Jedis本地连接Redis哨兵报错：DENIED Redis is running in protected mode because protected mode is enabled

本文主要是介绍Jedis本地连接Redis哨兵报错：DENIED Redis is running in protected mode because protected mode is enabled，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、问题描述

Redis环境可以参考：https://blog.csdn.net/u010886217/article/details/104664357

Centos6搭建Redis集群，并且用3哨兵监控一个主节点。环境没有问题，在linux可以连接

[root@bigdata redis-3.2.0]# redis-cli -h 192.168.0.9 -p 26379 
192.168.0.9:26379> 

但是在本地调试，使用jedis连接哨兵的时候，报错：

主要信息如下：
-DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.   

二、问题原因

问题原因，在信息里面很清楚，也参考了很多博客，只是无从下手。尝试方法
1.修改redis.conf配置文件，修改protected-mode yes为protected-mode no。重启redis服务，但是无效，依旧报同样错误。
2.修改sentinel_26379.conf，添加sentinel announce-ip 192.168.0.9。依旧无效
比较纠结，问题解决方法，信息里面都有，就是比较难找到。最终，尝试：
3.修改sentinel_26379.conf配置文件，添加protected-mode no，后续不报这个错误了。所以基本问题也解决了。【不过，神奇的是protected-mode no在哨兵配置文件时没有的。】

三、解决办法

1.修改redis.config

protected-mode no

2.修改哨兵配置文件sentinel_26379.conf，添加

protected-mode no

3.重启redis服务和哨兵服务

4.jedis可以解决这个jedis连接错误
