摘要

针对公共自行车数据可视化系统的性能问题,提出了一种整合Web服务器集群、数据库集群以及缓存框架服务器的集群架构,设计并实现了基于该架构的公共自行车数据可视化系统。系统使用Nginx搭建反向代理服务器,使用Redis搭建缓存服务器。设计的系统还集成了Session一致性策略、前端性能优化等技术。针对公共自行车普通用户和管理者分别设计了移动端应用(APP)和Web可视化页面。测试结果表明:设计的系统满足了用户对公共自行车可视化系统功能和性能的要求。
        In order to enhance the performance of bike-sharing data visualization system,a cluster architecture which integrates web server cluster,database cluster and cache framework server is proposed,bike-sharing data visualization system based on this architecture is designed and realized. Nginx is used to set up reverse proxy server,Redis is used to set up cache service. Session consistency strategy and front-end performance optimization technology are also integrated in this system. A mobile terminal APP is designed for ordinary users,visualization Web pages are designed for bike-sharing managers. Test result shows that the system meets requirements of bikesharing visualization system properties and function for user.
