CentOS 防火墙配置 80端口
看了好几个页面内容都有错,下面是正确方法:
#/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
#/sbin/iptables -I INPUT -p tcp --dport 22 -j ACCEPT
然后保存:
#/etc/rc.d/init.d/iptables save
再查看是否已经有了:
#/sbin/iptables -I INPUT -p tcp --dport 80 -j ACCEPT
#/sbin/iptables -I INPUT -p tcp --dport 22 -j ACCEPT
然后保存:
#/etc/rc.d/init.d/iptables save
再查看是否已经有了:
[root@vcentos ~]# /etc/init.d/iptables status
