1、代码

Jedis jedis = new Jedis("192.168.88.151",6379);

2、开启6379端口

//查看6379端口是否开启--yes是开启；no是关闭
firewall-cmd --query-port=6379/tcp

//开启6379端口
firewall-cmd --zone=public --add-port=6379/tcp --permanent

//重启使生效
firewall-cmd --reload

//再次查看6379端口是否成功开启
firewall-cmd --query-port=6379/tcp

//查看已经开启的端口
firewall-cmd --list-ports

3、关闭防火墙

//查看防火墙状态
systemctl status firewalld

//关闭防火墙
systemctl stop firewalld

//查看是否正确关闭防火墙
systemctl status firewalld

然后就能够正确连接到啦~~~~
