Web2.0的兴起，掀起了互联网新一轮的网络创业大潮。以用户为导向的新网站建设概念，细分了网站功能和用户群，不仅成功的造就了一大批新生的网站，也极大的方便了上网的人们。但Web2.0以用户为导向的理念，使得新生的网站有了新的特点——高并发，高流量，数据量大，逻辑复杂等，对网站建设也提出了新的要求。 本文围绕高并发高流量的网站架构设计问题，主要研究讨论了以下内容:首先在整个网络的高度讨论了使用镜像网站，CDN内容分发网络等技术对负载均衡带来的便利及各自的优缺点比较。然后在局域网层次对第四层交换技术，包括硬件解决方案F5和软件解决方案LVS，进行了简单的讨论。接下来在单服务器层次，本文着重讨论了单台服务器的Socket优化，硬盘级缓存技术，内存级缓存技术，CPU与10平衡技术(即以运算为主的程序与以数据读写为主的程序搭配部署)，读写分离技术等。在应用层，本文介绍了一些大型网站常用的技术，以及选择使用该技术的理由。最后，在架构的高度讨论了网站扩容，容错等问题。 本文以理论与实践相结合的形式，结合作者实际工作中得到的经验，具有较广泛的适用性。

With web2.0 starting， raised the Internet new turn of network to start undertaking the flood tide. To be user-oriented concept of the new websites, not only successfully created a large number of new sites, but also greatly facilitate the development of the Internet people. The Web2.0 at the same time take the user as the guidance idea, enabled the newborn website to have the new characteristic - high concurrency, high page views, big data quantity, and complex logic , etc., also set the new request to the website construction. This article revolves the high concurrent high current capacity the website overhead construction design question, the main research discussed these content: First discussed the useage of mirror sites in the entire network, CDN content distribution network, the convenience and respective good and bad points comparison which brings to the load balancing. Then in the local area network, the fourth level exchange technology, including hardware solution F5 and software solution LVS, has been carried on with a simple discussion. Received in the single server level, this article emphatically discussed the single server socket optimization, the hard disk cache technology, the memory level buffer technology,CPU and the IO balance technology, the read-write separation technology and so on.In the application level, this article introduced some large-scale website commonly used technologies, as well as the reason of choice of these technicals. Finally, highly discussed the website in the overhead construction to expand accommodates,fault-tolerant. This article form which unifies by the theory and the practice,experience which in the author practical work obtains, has amore widespread serviceability.
