- 准备目录
mkdir rs01/data
mkdir rs02/data
mkdir rs03/data
mkdir rs04/data
mkdir rs05/data
mkdir rs06/data
准备端口配置
rs01: 6379
rs02: 6380
rs03: 6381
rs04: 6382
rs05: 6383
rs06: 6384准备redis.conf , 例如 rs01的. 192.168.1.8 为宿主机器的ip，因在一台机器上，所以设置一样即可。根据实际情况配置
# 服务的对外访问端口
port 6379
# 访问密码
requirepass 123456
# 集群中节点连接时，密码
masterauth 123456
appendonly yes
# 将bind注释掉，不然后面执行会报 节点不是cluster的错误
# [ERR] Node 192.168.1.105:7003 is not configured as a cluster node.
#bind 127.0.0.1 -::1
# 开启集群功能
cluster-enabled yes
# 集群配置文件
cluster-config-file nodes.conf
# 节点心跳失败的超时时间
cluster-node-timeout 5000
# 集群对外访问ip.port
cluster-announce-ip 192.168.1.8
cluster-announce-port 6379
# 集群内部通信接口
cluster-announce-bus-port 16379
# 持久化目录存放位置
dir ./
# 绑定地址
bind 0.0.0.0
# 主从实例的IP地址
replica-announce-ip 192.168.1.8
# 保护模式,关闭则不会校验用户名密码的校验
protected-mode no
# redis后端运行,当为yes时，看不到日志，可以配置日志的输入文件
#daemonize yes
# 日志文件
#logfile /tmp/redis/run.log
- 准备docker-compose.yml

services:
redis-cluster:
image: redis:latest
# --cluster-replicas 1 表明每一个master会有一个从节点，形成了1个master:1个对应的从节点
# 无需从节点： --cluster-replicas 0， 即全部为主节点

- 查看集群信息, 可以看到每一个后面都会有1 slaves,说明都有一个从节点
PS D:\docker\redis\redis-cluster> docker exec -it redis-1 redis-cli --cluster info 192.168.1.8:6379 -a 123456

- 测试主从切换 可以看到主节点 redis-2，则其从节点会升级到主节点，因没有其他节点可成为从节点，则会显示0 slaves
PS D:\docker\redis\redis-cluster> docker stop redis-2
