Centos下设置VNC为3389端口

1、安装vnc

1. yum install vnc vnc-server

yum install vnc vnc-server

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

1. grep "59" /usr/bin/vncserver -n
2. $vncPort = 5900 + $displayNumber;
3. # (5900+n) or the X server port (6000+n).
4. if (!bind(S, pack('S n x12', $AF_INET, 5900 + $n))) {

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

1. vncserver
2. You will require a password to access your desktops.
3. Password:
4. Verify:

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

4、添加vnc用户，添加/etc/sysconfig/vncservers

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

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

5、配置防火墙，vi /etc/sysconfig/iptables

1. [root@centos63 ssh]# vi /etc/sysconfig/iptables
2. # Firewall configuration written by system-config-firewall
3. # Manual customization of this file is not recommended.
4. *filter
5. :INPUT ACCEPT [0:0]
6. :FORWARD ACCEPT [0:0]
7. :OUTPUT ACCEPT [0:0]
8. -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
9. -A INPUT -p icmp -j ACCEPT
10. -A INPUT -i lo -j ACCEPT
11. -A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
12. -A INPUT -m state --state NEW -m tcp -p tcp --dport 3389 -j ACCEPT
13. -A INPUT -j REJECT --reject-with icmp-host-prohibited
14. -A FORWARD -j REJECT --reject-with icmp-host-prohibited
15. COMMIT

[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

1. /etc/init.d/vncserver restart
2. 或者
3. service vncserver restart

/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

1. /etc/init.d/iptables restart
2. service iptables restart

/etc/init.d/iptables restart
service iptables restart

8、设置vnc服务器开机自动启动

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

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
