centos 7_CentOS 中VPS开启80端口方法

【www.bbyears.com--CentOS】

CentOS 防火墙开启80端口

#/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

注意需要重启服务哦：执行service iptabels save 与 service iptables restart

端口查看方法:

vhost]# /etc/init.d/iptables status
Table: filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80
2 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80

Chain FORWARD (policy ACCEPT)
num target prot opt source destination

Chain OUTPUT (policy ACCEPT)
