摘要：    随着现代科技突飞猛进的发展，计算机网络也得到了大家的普及。目前全球互联网用户总量已经达到17亿左右，相比之下，全球的总人口数则为67亿。很显然，2020年以前会有更多的人投身到互联网中。据国家科学基金会(National Science Foundation)预测，2020年前全球互联网用户将增加到50亿。这样，互联网规模的进一步扩大将成为人们构建下一代互联网架构的主要考虑因素之一。24604
    基于LVNT的服务器架构优化可以帮助并解决这一问题。 无论是商业应用、科技需求还是用户，对于网络速度，功能应用，较多的服务器目前压力都比较大，再加上用户数量和需求数也进一步加大，以至于对请求进行并发处理能力、服务器的吞吐量、以及稳定性都是一大考验。因此构建高性能的网站变得尤为必要。虽然不断需要从服务器的性能上来提升服务器需求，也需要从构建服务器集群的角度来实现迫切需求的高性能、高可靠性、高性价比。使得利用率以及服务器性能得到较好的发挥。
    使用LVS（Linux Virtual Server）来使得整个服务能够提供一个较大的吞吐量，并使用Nginx、Varnish、Tomcat来实现各种服务。通过反向代理向后台请求，实现了动静结合，双管齐下。另外通过B/S模式，对整个服务器架构实现管理的作用，从而避免了由于对于linux操作系统不熟悉而不会使用的窘境。

Framework Optimization of Enterprises Website Server Based on LVNT
Abstract:  With the development of modern science and technology make a spurt of progress, the computer network has also been everyone's popularity. At present, the global Internet users total has reached about 17 billion, by contrast, the total number of the global population is 67 billion. Apparently, before 2020 there will be more people to join the internet. According to the National Science Foundation forecast, in 2020 before the global Internet users will increase to 50 billion. Thus, further expanded the scale of the Internet has become one of the main factors in people the construction of the next generation Internet architecture.
Optimization can help us solve the problem server architecture based on LVNT. Whether it is commercial applications, the demand of science and technology or the user, the network speed, function application, more server now pressure are very great, together with the number and the demand on the number of users has further increased, so that the user requests for concurrent processing capability, the server throughput, and stability is a big test. So the construction of the high performance website becomes necessary. Although we need to continue to improve server requirements from the server performance, also need to realize the urgent need of high performance, high reliability, high performance price ratio from the the construction of server cluster point. The utilization and the server has a high performance.
    We use LVS (Linux Virtual Server) to make the whole service can provide a larger throughput, and use Nginx, Varnish, Tomcat to achieve a variety of services. Agent to the background request through the reverse, the combination of static and dynamic, work along both lines. Moreover through the B/S mode, to realize the management function of the server architecture, which avoids not use dilemma unfamiliar to Linux operating system.
