异常描述
在云服务器部署了一个redis，启动基本上都是默认参数，然后Spring Boot新建项目配置如下：
spring:
redis:
cluster:
nodes: 192.168.7.8:6379在项目启动的时候，报错：
2020-12-20 22:14:17.780 [ok-cloud-cache-service][ WARN ] [12543] [nio-8101-exec-1] [f72eec5ef3575e8e] [f72eec5ef3575e8e] [true] --- [io.lettuce.core.cluster.topology.ClusterTopologyRefresh] [getNodeSpecificViews] [216] : Cannot retrieve partition view from RedisURI [host='192.168.7.8', port=6379], error: java.util.concurrent.ExecutionException: io.lettuce.core.RedisCommandExecutionException: ERR This instance has cluster support disabled

从报错信息ERR This instance has cluster support disabled很明显看得出来，是没有启动Redis集群功能，可是项目配置的集群方式，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: 192.168.7.8
port: 63792、搭建Redis集群
