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

vncserver

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
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3389 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT

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 restart
service iptables restart

8、设置vnc服务器开机自动启动

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

9、远程登录
