connections to your VNC server via TCP. # Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel. See the "-via" option in the
# `man vncviewer' manual page.

root@localhost /]#su wt
[huilin@localhost /]$ vncserver :2
You will require a password to access your desktops.
Password: 输入vnc 连接密码
Verify: 确认vnc密码
xauth: creating new authority file /home/huilin/.Xauthority
New 'localhost.localdomain:2 (huilin)' desktop is localhost.localdomain:2
Creating default startup script /home/huilin/.vnc/xstartup
Starting applications specified in /home/huilin/.vnc/xstartup
Log file is /home/huilin/.vnc/localhost.localdomain:2.log
* 注意到每个用户都可以启动自己的 vncserver，每个用户可以启动多个 vncserver，
用ip加端口号 ip:1，ip:2，ip:3 来标识。vncserver的大部分配置文件及日志文件都在用户home目录下.vnc目录下
用户可以自定义启动号码如：
[huilin@localhost /]$ vncserver
A VNC server is already running as :1
3、打开对应的端口
打开5901至5902 端口用于vnc //如果需要配置更多的桌面，增加端口即可
iptables -I INPUT -p tcp --dport 5901:5902 -j ACCEPT
iptables -A INPUT -p tcp --dport 5901:5902 -j ACCEPT
永久保存
service iptables save
4.启动vncserver服务
1）启动全部桌面
service vncserver start
2）启动某一桌面
vncserver :1 //这里1表示第一个桌面
5、停止vncserver服务
1）停止全部桌面
service vncserver stop
2) 停止某一桌面
vncserver -kill :1 //停止第1个界面，要用kill命令来杀掉界面1的进程
6、查看当前有几个桌面在运行
service vncserver status
7、让vncserver服务随机启动
默认状态下，vncserver服务不是开机自动启动，需要手工启动。
chkconfig --list vncserver
chkconfig vncserver on
保存后，重启测试。
8.客户端登录vncserver服务
（1）先安装vncviewer来远程登录，
（2）然后在地址栏输入“主机地址:1”（即主机IP加界面号的方式）
