基础环境
操作系统版本 CentOS Linux release 7.6.1810 (Core)
Docker 版本 19.03.11, build 42e35e61f3
Redis 版本 3.2.3-alpine
网络配置使用docker macvlan ，创建命令如下：
docker network create -d macvlan --subnet=10.10.10.0/24 --gateway=10.10.10.1 -o parent=eth0 macnet
脚本内容如下：
参数解释：
cmd 定义redis容器启动命令
sentinel_cmd 定义sentinel容器启动命令
image 容器启动镜像
redis_conf redis容器配置文件
sentinel_conf sentinel容器配置文件
redis_quota redis容器cpu、内存配额
sentinel_quota sentinel容器cpu、内存配额
base_dir 脚本运行的家目录
base_conf_dir redis配置文件目录
envv 环境配置，为区分多套集群配置，暂时写死
