解决方法

停止 firewalld

安装 iptables-services

[root@Jaking ~]# yum install -y iptables-services

开启 iptables

[root@Jaking ~]# service iptables start
Redirecting to /bin/systemctl start iptables.service

还可以使用 systemctl 来控制 iptables

systemctl [start|status|stop|restart|enable] iptables

把 iptables 加到开机启动项中

[root@Jaking ~]# systemctl enable iptables

清空防火墙

[root@Jaking ~]# iptables -F

保存防火墙规则

[root@Jaking ~]# service iptables save

# 或者
[root@Jaking ~]# /usr/libexec/iptables/iptables.init save
