A brief introduction to the following redis-sentinel:
Redis-sentinel is the management tool for Redis clusters, which is the monitoring management, notification and instance failover service for Redis instances. In the general distributed central
Redis does not generate a log file by default, so it needs to be configured
Configuration method:
1. First find the Redis configuration file
2, open the configuration file, find logfile (there may be multiple logfile, look for the next loglevel)
