1.停止禁用firewall
- systemctl stop firewalld.service
- systemctl disable firewalld.service
2.查看当前firewall状态
- firewall-cmd --state
3.安装iptables-services
- yum install iptables-services
4.修改防火墙配置文件
- vi /etc/sysconfig/iptables
- #示例：增加Redis默认端口
- -A INPUT -p tcp -m state --state NEW -m tcp --dport 6379 -j ACCEPT
5.重启防火墙使配置生效
- service redis -p 6381 start #启动6381端口实例的redis
- /etc/init.d/redis start #默认启动6379端口实例的redis
