连接Redis集群报 Unable to connect to 127.0.0.1:7008

错误现象
application.yaml中配置如下

spring:
  cache:
    type: redis
    redis:
      time-to-live: 60000
  redis:
    cluster:
      max-redirects: 3
      nodes:
      - 10.10.4.248:7001
      - 10.10.4.248:7002
      - 10.10.4.248:7003
      - 10.10.4.248:7004
      - 10.10.4.248:7005
      - 10.10.4.248:7006
      - 10.10.4.248:7007
      - 10.10.4.248:7008
      - 10.10.4.248:7009

使用时出现如下描述

错误原因
集群配置错误，创建集群时应该使用客户端可以访问到的IP地址（而不是使用127.0.0.1），示例

redis-trib.rb create --replicas 1 10.10.4.248:7001 10.10.4.248:7002 10.10.4.248:7003 10.10.4.248:7004 10.10.4.248:7005 10.10.4.248:7006
