Centos上设置VNC为3389端口

Centos下设置VNC为3389端口
1、安装vnc

yum install vnc vnc-server

2、修改vnc端口，修改/usr/bin/vncserver ，把5900变为3388

grep "59" /usr/bin/vncserver -n$vncPort = 5900 + $displayNumber;# (5900+n) or the X server port (6000+n).    if (!bind(S, pack('S n x12', $AF_INET, 5900 + $n))) {

3、启动VNC服务

vncserverYou will require a password to access your desktops.Password:Verify:

4、添加vnc用户，添加/etc/sysconfig/vncservers

VNCSERVERS="1:root"VNCSERVERARGS[1]="-geometry 1024x768"

5、配置防火墙，vi /etc/sysconfig/iptables

[root@centos63 ssh]# vi /etc/sysconfig/iptables# Firewall configuration written by system-config-firewall# Manual customization of this file is not recommended.*filter:INPUT ACCEPT [0:0]:FORWARD ACCEPT [0:0]:OUTPUT ACCEPT [0:0]-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT-A INPUT -p icmp -j ACCEPT-A INPUT -i lo -j ACCEPT-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT[b]-A INPUT -m state --state NEW -m tcp -p tcp --dport 3389 -j ACCEPT[/b]-A INPUT -j REJECT --reject-with icmp-host-prohibited-A FORWARD -j REJECT --reject-with icmp-host-prohibitedCOMMIT

6、重启VNC服务

/etc/init.d/vncserver restart或者service vncserver restart

7、重启防火墙，使刚才的端口配置生效

/etc/init.d/iptables restartservice iptables restart

8、设置vnc服务器开机自动启动

chkconfig vncserver onchkconfig --list vncservervncserver       0:off   1:off   2:on    3:on    4:on    5:on    6:off

9、远程登录
