一、单例部署

1.下载镜像 

docker pull redis:5.0.8-buster

2.创建/usr/local/docker/nginx/docker-compose.yml文件 

version: '3.1'
services:
  redis:
    image: 'redis:5.0.8-buster'
    restart: always
    container_name: redis
    ports:
      - 6379:6379
    command: redis-server --requirepass "123456"

3.执行docker-compose.yml文件  

docker-compose up

4.访问redis

进入docker容器

docker exec -it redis bash

连接redis

redis-cli -h 127.0.0.1 -p 6379 -a 123456

set、get示例

127.0.0.1:6379> set hello world
OK
127.0.0.1:6379> get hello
"world"

二、主从部署 

1./redis/docker-compose.yml

version: '3.1'
services:
  redis-master:
    image: 'redis:5.0.8-buster'
    restart: always
    container_name: redis-master
    ports:
      - 6379:6379
    command: redis-server --requirepass "123456"
  redis-slave-1:
    image: 'redis:5.0.8-buster'
    container_name: redis-slave-1
    ports:
      - 6380:6379
    command: redis-server --slaveof redis-master 6379 --requirepass 123456 --masterauth 123456
  redis-slave-2:
    image: 'redis:5.0.8-buster'
    container_name: redis-slave-2
    ports:
      - 6381:6379
    command: redis-server --slaveof redis-master 6379 --requirepass 123456 --masterauth 123456

2./ sentinel/docker-compose.yml

version: '3.1'
services:
  sentinel-1:
    image: 'redis:5.0.8-buster'
    container_name: redis-sentinel-1
    ports:
      - 26379:26379
    command: redis-sentinel /usr/local/etc/redis/sentinel.conf
    volumes:
      - ./sentinel1.conf:/usr/local/etc/redis/sentinel.conf
  sentinel-2:
    image: 'redis:5.0.8-buster'
    container_name: redis-sentinel-2
    ports:
      - 26380:26379
    command: redis-sentinel /usr/local/etc/redis/sentinel.conf
    volumes:
      - ./sentinel2.conf:/usr/local/etc/redis/sentinel.conf
  sentinel-3:
    image: 'redis:5.0.8-buster'
    container_name: redis-sentinel-3
    ports:
      - 26381:26379
    command: redis-sentinel /usr/local/etc/redis/sentinel.conf
    volumes:
      - ./sentinel3.conf:/usr/local/etc/redis/sentinel.conf

3./sentinel/sentinel1.conf、/redis/sentinel2.conf、/redis/sentinel3.conf配置相同

port 26379
dir /tmp
sentinel monitor mymaster 127.0.0.1(主机ip地址) 6379(主机端口) 2(从机个数)
sentinel auth-pass mymaster 123456
sentinel down-after-milliseconds mymaster 30000
sentinel parallel-syncs mymaster 1
sentinel failover-timeout mymaster 180000
sentinel deny-scripts-reconfig yes

4.访问sentinel

redis-cli -h 127.0.0.1 -p 26379

查看配置信息

sentinel master mymaster
