## 防火墙规则
 防火墙规则添加：针对单独的ip+端口
示例：
添加：
firewall-cmd --permanent --zone=external --add-rich-rule="rule family="ipv4" source address="2.0.0.22" port protocol="tcp" port="3307" accept"
删除：
firewall-cmd --permanent --zone=external --remove-rich-rule="rule family="ipv4" source address="2.0.0.22" port protocol="tcp" port="3307" accept"
