异常描述
新建了一个项目,我自己的服务器安装了一个redis,安装的时候,基本上都是默认参数,然后SpringBoot配置如下:

spring:
  redis:
    cluster:
      nodes: qianxunclub.com:6666

在项目启动的时候,报错:

异常分析
从报错误的信息ERR This instance has cluster support disabled很明显看得出来,是没有启动redis集群功能,可是我项目配置的集群的配置方式,要么修改代码为单机配置,要么修改redis为集群方式。

解决办法
1、可以修改配置为单机redis配置:

spring:
  redis:
    host: qianxunclub.com
    port: 6666

2、在安装redis的目录找到redis配置文件redis.conf,里面会找到配置:

# cluster-enabled yes

把注释去掉就可以了

cluster-enabled yes
