vi /etc/sysconfig/iptables
-A INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT(允许80端口通过防火墙)
-A INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT(允许3306端口通过防火墙)
特别提示:
很多网友把这两条规则添加到防火墙配置的最后一行,导致防火墙启动失败,正确的应该是添加到默认的22端口这条规则的下面
添加好之后防火墙规则如下所示:
######################################
# 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 80 -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
#####################################
/etc/init.d/iptables restart
#最后重启防火墙使配置生效
本文主要是记录一下可能遇到的问题,由于本人就遇到了该问题,把新添加的规则放到了配置文件的最后一行, 导致mysql无法远程访问,以此笔记。
