重启防火墙（iptables)命令#service iptable restart失效

Redirecting to /bin/systemctl restart iptables.ser

linux下执行防火墙相关指令报错：

Redirecting to /bin/systemctl restart iptables.service

1，安装systemctl：

yum install iptables-services

2，设置开机启动：

systemctl enable iptables.service

然后就可以执行以下指令了：

systemctl stop iptables
systemctl start iptables
systemctl restart iptables
systemctl reload iptables
