firewalld 指定IP访问某端口
1. 打开firewalld防火墙
systemctl start firewalld.service
2. 添加防火墙规则(对指定ip开放指定端口)
(以下红色字体需要根据实际情况修改)
允许192.168.142.166访问5432端口
firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.142.166" port protocol="tcp" port="11300" accept"
3. 重启防火墙,使配置生效
systemctl restart firewalld.service
4. 查看配置结果,验证配置
firewall-cmd --list-all
5. 删除规则
示例:
firewall-cmd --permanent --remove-rich-rule="rule family="ipv4" source address="192.168.142.166" port protocol="tcp" port="11300" accept"
systemctl restart firewalld.service
