各redis的ip和端口如下：
主(redis-mater)：192.168.26.75:16379
从(redis-slaveof)：192.168.26.73:6380
三哨兵：(sentinel-26379)：192.168.73:26379
(sentinel-26380)：192.168.74:26380
(sentinel-26381)：192.168.75:26381
docker部署流程：
下载redis镜像
创建主data文件夹
1
| mkdir /home/yanwq/docker_data/redis/redis_data/data
|
docker运行主redis
1
| docker run --name redis-master --net=host -v /home/yanwq/docker_data/redis/redis_data1/data:/data -d redis:5.0.9 redis-server --port 16379
|
创建从data1文件夹
1
| mkdir /home/yanwq/docker_data/redis/redis_data1/data
|
docker运行从redis
1
| docker run --name redis-slaveof --net=host -v /home/yanwq/docker_data/redis/redis_data1/data:/data -d redis:5.0.9 redis-server --slaveof 192.168.26.75 16379 --port 6380
