使用docker-compose搭建Redis主从测试环境。
源码地址
编写docker-compose配置文件
version : '3'
networks:
network-redis:
driver: bridge
services:
master:
image: redis:5.0.5
container_name: redis5.0.6-master
networks:
- network-redis
ports:
- '6379:6379'
command: redis-server --requirepass redis_pwd --masterauth redis_pwd # 启动redis命令
slaves1:
image: redis:5.0.5
container_name: redis5.0.6-slaves1
networks:
- network-redis
ports:
- '6380:6379'
command: redis-server --slaveof redis5.0.6-master 6379 --requirepass redis_pwd --masterauth redis_pwd # 启动redis命令
slaves2:
image: redis:5.0.5
container_name: redis5.0.6-slaves2
networks:
- network-redis
ports:
- '6381:6379'
command: redis-server --slaveof redis5.0.6-master 6379 --requirepass redis_pwd --masterauth redis_pwd # 启动redis命令
- 指定密码redis_pwd 作为测试密码
启动测试
docker-compse -f docker-compose up -d
- Console
Starting redis5.0.6-master ... done
Starting redis5.0.6-slaves2 ... done
Starting redis5.0.6-slaves1 ... done
- 检查docker运行
docker ps
- 使用redis-cli检查
redis-cli
127.0.0.1:6379> auth redis_pwd
OK
127.0.0.1:6379> info replication

这里可以有两个slave。
可以使用客户端工具往master写入数据,看slave是否存在数据。
