重啟防火牆（iptables)命令#service iptable restart失效

Redirecting to /bin/systemctl restart iptables.ser

linux下執行防火牆相關指令報錯：

Redirecting to /bin/systemctl restart iptables.service

1，安裝systemctl：

yum install iptables-services

2，設置開機啟動：

systemctl enable iptables.service

然后就可以執行以下指令了：

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