Linux报错：Redirecting to /bin/systemctl status iptables.service Unit iptables.service could not be fou

centos查看防火墙状态时报错

service iptables status

报错提示：

Redirecting to /bin/systemctl status iptables.service
Unit iptables.service could not be found.

解决办法：

yum install iptables-services

下载完成之后重新运行，出现下面的代码，即证明可用了

[root@VM-0-16-centos ~]# service iptables status
Redirecting to /bin/systemctl status iptables.service
