产品名：应用中心
产品想法：在手机上我们都有应用商店，应用商店收录了各种各样的app，当我们需要地图导航时只需要安装地图软件即可使用。在我们的开发与生产环境中，linux平台下安装软件需要有经验加持，才能避免各种坑。开发一款基于centos7的应用中心，在日常开发和生产环境中可以快捷方便的安装所需软件，并自动配置让软件相对运行到最优。
工具选择：ansible、nginx、python3、maraidb
ansible：使用jinja2的模板，使用ansible调度功能nginx：做代理并提供高并发访问python3：高扩展性可以将功能模块化maraidb：使用centos7自带的mysql数据库准备工作：
