redis配置信息整理

redis部署分为几种方式：单机、哨兵（主从）、集群。对应这几种部署方式redis的配置信息也有不同，总结如下：

1. 单机模式：

spring:
  redis:
    database: 0
    timeout: 8000
    password: 123456
    host: 192.168.56.101
    port: 6379
    lettuce:
      pool:
        max-active: 16
        max-idle: 8
        max-wait: -1
        min-idle: 1

2. 哨兵模式：

spring:
  redis:
    database: 0
    timeout: 8000
    password: 123456
    sentinel:
      master: demo-master
      nodes:
        - 192.168.56.101:26379
        - 192.168.56.101:26380
        - 192.168.56.101:26381
    lettuce:
      pool:
        max-active: 16
        max-idle: 8
        max-wait: -1
        min-idle: 1

3. 集群模式：

spring:
  redis:
    database: 0
    timeout: 8000
    password: 123456
    cluster:
      nodes:
        - 192.168.56.101:7001
        - 192.168.56.101:7002
        - 192.168.56.101:7003
        - 192.168.56.101:7004
        - 192.168.56.101:7005
        - 192.168.56.101:7006
    lettuce:
      pool:
        max-active: 16
        max-idle: 8
        max-wait: -1
        min-idle: 1

上面这种配置是在springboot2.x下面，配置信息最终加载进配置类：org.springframework.boot.autoconfigure.data.redis.RedisProperties 。在springboot3.x以后，redis的所有配置信息在spring.data.redis下面，对应的配置内容要改为：

1. 单机模式：

spring:
  data:
    redis:
      database: 0
      timeout: 8000
      password: 123456
      host: 192.168.56.101
      port: 6379
      lettuce:
        pool:
          max-active: 16
          max-idle: 8
          max-wait: -1
          min-idle: 1

2. 哨兵模式：

spring:
  data:
    redis:
      database: 0
      timeout: 8000
      password: 123456
      sentinel:
        master: demo-master
        nodes:
          - 192.168.56.101:26379
          - 192.168.56.101:26380
          - 192.168.56.101:26381
      lettuce:
        pool:
          max-active: 16
          max-idle: 8
          max-wait: -1
          min-idle: 1

3. 集群模式：

spring:
  data:
    redis:
      database: 0
      timeout: 8000
      password: 123456
      cluster:
        nodes:
          - 192.168.56.101:7001
          - 192.168.56.101:7002
          - 192.168.56.101:7003
          - 192.168.56.101:7004
          - 192.168.56.101:7005
          - 192.168.56.101:7006
      lettuce:
        pool:
          max-active: 16
          max-idle: 8
          max-wait: -1
          min-idle: 1
