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)


(1) Postgresql端口设置。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="5432" accept"


(2)redis端口设置。允许192.168.142.166访问6379端口


firewall-cmd --permanent --add-rich-rule="rule family="ipv4" source address="192.168.142.166" port protocol="tcp" port="6379" accept"

(3)beanstalkd端口设置。允许192.168.142.166访问11300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
