解决service iptables save出错please try to use systemctl

　　

# service iptables save
The service command supports only basic LSB actions (start, stop, restart, try-restart, reload, force-reload, status). For other actions, please try to use systemctl.

出错信息如上所示

解决方案:

首先停止防火墙

systemctl stop firewalld
systemctl mask firewalld

然后安装iptables-services

yum install iptables-services

设置开机启动防火墙

systemctl enable iptables

可以使用下面命令管理iptables

systemctl [stop|start|restart] iptables

这时可以保存防火墙规则了

service iptables save
or
/usr/libexec/iptables/iptables.init save

 如果你之后要使用firewall的话：

　　执行命令，即可实现取消服务的锁定

　　# systemctl unmask firewalld

　　下次需要锁定该服务时执行

　　# systemctl mask firewalld
