Docker 搭建`redis`集群

此次搭建一个6节点的Redis集群，包括3个主节点和3个从节点。

安装目录 /usr/local/docker/redis-cluster 没有目录要新建此目录

cd /usr/local/docker/redis-cluster

一、编写`docker-compose.yml` 文件

vi docker-compose.yml

version: "3"
services:
  redis-master1:
    image: redis:5.0 # 基础镜像
    container_name: redis-master1 # 容器名称
    working_dir: /config # 切换工作目录
    environment: # 环境变量
      - PORT=6374 # 会使用config/nodes-${PORT}.conf这个配置文件
    ports: # 映射端口，对外提供服务
      - 6374:6374 # redis的服务端口
      - 16374:16374 # redis集群监控端口
    stdin_open: true # 标准输入打开
    tty: true # 后台运行不退出
    network_mode: host # 使用host模式
    privileged: true # 拥有容器内命令执行的权限
    volumes:
      - /usr/local/docker/redis-cluster/config:/config #配置文件目录映射到宿主机
    entrypoint: # 设置服务默认的启动程序
      - /bin/bash
      - redis.sh
  redis-master2:
    image: redis:5.0
    working_dir: /config
    container_name: redis-master2
    environment:
      - PORT=6375
    ports:
      - 6375:6375
      - 16375:16375
    stdin_open: true
    network_mode: host
    tty: true
    privileged: true
    volumes:
      - /usr/local/docker/redis-cluster/config:/config
    entrypoint:
      - /bin/bash
      - redis.sh
  redis-master3:
    image: redis:5.0
    container_name: redis-master3
    working_dir: /config
    environment:
      - PORT=6376
    ports:
      - 6376:6376
      - 16376:16376
    stdin_open: true
    network_mode: host
    tty: true
    privileged: true
    volumes:
      - /usr/local/docker/redis-cluster/config:/config
    entrypoint:
      - /bin/bash
      - redis.sh
  redis-slave1:
    image: redis:5.0
    container_name: redis-slave1
    working_dir: /config
    environment:
      - PORT=6377
    ports:
      - 6377:6377
      - 16377:16377
    stdin_open: true
    network_mode: host
    tty: true
    privileged: true
    volumes:
      - /usr/local/docker/redis-cluster/config:/config
    entrypoint:
      - /bin/bash
      - redis.sh
  redis-slave2:
    image: redis:5.0
    working_dir: /config
    container_name: redis-slave2
    environment:
      - PORT=6378
    ports:
      - 6378:6378
      - 16378:16378
    stdin_open: true
    network_mode: host
    tty: true
    privileged: true
    volumes:
      - /usr/local/docker/redis-cluster/config:/config
    entrypoint:
      - /bin/bash
      - redis.sh
  redis-slave3:
    image: redis:5.0
    container_name: redis-slave3
    working_dir: /config
    environment:
      - PORT=6379
    ports:
      - 6379:6379
      - 16379:16379
    stdin_open: true
    network_mode: host
    tty: true
    privileged: true
    volumes:
      - /usr/local/docker/redis-cluster/config:/config
    entrypoint:
      - /bin/bash
      - redis.sh

二、新建`config`目录，并配置好相关配置信息

mkdir config
进入config目录
cd config

三、配置`redis.sh` 配置信息

vi redis.sh

redis-server /config/nodes-${PORT}.conf

四、启动redis，并初始化集群配置

配置好后进入 /usr/local/docker/redis-cluster 目录，执行docker-compose up -d 启动，启动后进入redis容器,初始化redis集群配置

# 进入Redis容器
docker exec -it redis-master1 /bin/bash
# 初始化Redis集群命令
redis-cli --cluster create \
192.168.118.131:6374 192.168.118.131:6375 192.168.118.131:6376 \
192.168.118.131:6377 192.168.118.131:6378 192.168.118.131:6379 \
--cluster-replicas 1

集群创建过程中会让你确认配置，输入yes确认即可；

创建成功后我们可以使用redis-cli命令连接到其中一个Redis服务；

# 单机模式启动
redis-cli -h 127.0.0.1 -p 6374
# 集群模式启动
redis-cli -c -h 127.0.0.1 -p 6374

通过cluster nodes命令可以查看节点信息，发现符合3主3从的预期。

redis 的节点信息如下
