Linux防火墙添加白名单

查看防火墙状态

systemctl status firewalld

开启防火墙

systemctl start firewalld.service

开机启动防火墙

systemctl enable firewalld.service

关闭防火墙

systemctl stop firewalld.service

禁止开机自启

systemctl disable firewalld.service

白名单配置如下：

新增防火墙规则（允许指定ip访问指定端口）：

firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.10.101" port protocol="tcp" port="8099" accept"

删除防火墙规则：

firewall-cmd --permanent --remove-rich-rule="rule family="ipv4" source address="192.168.10.101" port protocol="tcp" port="8099" accept"

允许10.55.39.75访问所有端口（允许指定ip访问所有端口）

firewall-cmd --zone=public --add-rich-rule 'rule family="ipv4" source address="10.55.39.75" accept' --permanent

移除10.55.39.75访问所有端口

firewall-cmd --zone=public --remove-rich-rule 'rule family="ipv4" source address="10.55.39.75" accept' --permanent

执行reload

firewall-cmd --reload

设置完规则后执行如下命令，查看防火墙规则，查看设置是否已添加

firewall-cmd --list-all

如若没生效重启防火墙

systemctl restart firewalld.service
