#4. 防火墙配置

#a.添加.允许访问端口{21: ftp, 80: http, 3306：mysql}.

iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 80 -j ACCEPT 
iptables -I RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 3306 -j ACCEPT

#b.关闭防火墙{不推荐}.

service iptables stop

#c.重启防火墙

service iptables restart 
#d.永久关闭防火墙{不推荐}.
chkconfig --level 35 iptables off
