解决idea用 jedis 链接在虚拟机上链接redis 超时问题Exception in thread “main“ redis.clients.jedis.exceptions.

Exception in thread “main” redis.clients.jedis.exceptions.JedisConnectionException: java.net.ConnectException: Connection refused: connect

1.在网上找了不少问题，很大的缘由就是防火墙没有关闭 ,须要输入一下命令便可,本身的电脑上显示关了没有用，必须在虚拟机中输入下面命令

systemctl stop firewalld.service

firewalld防火墙的基本使用

2.注释掉 bind 127.0.0.1或者改为本身的虚拟机地址

三、关闭安全模式: protected-mode no

四、重启虚拟机，redis，而后就能够正常访问了
