YAML配置

1、单机部署/主从部署

spring:
  redis:
    database: 1
    host: 192.168.0.111
    password: 123456
    port: 6379
    timeout: 3000

2、哨兵部署

spring:
  redis:
    database: 1
    password: 123456
    port: 6379
    sentinel:
      master: mymaster
      nodes:
        - 192.168.0.111:26379
        - 192.168.0.112:26379
        - 192.168.0.113:26379
      password: 123456
    timeout: 10000ms

3、集群部署

spring:
  redis:
    password: 123456
    database: 1
    cluster:
      nodes:
        - 192.168.0.111:6379
        - 192.168.0.112:6379
        - 192.168.0.113:6379
    timeout: 3000ms
