Redis master-slave replication

Redis Cluster

Functions:1. Master-slave backup to prevent host downtime; 2. Read-write separation, sharing the tasks of the master; 3. Task separation, such as sharing backup work and computing work separately from the server

Configuration:

Main Server

Make the Redis server accessible across the network

bind 0.0.0.0

Set requirepass (redis password)

Turn off protected-mode no

Configure slave

bind 0.0.0.0

Set requirepass (redis password)

Then let the slave do the work: such as RDB, open rdb and change dbfilename to a file ending with rdb

Set slaveof (if you are using a higher version of redis, replace slaveof with replicaof)

Here is the IP of the listening port master, that is, the port

Switch the slave to read-only mode (can not be changed)

Turn off protected-mode no
