VNC的安装配置使用-创新互联
Xmanager Enterprise 4的Xshell和Xstart虽然是客户端连接服务端进行操作，但是真实的操作界面是在客户端，一旦网络中断或客户端出现问题，则操作中断
VNC也是客户端连接服务端进行操作，但是真实的操作界面是在服务端，遇到网络、客户端等问题导致连接中断时，在服务器端运行的东西不会中断
CentOS release 6.5 环境下的安装配置
安装
yum -y install tigervnc-server
或
yum -y install vnc-server
包tigervnc-server-1.1.0-18.el6.x86_64安装好了即可
配置VNC中root密码
[root@fusndb db]# vncserver
You will require a password to access your desktops.
Password:
Verify:
xauth: creating new authority file /root/.Xauthority
New 'fusndb:1 (root)' desktop is fusndb:1
Creating default startup script /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/fusndb:1.log
配置VNC中oracle密码
[root@fusndb db]# su - oracle
[oracle@fusndb ~]$ vncserver
You will require a password to access your desktops.
Password:
Verify:
xauth: creating new authority file /home/oracle/.Xauthority
New 'fusndb:2 (oracle)' desktop is fusndb:2
Creating default startup script /home/oracle/.vnc/xstartup
Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/fusndb:2.log
保存配置信息
vi /etc/sysconfig/vncservers新增一行VNCSERVERS="1:root 2:oracle"
重启vncserver服务
[root@fusndb db]# service vncserver restart
Shutting down VNC server: 1:root 2:oracle [ OK ]
Starting VNC server: 1:root
New 'fusndb:1 (root)' desktop is fusndb:1
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/fusndb:1.log
2:oracle
New 'fusndb:2 (oracle)' desktop is fusndb:2
Starting applications specified in /home/oracle/.vnc/xstartup
Log file is /home/oracle/.vnc/fusndb:2.log
[ OK ]
如下代表服务器端开启了4个VNC进程，分别是IP:1\IP:2\IP:3\IP:4,其中IP:4是在root用户下开启的，其他都是stadium
