CentOS7 关闭防火墙

1 查看防火墙状态

[root@centos01 ~]# firewall-cmd --state

running

2 果然是运行的，于是就想disabled防火墙服务

[root@centos01 ~]# systemctl mask firewalld

ln -s '/dev/null' '/etc/systemd/system/firewalld.service'

3 然后关闭防火墙

systemctl stop firewalld.service #停止firewall

systemctl disable firewalld.service #禁止firewall开机启动

4.启动防火墙

systemctl start firewalld.service #停止firewall
