我是运行了systemctl stop firewalld.service && systemctl disabl e firewalld.service命令于是显示

[root@instance-x0s3yzhy ~]# systemctl status firewalld.service
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor p reset: enabled)

证明防火墙关闭了

对防火墙的其他操作就看以下博客
