【摘要】：随着互联网技术的不断发展,特别是电子商务的不断发展,网上购物的需求也在不断的增加。根据《2017-2022年中国电子商务市场运行态势及投资战略研究报告》中指出2015年中国电子商务市场交易额规模16.4万亿元,增长22.7%。而其中网络购物增长36.2%,成为推动电子商务市场发展的重要力量。面对如此大的机遇,电子商务网站运营商必须不断的提高网站的服务质量,虽然商品质量和价钱是顾客很关注的,但是用户在网上购物时的体验也是很重要的。当用户正在收索他想要的商品的信息时,输入收索关键字后点击页面“收索”按钮,页面必须在规定的一段时间内,显示出用户所要查询的商品的相关信息,否则用户将没有心情继续消费下去。据数据统计得出的结果,这个反应时间应该在5s以内。在用户选择完商品,添加到购物车以后,如果在付款阶段网络上付款排队的人比较多,则有可能会出现需要等待很长的时间或者可能付款失败这一系列的结果,如果用户没有耐心或者付款失败,可能他就不会继续购买该商品了,那么这就是该网站商城的一种损失。这从而也对Web服务器的性能提出越来越高的要求。本课题开题介绍了 Web的研究背景和国内外的研究现状,从而提出本课题研究的意义。在此基础上,介绍了web服务器的基本概念和web服务器的性能。然后介绍了图书商城系统,分析了该系统中运用的技术。通过业务分类来建立基于多类队列的数学模型,根据数学模型分析出该系统的瓶颈,发现缓存和多进程对于服务器性能的影响,从而提出优化方案。最终通过测试得出优化结果。本课题主要的工作有以下几点。研究图书商城系统的业务分类,并基于该分类提出了多类队列的数学模型,计算出该模型中定义的性能指标,根据这些指标分析出了图书商城系统的性能瓶颈;研究Apache服务器的缓存与多进程机制,提出了对于缓存与多进程的优化方案。该课题的研究是以web服务现有的环境为主,对现有的web服务器环境进行数学建模和有针对性的优化。这样网站运营商就会知道如何在现有的条件下,即在不加大运营网站的开资的情况下,最大化的提高网站的网络性能。提升用户的体验,从而就能取得较好的经济效益。
[Abstract]:With the continuous development of Internet technology, especially the continuous development of e-commerce. The demand for online shopping is also on the increase. According to the < 2017-2022 China e-commerce market operating situation and investment strategy research report, "2015 China e-commerce market transaction volume regulations." The mold is sixteen tillion three hundred and ninety-nine billion nine hundred and ninety-nine million nine hundred and ninety-nine thousand and nine hundred and ninety-nine yuan. The growth of 22.7. and the growth of online shopping 36.2, become an important force to promote the development of e-commerce market. Faced with such a great opportunity. E-commerce website operators must constantly improve the service quality of the site, although the quality of goods and prices are of great concern to customers. But the user's experience when shopping online is also important. When the user is collecting information about the product he wants, enter the search keyword and click the "receive" button on the page. The page must be in a specified period of time, showing the user to query the relevant information of the goods, otherwise, the user will not be in the mood to continue to consume. According to the results of statistics. This response time should be within 5 s. After the user selects the item and adds it to the shopping cart, there are more people waiting in line for payment on the payment stage network. There may be a series of results that require a long wait or that the payment may fail, and that if the user is impatient or fails to pay, he may not continue to buy the item. So this is a loss of the website mall. This also put forward higher and higher requirements for the performance of Web server. This topic introduces the background of Web research and domestic and foreign research status. On this basis, the basic concept of web server and the performance of web server are introduced. Then the book mall system is introduced. The technology used in the system is analyzed. The mathematical model based on multi-class queue is established by business classification. The bottleneck of the system is analyzed according to the mathematical model, and the influence of cache and multi-process on server performance is found. Finally, the optimization results are obtained by testing. The main work of this paper is as follows. The business classification of the book mall system is studied, and the mathematical model of multi-class queue is proposed based on the classification. The performance indexes defined in the model are calculated and the bottleneck of the system is analyzed according to these indexes. This paper studies the caching and multi-process mechanism of Apache server, and puts forward the optimization scheme of cache and multi-process. The research of this topic is based on the existing environment of web services. The existing web server environment for mathematical modeling and targeted optimization, so that website operators will know how to in the existing conditions, that is, in the case of not increasing the opening of operating websites. Maximize the network performance of the website and enhance the user's experience, so that better economic benefits can be achieved.
