CentOS7关闭防火墙命令_centos7 iptables关闭

CentOS 6 关闭防火墙使用以下命令：

 //临时关闭防火墙
service iptables stop
//禁止开机启动
chkconfig iptables off
//允许开机启动
chkconfig iptables on
//启动防火墙
service iptables start
//重启防火墙
service iptables restart
//查询防火墙状态
service iptables status

CentOS 7 中若使用同样的命令会报错：

[root@localhost ~]# service iptables stop
Redirecting to /bin/systemctl stop iptables.service
Failed to stop iptables.service: Unit iptables.service not loaded.
 

 这是因为CentOS7版本后防火墙默认使用firewalld，因此在CentOS7中操作防火墙使用以下命令：

//查看状态
systemctl status firewalld
//临时关闭
systemctl stop firewalld
//开启防火墙
systemctl start firewalld
//允许开机启动
systemctl enable firewalld
//禁止开机启动
systemctl disable firewalld
