redis主从架构的搭建及添加哨兵

单机版主从架构读写操作问题

主从架构搭建步骤

1，在opt目录下创建一个docker_redis_master_salve文件夹，并创建docker-compose.yml文件，输入配置内容

2，在docker_redis_master_salve文件夹下创建一个conf文件夹

3，在conf文件夹下分别创建redis1.conf，redis2.conf，redis3.conf文件

4，在redis2.conf，redis3.conf文件在分别配置replicaof 192.168.206.140 6379来连接上master主机，并设置相应的端口

5，docker-compose up -d启动容器，如果出现UnixHTTPConnectionPool(host=‘localhost’, port=None): Read timed out. (read timeout=60)的错误，则需要在/etc/profile配置文件中添加如下配置：

export DOCKER_CLIENT_TIMEOUT=120

export COMPOSE_HTTP_TIMEOUT=120

6，通过docker-compose logs -f 查看日志，没问题后进行测试

7，在master主机进行set和get操作，测试是否成功

8，在slave从机测试是否可以获取主机set的数据，再测试slave从机set数据

version: "3.1"
services:
  redis1:
    image: daocloud.io/library/redis:5.0.7
    restart: always
    container_name: redis1
    environment:
      - TZ=Asia/Shanghai
    network_mode: host
    volumes:
      - ./conf/redis1.conf:/usr/local/redis/redis.conf
    command: ["redis-server","/usr/local/redis/redis.conf"]
  redis2:
    image: daocloud.io/library/redis:5.0.7
    restart: always
    container_name: redis2
    environment:
      - TZ=Asia/Shanghai
    network_mode: host
    volumes:
      - ./conf/redis2.conf:/usr/local/redis/redis.conf
    command: ["redis-server","/usr/local/redis/redis.conf"]
  redis3:
    image: daocloud.io/library/redis:5.0.7
    restart: always
    container_name: redis3
    environment:
      - TZ=Asia/Shanghai
    network_mode: host
    volumes:
      - ./conf/redis3.conf:/usr/local/redis/redis.conf
    command: ["redis-server","/usr/local/redis/redis.conf"]
    

redis1主节点的配置

port 6379

redis2从节点配置

replicaof 10.10.10.10  6379
port 6380

redis3从节点配置

replicaof 10.10.10.10   6379
port 6381

加入哨兵机制
哨兵可以帮助我们解决主从架构中的单点故障问题

每个redis块中多加入了一个数据
卷 - ./conf/sentinel.conf:/data/sentinel.conf

version: "3.1"
services:
  redis1:
    image: daocloud.io/library/redis:5.0.7
    restart: always
    container_name: redis1
    environment:
      - TZ=Asia/Shanghai
    network_mode: host
    volumes:
      - ./conf/redis1.conf:/usr/local/redis/redis.conf
      - ./conf/sentinel1.conf:/data/sentinel.conf
    command: ["redis-server","/usr/local/redis/redis.conf"]
  redis2:
    image: daocloud.io/library/redis:5.0.7
    restart: always
    container_name: redis2
    environment:
      - TZ=Asia/Shanghai
    network_mode: host
    volumes:
      - ./conf/redis2.conf:/usr/local/redis/redis.conf
      - ./conf/sentinel2.conf:/data/sentinel.conf
    command: ["redis-server","/usr/local/redis/redis.conf"]
  redis3:
    image: daocloud.io/library/redis:5.0.7
    restart: always
    container_name: redis3
    environment:
      - TZ=Asia/Shanghai
    network_mode: host
    volumes:
      - ./conf/redis3.conf:/usr/local/redis/redis.conf
      - ./conf/sentinel3.conf:/data/sentinel.conf
    command: ["redis-server","/usr/local/redis/redis.conf"]

redis1主节点的配置

port 6379

redis2从节点配置

replicaof 10.10.10.10  6379
port 6380

redis3从节点配置

replicaof 10.10.10.10  6379
port 6381

准备哨兵的配置文件，并且在容器内部手动启动哨兵即可
每个配置文件不同，只需要修改ip地址，和指定哨兵的端口号

哨兵需要后台启动cd

daemonize yes

指定Master节点的ip和端口（主）,从机台数

sentinel monitor master 10.10.10.10 6379 2

指定哨兵的端口号

port 26379

哨兵每隔多久监听一次redis架构

sentinel down-after-milliseconds master 10000

在Redis容器内部启动sentinel
redis-sentinel在/usr/local/bin中

redis-sentinel sentinel.conf
