docker 搭建 redis 集群（Redis-Cluster集群）

1、安装依赖项

yum install -y epel-release
yum install -y python-pip python-devel gcc
pip install --upgrade pip

2、安装 docker-compose

pin install docker-compose

容器初始化

使用docker-compose方式，先创建一个docker-compose.yml文件，内容如下：

version: ‘3‘

services:
 redis1:
  image: publicisworldwide/redis-cluster
  network_mode: host
  restart: always
  volumes:
   - /data/redis/8001/data:/data
  environment:
   - REDIS_PORT=8001

 redis2:
  image: publicisworldwide/redis-cluster
  network_mode: host
  restart: always
  volumes:
   - /data/redis/8002/data:/data
  environment:
   - REDIS_PORT=8002

 redis3:
  image: publicisworldwide/redis-cluster
  network_mode: host
  restart: always
  volumes:
   - /data/redis/8003/data:/data
  environment:
   - REDIS_PORT=8003

 redis4:
  image: publicisworldwide/redis-cluster
  network_mode: host
  restart: always
  volumes:
   - /data/redis/8004/data:/data
  environment:
   - REDIS_PORT=8004

 redis5:
  image: publicisworldwide/redis-cluster
  network_mode: host
  restart: always
  volumes:
   - /data/redis/8005/data:/data
  environment:
   - REDIS_PORT=8005

 redis6:
  image: publicisworldwide/redis-cluster
  network_mode: host
  restart: always
  volumes:
   - /data/redis/8006/data:/data
  environment:
   - REDIS_PORT=8006

3、启动redis集群

docker-compose up -d

4、查看已经启动的进程

docker-compose ps

5、初始化集群

如果在这里要重新初始化，可以 docker-compose up stop 后，删除 volumes 配置的对应数据目录，然后 docker-compose up -d 重新启动，然后初始化

docker run --rm -it inem0o/redis-trib create --replicas 1 172.19.165.222:8001 172.19.165.222:8002 172.19.165.222:8003 172.19.165.222:8004 172.19.165.222:8005 172.19.165.222:8006

接下来就可以使用 Redis Desktop Manager 等工具连接了，记得要取消勾选 change host on cluster redirects:
