1.创建6个文件夹

2.创建docker-compose.yml

services:
  redis16379:
    image: redis
    container_name: redis16379
    restart: always
    privileged: true
    network_mode: "host"
    volumes:
      - ./redis16379/data:/data
      - ./redis16379/redis.conf:/etc/redis.conf
    command:
      redis-server /etc/redis.conf

  redis16479:
    image: redis
    container_name: redis16479
    restart: always
    privileged: true
    network_mode: "host"
    volumes:
      - ./redis16479/data:/data
      - ./redis16479/redis.conf:/etc/redis.conf
    command:
      redis-server /etc/redis.conf

  redis16579:
    image: redis
    container_name: redis16579
    restart: always
    privileged: true
    network_mode: "host"
    volumes:
      - ./redis16579/data:/data
      - ./redis16579/redis.conf:/etc/redis.conf
    command:
      redis-server /etc/redis.conf

  redis17379:
    image: redis
    container_name: redis17379
    restart: always
    privileged: true
    network_mode: "host"
    volumes:
      - ./redis17379/data:/data
      - ./redis17379/redis.conf:/etc/redis.conf
    command:
      redis-server /etc/redis.conf

  redis17479:
    image: redis
    container_name: redis17479
    restart: always
    privileged: true
    network_mode: "host"
    volumes:
      - ./redis17479/data:/data
      - ./redis17479/redis.conf:/etc/redis.conf
    command:
      redis-server /etc/redis.conf

  redis17579:
    image: redis
    container_name: redis17579
    restart: always
    privileged: true
    network_mode: "host"
    volumes:
      - ./redis17579/data:/data
      - ./redis17579/redis.conf:/etc/redis.conf
    command:
      redis-server /etc/redis.conf

3. 在每个redis目录下创建redis.conf

一共六个配置只需修改端口号其余内容一致

[ka@localhost redis16379]$ vi redis.conf

protected-mode no

bind 0.0.0.0

save 900 1
save 300 10
save 60 10000

rdbcompression yes

dbfilename dump.rdb

dir /data

# 日志存放位置
logfile /data/redis.log

# 开启集群功能
cluster-enabled yes

# 集群的配置文件名称，不需要我们创建，由redis自己维护
cluster-config-file /tmp/nodes.conf

# 节点心跳失败的超时时间
cluster-node-timeout 5000

# 关闭 aof 日志备份
appendonly no

# 启动端口
port 16379

# 自定义密码
#requirepass root

# 访问 master 节点时需要提供的密码
#masterauth root

# 虚拟机会有多个 ip，这里指定具体一个 ip 地址
replica-announce-ip 192.168.56.10

4.启动创建容器

docker-compose up -d

5.创建集群

进入一个容器

docker exec -it redis16379  bash

执行命令

redis-cli --cluster create 192.168.56.10:16379 192.168.56.10:16479 192.168.56.10:16579
192.168.56.10:17379 192.168.56.10:17479 192.168.56.10:17579 --cluster-replicas 1
