我要评论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
