redis - 获取 Redis 丢失的 Sentinel 错误消息

Question

我正在使用 spring data redis 运行 spring boot 服务，这里是以下配置。

该服务似乎可以正常工作，但我在日志中看到一连串 Lost Sentinel 消息。从我运行服务的 VM 可以访问哨兵节点。我能够直接从该虚拟机远程登录到他们。知道为什么会这样吗？

spring:
  profiles:
    active: core-perf,swagger
    default: core-perf,swagger
  redis:
    Pool:  #Pool properties
      # Max number of "idle" connections in the pool. Use a negative value to indicate
      # an unlimited number of idle connections.
      maxIdle: 8
      # Target for the minimum number of idle connections to maintain in the pool.
      # This setting only has an effect if it is positive.
      minIdle: 0
      # Max number of connections that can be allocated by the pool at a given time. Use a negative value for no limit.
      maxActive: 8
      # Maximum amount of time (in milliseconds) a connection allocation should block
      # before throwing an exception when the pool is exhausted. Use a negative value
      # to block indefinitely.

Answer 1

我们发现了这个问题。 application.yml 中的节点对之间有一个空白，一旦我们删除了这个“”，Lost Sentinel 日志消息就消失了。

所以从

nodes: 10.202.56.209:26379, 10.202.56.213:26379, 10.202.58.80:26379

到

nodes: 10.202.56.209:26379,10.202.56.213:26379,10.202.58.80:26379

如果提交者看到它可能是一件好事，因为它对用户来说似乎有些神秘。
