《centos7如何去掉firewalld改用Iptables命令？》要点：
本文介绍了centos7如何去掉firewalld改用Iptables命令？，希望对您有用。如果有疑问，可以联系我们。
centos 7默认是用firewalld，那如何改为Iptables防火墙？
centos 7中不可执行： # service iptables save
[root@VM_0_6_centos ~]# 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.
解决方法：
1.先执行如下命令：
systemctl stop firewalld
systemctl mask firewalld
2.安装iptables services
yum -y install iptables-services
3.设置开机启动
systemctl enable iptables
4.重启iptables service
systemctl restart iptables
命令：systemctl [stop|start|restart] iptables
5.执行保存配置命令
service iptables save
