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

项目开发的过程中，应业务需求将Redis作为缓存服务器整合进了Spring Boot的项目中，在初测试的时候，遇到连接超时的情况，错误信息如下：

解决办法：

一、application.yml的redis配置中的spring.redis.timeout中连接超时时间（毫秒）中时间设置不能为0

二、找到redis的配置文件 redis.conf

vim redis.conf

修改 protected-mode  yes 改为：protected-mode no

注释掉 #bin 127.0.0.1
