Because the master failover decision is based on a quorum system, at least three Sentinel processes are required as a robust distributed system that keeps monitoring the status of the Redis master data server. If multiple Sentinel processes detect that the master is down, one of the Sentinel process will be elected to promote a slave to replace the old master. With proper configuration, the entire process is automatic without any human intervention. In this recipe, we will demonstrate how to set up a simple environment of one master and two slaves, which is monitored by three Sentinels.
