2.0将压缩包内所有的配置文件放到/var/lib/docker/volumes/下
[root@xxx]# ll -h /var/lib/docker/volumes/| grep service_redis-700
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7001-conf
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7001-data
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7002-conf
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7002-data
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7003-conf
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7003-data
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7004-conf
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7004-data
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7005-conf
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7005-data
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7006-conf
drwxr-xr-x 3 root root 4.0K Jul 1 2019 service_redis-7006-data
3.0 首先创建一个Docker网卡
#创建swarm网络
docker network create -d overlay service_ov_net --attachable --subnet 172.169.0.0/16 --gateway
4.0 下载保存redis.yml 源配置

5.0 启动集群
docker-compose -f redis.yml up -d
6.0 进入redis容器中配置集群
这后面的命令也可以配置在redis.yml中,等配置写成所有的容器启动后去执行以下命令.
## 进入容器中（随意进入一个。这里是进入第一个）
docker exec -it service_redis-7001_1 /bin/bash
##执行构建集群命令
redis-cli --cluster create 172.168.7.12:7001 172.168.7.12:7002 172.168.7.12:7003 172.168.7.12:7004 172.168.7.12:7005 172.168.7.12:7006 --cluster-replicas 1
##查看集群
root@redis-7001:/data# redis-cli -p 7001

##redis集群三主三从分槽配置完成
$ 附带上自己docker环境下常用到的命令
####docker启动单个容器
docker start 容器名
####docker停止单个容器
docker stop 容器名
####停止删除所有容器
docker stop $(docker ps -a -q) && docker rm $(docker ps -a -q) -f
####删除所有镜像
docker image rm $(docker images -q) -f
####删除无用的卷
docker volume prune
####查看docker日志文件大小
ls -lh $(find /var/lib/docker/containers/ -name *-json.log)
####查找大文件
find / -type f -size +100M
####docker-compose方式创建启动容器
docker-compose -f zk.yml up -d
####docker-compose方式停止销毁容器
docker-compose -f zk.yml down
