基于分布式文件系统的教学云平台设计与实现

Design and implementation of teaching cloud platform based on distributed file system

为解决高校传统教学平台操作复杂、使用流程繁琐的问题,文章提出并实现了一个更人性化且易于对存储系统进行水平扩展的一体化教学云平台。存储技术采用BFS百度文件系统,数据库管理系统融合MySQL及Redis各自的优势,Web前后端采用Symfony框架,并结合WebUploder实现文件传输功能。该软件可在高吞吐情况下保证低延迟和持续可用性,并较大提升了用户友好性。

In order to solve the problems of complex operation and cumbersome use process of traditional teaching platform in colleges and universities, improving user experience, this paper analyzed the shortcomings of the overall framework of the existing teaching platform in the university, and proposed and implemented an integrated teaching cloud platform solution that is more user-friendly as well as easier to horizontally expand the storage system. This scheme adopts the mainstream PHP MVC framework Symfony, combining with Web Uploder file upload component, using hybrid database system that integrates the advantages of MySQL and Redis, and adopts Baidu distributed file system, which can guarantee low latency and continuous availability in the case of high throughput. Based on this, we implemented a teaching cloud platform with better UI experience and support for concurrent upload of large files.
