使用命令的方式配置

##Add
firewall-cmd --permanent --zone=public --add-port=80/tcp
##Remove
firewall-cmd --permanent --zone=public --remove-port=80/tcp
##Reload

檢查是否生效

firewall-cmd --zone=public --query-port=80/tcp

列出全部的開放端口

firewall-cmd --list-all

查看防火牆狀態

systemctl status firewalld.service

啓動防火牆

systemctl start firewalld.service

關閉防火牆

systemctl stop firewalld.service

從新啓動防火牆

systemctl restart firewalld.service
