1.创建安装目录

cd /mnt
mkdir redis-cluster
cd redis-cluster
mkdir -p 6380/conf 6381/conf 6382/conf

2.分别编写conf文件,在6380/conf 6381/conf 6382/conf下

1) 6380 redis.conf

port 6380
requirepass 123456
masterauth 123456
protected-mode no
daemonize no
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 15000
cluster-announce-ip 192.168.0.87
cluster-announce-port 6380
cluster-announce-bus-port 16380

2) 6381 redis.conf

port 6381
requirepass 123456
masterauth 123456
protected-mode no
daemonize no
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 15000
cluster-announce-ip 192.168.0.87
cluster-announce-port 6381
cluster-announce-bus-port 16381

3) 6382 redis.conf

port 6382
requirepass 123456
masterauth 123456
protected-mode no
daemonize no
appendonly yes
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 15000
cluster-announce-ip 192.168.0.87
cluster-announce-port 6382
cluster-announce-bus-port 16382

3.编写docker-compose.yml文件

version: "3.2"

# 定义服务，可以多个
services:
  redis-cluster:
    image: redis:6.0.8
    command: redis-cli -a 123456  --cluster create  192.168.0.87:6380 192.168.0.87:6381 192.168.0.87:6382 --cluster-replicas 0  --cluster-yes
    depends_on:
      - redis-6380
      - redis-6381
      - redis-6382
  redis-6380: # 服务名称
    image: redis:6.0.8 # 创建容器时所需的镜像
    container_name: redis-6380 # 容器名称
    restart: always # 容器总是重新启动
    ports:
      - 6380:6380
      - 16380:16380
    volumes: # 数据卷，目录挂载
      - ./etc_rc.local:/etc/rc.local
      - ./6380/conf/redis.conf:/etc/redis/redis.conf
      - ./6380/data:/data
    command: redis-server /etc/redis/redis.conf # 覆盖容器启动后默认执行的命令

  redis-6381:
    image: redis:6.0.8
    container_name: redis-6381
    restart: always
    ports:
      - 6381:6381
      - 16381:16381
    volumes:
      - ./etc_rc.local:/etc/rc.local
      - ./6381/conf/redis.conf:/etc/redis/redis.conf
      - ./6381/data:/data
    command: redis-server /etc/redis/redis.conf

  redis-6382:
    image: redis:6.0.8
    container_name: redis-6382
    restart: always
    ports:
      - 6382:6382
      - 16382:16382
    volumes:
      - ./etc_rc.local:/etc/rc.local
      - ./6382/conf/redis.conf:/etc/redis/redis.conf
      - ./6382/data:/data
    command: redis-server /etc/redis/redis.conf

4.完整目录结构

│  docker-compose.yml
│  
├─6380
│  └─conf
│          redis.conf
│          
├─6381
│  └─conf
│          redis.conf
│          
└─6382
    └─conf
            redis.conf

5.构建redis集群

docker-compose up -d

6.验证集群是否部署成功

docker exec -it redis-6381 bash
redis-cli -p 6381
auth 123456
cluster info
