A Redis cluster is an installation where data can be shared among multiple Redis nodes.

Redis clusters do not support Redis commands that require multiple keys to be processed simultaneously, because executing these commands requires moving data between multiple Redis nodes, and under high load, these commands will degrade the performance of the Redis cluster and cause unpredictable errors.

Redis nodes in redis cluster are interconnected (PING-PONG mechanism). Binary protocol is used internally to optimize transmission speed and bandwidth. There is no host. Clients can connect to any node at will.

Normal shutdown redis

Execute shutdown directly on the client or redis-cli -p 7001 shutdown directly on the command line

Let's just write shutdown.sh

Or directly kill -9 ${process number}(if you want to kill multiple processes at once, then space between process numbers can be separated)

Related instructions:

#View redis process ps -ef| grep redis# kill process kill -9 2177 2217

If the cluster has been built before, and all nodes are killed for some reason, if you need to start the cluster at this time, you only need to start each Redis node one by one, and the cluster will naturally rise.

Related instructions:

#background launch Redissrc/redis-server redis.conf

The above is the details of how to close redis Cluster, please pay more attention to other related articles!
