基于 Linux nginx 反向代理服务器的应用讨论摘 要 随着 Web 2.0 时代的到来，Web 服务器的访问者数量快速增加。服务器的 CPU、I/O 处理能力很快成为企业业务增长的瓶颈，此时可以通过多台服务器提供网络服务解决问题。反向代理服务器，提供一个既可以提高系统性能又可以解决后期的动态扩展的方案。反向代理服务器是相对于正向代理服务器而言的，反向代理的对象是服务器集群。通过反向代理服务器实现多台服务器协作提供不同的服务，但对于客户端表现为一台服务器。本设计采纳 nginx 实现，主要是利用 nginx 的高并发连接支持的特点，在中小型企业中是一个兼顾性能和成本的不错选择。本文主要讨论了在 Linux 平台下通过 nginx 的反向代理功能来实现负载均衡的方法。通过在后端搭建多台 Web 服务器实现负载均衡，通过搭建MySQL 数据库和 FTP 服务器实现动、静态和静态附件的分离。 关键字 Nginx，反向代理，负载均衡ABSTRACTWith the arrival of the era of Web 2.0,the number of visitors of the Web server increases rapidly.Server CPU and I/O processing power soon becomes the bottleneck of enterprise business growth,now we can solve the problem through network services which offered by multiple servers.Reverse proxy server,providing a plan which can improve system performance and solve dynamic expansion for later.Reverse proxy server is relative to the proxy server,reverse proxy object is a server cluster.Through reverse proxy server realize multiple servers provides different services,but for client it acts as one server.This design uses the nginx to realize, mainly using its characteristic of high concurrent connections ,it is a good choice for small and medium-sized enterprises between performance and cost .This paper mainly studied in the method of using nginx reverse proxy function to achieve load balancing on Linux platform.Through building multiple Web servers backend realize load balancing,through constructing the MySQL database and FTP server realize sta...
