基于linuxnginx反向代理服務器的應用研究

1、I基于 Linux nginx 反向代理服務器的應用研究摘 要 隨著 Web 2.0 時代的到來，Web 服務器的訪問者數(shù)量快速增加。服務器的 CPU、I/O 處理能力很快成為企業(yè)業(yè)務增長的瓶頸，此時可以通過多臺服務器提供網(wǎng)絡服務解決問題。反向代理服務器，提供一個既可以提高系統(tǒng)性能又可以解決后期的動態(tài)擴展的方案。反向代理服務器是相對于正向代理服務器而言的，反向代理的對象是服務器集群。通過反向代理服務器實現(xiàn)多臺服務器協(xié)作提供不同的服務

2、，但對于客戶端表現(xiàn)為一臺服務器。本設計采用 nginx 實現(xiàn)，主要是利用 nginx 的高并發(fā)連接支持的特點，在中小型企業(yè)中是一個兼顧性能和成本的不錯選擇。本文主要研究了在 Linux 平臺下通過 nginx 的反向代理功能來實現(xiàn)負載均衡的方法。通過在后端搭建多臺 Web 服務器實現(xiàn)負載均衡，通過搭建MySQL 數(shù)據(jù)庫和 FTP 服務器實現(xiàn)動、靜態(tài)和靜態(tài)附件的分離。 關鍵字 Nginx，反向代理，負載均衡ABSTRACTWith th
