redis 哨兵 原理
English:
Redis Sentinel, also known as Redis Sentinel, is a distributed system
designed to monitor and manage the state of Redis servers. The
Sentinel consists of multiple processes that are responsible for
monitoring the master and slave instances of the Redis server. The
main principle of Redis Sentinel is to promote high availability and
failover in the Redis environment. It achieves this by constantly
monitoring the health of the Redis servers through regular heartbeat
messages and responding to server failures by initiating a failover
process. When a master Redis server is detected as unavailable, the
Sentinel will select a new master from the available Redis slaves and
redirect the client requests to the newly elected master. This allows
Redis to continue functioning with minimal interruption, ensuring
high availability and fault tolerance.

Redis Sentinel，也称为Redis Sentinel，是一个分布式系统，旨在监视和
管理Redis服务器的状态。Sentinel由多个进程组成，负责监视Redis服
务器的主服务器和从服务器实例。Redis Sentinel的主要原则是在Redis环
境中促进高可用性和故障转移。它通过定期的心跳消息不断监视Redis服务
器的健康状况，并在服务器故障时通过启动故障转移过程来进行响应。当检
测到主Redis服务器不可用时，Sentinel将从可用的Redis从服务器中选
择新的主服务器，并将客户端请求重定向到新选举的主服务器。这使得
Redis能够在最小中断的情况下继续运行，确保高可用性和容错性。
