vncserver修改启动端口为1521

修改端口：
[root@oracle net]# vim /usr/bin/vncserver
[root@oracle net]# 
222 #$vncPort = 5900 + $displayNumber;
223 $vncPort = 1520 + $displayNumber;


再重启vncserver：
[root@oracle net]# service vncserver restart
Shutting down VNC server: 1:root                           [  OK  ]
Starting VNC server: 1:root 
New 'pldb1:1 (root)' desktop is pldb1:1


Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/pldb1:1.log


                                                           [  OK  ]

[root@oracle net]# 

查看日志，看到启用的是1521端口
[root@oracle net]# tail -fn 3000 /root/.vnc/pldb1:1.log
