Centos7关闭防火墙
今天在centos上想要关闭防火墙,查了一些博客,执行命令
systemctl status firewalld.service
时报错Unit firewalld.service could not be found.
然后查了很多资料都说执行下面这个就解决了
systemctl unmask firewalld.service
然而又报错了
Failed to start firewalld.service: Unit not found.
太头疼了,百度千篇一律的答案始终无法解决,
最后终于找到问题
其实就是要排除你们是否安装了这个firewalld
yum install firewalld
systemctl unmask firewalld
systemctl enable firewalld
systemctl start firewalld
依次执行以上命令后发现终于ok了
其他命令
systemctl start firewalld.service //开启防火墙
systemctl stop firewalld.service //关闭防火墙
systemctl enable firewalld.service //设置开机自动启动
systemctl disable firewalld.service //设置关闭开机制动启动
firewall-cmd --reload //在不改变状态的条件下重新加载防火墙
终于解决了,世界安静了!
