1、查看防火墙端口列表
firewall-cmd --list-ports
2、添加指定端口tcp
firewall-cmd --zone=public --add-port=8080/tcp --permanent　#开放8080/tcp端口　

firewall-cmd --zone=public --add-port=10002-10010/tcp --permanent　　#开放10002-10010/tcp端口范围

添加指定端口udp

firewall-cmd --zone=public --add-port=9200/udp --permanent　　　　　　#开放9200/udp端口
firewall-cmd --zone=public --add-port=20015-20020/udp --permanent　　#开放20015-20020/udp端口范围

3、删除指定端口

firewall-cmd --zone= public --remove-port=19800/tcp --permanent　　　　#删除已开放的19880/tcp端口

firewall-cmd --zone= public --remove-port=9200-9300/udp --permanent　　#删除已开放的9200-9300/udp 端口范围
4、热加载防火墙，使之生效
firewall-cmd --reload

5、指定某IP访问某端口
firewall-cmd --permanent --zone=public --add-rich-rule="rule family="ipv4" source address="192.168.0.107" port protocol="tcp" port="3306" accept"

删除策略

firewall-cmd --permanent --zone=public --remove-rich-rule="rule family="ipv4" source address="192.168.0.107" port protocol="tcp" port="3306" accept"

6、指定某个网段访问某个端口范围
firewall-cmd --permanent --zone=public --add-rich-rule="rule family="ipv4" source address="11.76.168.0/24" port protocol="udp" port="1-65535" accept"

删除策略

firewall-cmd --permanent --zone=public --remove-rich-rule="rule family="ipv4" source address="11.76.168.0/24" port protocol="tcp" port="1-65535" accept"
