Linux學習筆記CentOS 6.5（十）---Mysql防火牆開放3306埠
防火牆開放3306埠
1、開啟防火牆配置檔案
vi /etc/sysconfig/iptables
2、增加下面一行
-A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
3、更改後的防火牆配置檔案
# 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 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
4、儲存後重啟防火牆
service iptables restart
注意：增加的開放3306埠的語句一定要在icmp-host-prohibited之前，否則將仍不能進行訪問。
