使用docker-compose部署Redis集群

一、部署三主三从的Redis集群

分别为6个节点建立挂载目录，每个目录下建立数据、配置、日志文件夹。

docker-compose内容如下：

version: '3'
services:
  redis1:
    image: redis:6.2.3
    restart: always
    ports:
      - "6379:6379"
      - "16379:16379"
    volumes:
      - "./6379/data:/data/redis"
      - "./6379/logs:/opt/redis/logs"
      - "./6379/etc/redis.conf:/etc/redis/redis.conf"
    command: redis-server /etc/redis/redis.conf
  redis2:
    image: redis:6.2.3
    restart: always
    ports:
      - "6380:6380"
      - "16380:16380"
    volumes:
      - "./6380/data:/data/redis"
      - "./6380/logs:/opt/redis/logs"
      - "/opt/redis/cluster/6380/etc/redis.conf:/etc/redis/redis.conf"
    command: redis-server /etc/redis/redis.conf
  redis3:
    image: redis:6.2.3
