################################# REPLICATION ################################# # Master-Slave replication. Use slaveof to make a Redis instance a copy of # another Redis server. A few things to understand ASAP about Redis replication. # # 1) Redis replication is asynchronous, but you can configure a master to # stop accepting writes if it appears to be not connected with at least # a given number of slaves. # 2) Redis slaves are able to perform a partial resynchronization with the # master if the replication link is lost for a relatively small amount of # time. You may want to configure the replication backlog size (see the next # sections of this file) with a sensible value depending on your needs. # 3) Replication is automatic and does not need user intervention. After a # network partition slaves automatically try to reconnect to masters # and resynchronize with them. # slaveof redis 6379 # redis是master的容器名 # If the master is password protected (using the "requirepass" configuration # directive below) it is possible to tell the slave to authenticate before # starting the replication synchronization process, otherwise the master will # refuse the slave request. # masterauth 123455 slave-read-only yes # slave只读
三个配置文件配置好后，就可以配置docker-composer.yml文件了
version: "3.7" networks: backend: driver: bridge services: ### Redis ################################################ # master redis: image: johnson19900110/redis:latest restart: always volumes: - ${DATA_PATH_HOST}/redis/master:/data - ./redis/config/redis-master.conf:/usr/local/etc/redis/redis.conf ports: - 6379:6379 networks: - backend # slave 1 redis-slave1: image: johnson19900110/redis:latest restart: always volumes: - ${DATA_PATH_HOST}/redis/slave1:/data - ./redis/config/redis-slave1.conf:/usr/local/etc/redis/redis.conf ports: - 6380:6379 networks: - backend depends_on: - redis # slave 2 redis-slave2: image: johnson19900110/redis:latest restart: always volumes: - ${DATA_PATH_HOST}/redis/slave2:/data - ./redis/config/redis-slave2.conf:/usr/local/etc/redis/redis.conf ports: - 6381:6379 networks: - backend depends_on: - redis - redis-slave1
然后就可以启动redis容器了
docker-composer up -d redis-slave2
这时候3个redis就已经启动起来了
这是我们进入master容器。在redis-cli命令下执行
