Unable to connect to Redis； nested exception is io.lettuce.core.RedisConnectionException: 解决办法

问题：今天测试测流程，发现项目报下面这个错误

Redis exception; nested exception is io.lettuce.core.RedisException: io.lettuce.core.RedisConnectionException: 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.

 错误原因：由于redis的保护模式开启了，并且没有绑定ip地址，没有密码认证

 

 

解决：
 

找到redis的配置文件 redis.conf并编辑

vim redis.conf

1）修改 protected-mode  yes 改为：protected-mode no

2）如果本地可以，部署到服务器上不行，记得把 bind 127.0.0.1 注释。

3）设置密码访问模式，在redis.conf中加入一行密码设置 

  require 你的密码

 

注：记得项目重启，项目重启，项目重启！！！！（就是这个坑了我好长时间）
