Question

我正在尝试运行我的 Spring Boot 应用程序 MongoDB ＆amp; Virtual Box上的 Redis服务器但是收到与redis相关的错误，因此无法完成该过程..我得到这些错误：

我尝试过以下但没有奏效：

Stackoverflow Question

Answer 1

看起来像连接问题，请验证以下内容：

配置不匹配

在redis redis.conf文件中，找到bind config和port default

bind 127.0.0.1
port 6379

JedisConnectionFactory使用的jedis默认值（请参阅堆栈跟踪）是：

bind localhost
port 6379

请参阅jedis客户端Protocol和Spring数据JedisConnectionFactory类。

确保它们符合您的spring-boot应用程序配置如果不使用JedisShardInfo 为了更新你的配置，JedisConnectionFactory在它的约束器中接受JedisShardInfo。

确保/ etc / hosts或c：\ windows \ system32 \ drivers \ etc \ hosts 有条目

127.0.0.1       localhost

Altough微不足道有时候会有人唠叨或删除它。

Redis启动失败

确保您的redis启动并运行可能是另一个进程正在使用redis端口。使用

netstat –anp | grep 6379

或windows

netstat –ano | find “6379”

如果您发现使用端口的其他进程相应调整
