基于linuxnginx反向代理服務(wù)器的應(yīng)用研究

1、I基于 Linux nginx 反向代理服務(wù)器的應(yīng)用研究摘 要 隨著 Web 2.0 時(shí)代的到來，Web 服務(wù)器的訪問者數(shù)量快速增加。服務(wù)器的 CPU、I/O 處理能力很快成為企業(yè)業(yè)務(wù)增長的瓶頸，此時(shí)可以通過多臺(tái)服務(wù)器提供網(wǎng)絡(luò)服務(wù)解決問題。反向代理服務(wù)器，提供一個(gè)既可以提高系統(tǒng)性能又可以解決后期的動(dòng)態(tài)擴(kuò)展的方案。反向代理服務(wù)器是相對(duì)于正向代理服務(wù)器而言的，反向代理的對(duì)象是服務(wù)器集群。通過反向代理服務(wù)器實(shí)現(xiàn)多臺(tái)服務(wù)器協(xié)作提供不同的服務(wù)

2、，但對(duì)于客戶端表現(xiàn)為一臺(tái)服務(wù)器。本設(shè)計(jì)采用 nginx 實(shí)現(xiàn)，主要是利用 nginx 的高并發(fā)連接支持的特點(diǎn)，在中小型企業(yè)中是一個(gè)兼顧性能和成本的不錯(cuò)選擇。本文主要研究了在 Linux 平臺(tái)下通過 nginx 的反向代理功能來實(shí)現(xiàn)負(fù)載均衡的方法。通過在后端搭建多臺(tái) Web 服務(wù)器實(shí)現(xiàn)負(fù)載均衡，通過搭建MySQL 數(shù)據(jù)庫和 FTP 服務(wù)器實(shí)現(xiàn)動(dòng)、靜態(tài)和靜態(tài)附件的分離。 關(guān)鍵字 Nginx，反向代理，負(fù)載均衡ABSTRACTWith th
