Redis Sentinel is a distributed monitoring, high availability, and failure detection solution for Redis data stores. It is designed to manage multiple Redis instances by providing automatic failover, notifications, and configuration support.
To use Redis Sentinel, you will need to create a sentinel configuration file (e.g.,
sentinel.conf) containing the required settings.
# Set the monitored Redis master instance sentinel monitor mymaster 127.0.0.1 6379 2 # Set the quorum for the number of sentinels required to agree before starting a failover process sentinel down-after-milliseconds mymaster 5000 # Set the time after which a replica not responding will be considered down sentinel failover-timeout mymaster 10000 # Add authentication if necessary sentinel auth-pass mymaster your_password_here
To launch Redis Sentinel, run the following command:
Now, Redis Sentinel will monitor the specified Redis instances and handle failover as needed.
Dragonfly is fully compatible with the Redis ecosystem and requires no code changes to implement.
