节目互动网站升级改造的设计与实现
发布时间：2018-10-17 17:15
【摘要】：本文来源于本人参与的一个电视台的节目互动网站的升级改造。该节目互动网站为电视台的栏目开设互动版块，提供节目视频点播、内容分享、观众互动等服务。由于用户访问量的持续上升，原有系统已经没法满足用户日益增长的访问需求，需要对系统进行升级改造。 本次升级改造的目标是把节目互动网站打造成一个高性能、高可靠性、易扩展的网站。在网站改造过程中，通过负载均衡策略扩展网站系统的规模，提高网站的性能与可靠性；通过缓存策略包括浏览器缓存、反向代理缓存、数据库数据缓存等，减轻核心服务器的负载，提高网站系统的响应速度；通过数据库读写分离、主从同步策略，组建数据库集群，，提升数据库的整体性能与可靠性；通过外挂存储的方式，大幅扩展系统的存储空间。系统关键部分采用备份、冗余措施，消除网络单点故障，提升系统的容错和恢复能力，提高网站的可靠性。 升级改造后的网站，有助于电视台品牌栏目向网络延伸，充分满足观众不断提高的节目互动需求，对于增强电视台在三网融合中的行业竞争力，扩大电视台的品牌影响力具有十分重要的意义。
[Abstract]:This article comes from the upgrade of a TV station's interactive website. The interactive program website provides interactive sections for TV programs, video on demand, content sharing, audience interaction, and so on. Due to the continuous increase in the number of users, the original system can not meet the increasing demand of users, so it is necessary to upgrade the system. The goal of this upgrade is to create a high-performance, high-reliability, easy-to-extend website. In the process of website transformation, the scale of the website system is expanded by load balancing strategy, and the performance and reliability of the website are improved, including browser cache, reverse proxy cache, database data cache and so on. Lighten the load of the core server, improve the response speed of the website system; through database read-write separation, master-slave synchronization strategy, set up a database cluster, improve the overall performance and reliability of the database; through external storage, Greatly extend the storage space of the system. The key part of the system adopts backup and redundancy measures to eliminate the single point fault of the network, improve the fault tolerance and recovery ability of the system, and improve the reliability of the website. After upgrading the website, it is helpful for TV brand columns to extend to the network, to fully meet the increasing interactive needs of the audience, and to enhance the industry competitiveness of TV stations in the process of integration of the three networks. It is of great significance to expand the brand influence of TV stations.
