【正文】 畢業(yè)設(shè)計(jì)論文 1 摘 要 論文主要介紹了基于 ARM9的嵌入式 Web服務(wù)器 Boa的軟、硬件設(shè)計(jì)及其實(shí)現(xiàn)，其中硬件部分的核心是三星 的 S3C2410X為處理器。最后成果形式為可以遠(yuǎn)程訪問的 WebServer嵌入式服務(wù)器。 Boa是一款單任務(wù)的 HTTP服務(wù)器。與其他傳統(tǒng)的 Web服務(wù)器不同的是當(dāng)有連接請求到來時(shí) ,它并不為每個(gè)連接單獨(dú)創(chuàng)建進(jìn)程 , 也不通過復(fù)制自身進(jìn)程來處理多鏈接。而是通過建立 HTTP請求列表來處理多路 HTTP連接請求。同時(shí)它只為 CGI程序創(chuàng)建新的進(jìn)程 ,這樣就在最大程度上節(jié)省了系統(tǒng)資源 ,這對嵌入式系統(tǒng)來說至關(guān)重要。同時(shí)它 還具有自動(dòng)生成目錄、自動(dòng)解壓文件等功能。因此 , Boa在嵌入式系統(tǒng)中具有很高的應(yīng)用價(jià)值 。 關(guān)鍵詞 :ARM； Linux；嵌入式 Web 服務(wù)器； CGI 畢業(yè)設(shè)計(jì)論文 2 Abstract This paper has mainly developed the software hardware design and realization of the embedded Web server Boa based on ARM. And the core of the hardware part is S3C2410X microprocessor produced by Samsung . The final achievement is the embedded webserver which can remote visit. Boa is a singletasking HTTP server. That means that unlike traditional webservers, it does not fork for each ining connection, nor does it fork many copies of itself to handle multiple connections. It internally multiplexes all of the ongoing HTTP connections. And forks only for CGI programs, this is very important to embedded system. At the same time, it also has the function of automatic directory generation、 automatic file gunzipping and so on. So Boa is of highly value in the embedded system application. Keywords: ARM； Linux； Embedded Web server； CGI 畢業(yè)設(shè)計(jì)論文 3 目 錄 摘 要 ........................................................................................................................... 1 Abstract ......................................................................................................................... 2 目 錄 ......................................................................................................................... 3 第一章 引言 ................................................................................................................. 5 第二章 課題背景 ....................................................................................................... 6 嵌入式系統(tǒng)簡介 ............................................................................................................... 6 嵌入式系統(tǒng)和 Linux ........................................................................................................ 6 ARM9 硬件平臺(tái) ................................................................................................................ 7 ARM 簡介 ............................................. 7 JXARM92410 ARM 嵌入式教學(xué)實(shí)驗(yàn)系統(tǒng) ................... 8 第三章 嵌入式 Web 服務(wù)器 ........................................................................................ 9 概述 ................................................................................................................................... 9 Web 服務(wù)器原理 ................................................................................................................ 9 嵌入式 Web 服務(wù)器實(shí)現(xiàn)原理 .......................................................................................... 9 TCP/IP 協(xié)議 .......................................... 9 嵌入式 Web 服務(wù)器 Boa ................................................................................................ 10 Boa 概述 ............................................ 10 Boa 的功能實(shí)現(xiàn) ...................................... 11 第四章 CGI 技術(shù) ....................................................................................................... 12 CGI 概述 .......................................................................................................................... 12 CGI 工作原理 .................................................................................................................. 12 第五章 建立嵌入式系統(tǒng)開發(fā)環(huán)境 ........................................................................... 14 在 Vmware 下安裝 Redhat ....................................................................................... 14 編譯配置主機(jī)開發(fā)環(huán)境 ................................................................................................. 18 配置以太網(wǎng) .......................................... 18 安裝配置 tftp 服務(wù)器 ................................. 19 配置防火墻 .......................................... 21 配置 NFS 服務(wù)器 ...................................... 22 JXARM92410 中 Uboot 燒寫 ....................................................................................... 22 uboot 的功能 ....................................... 22 使用 ADT IDE 燒寫 uboot ............................. 23 第六章 系統(tǒng)功能的實(shí)現(xiàn) ........................................................................................... 25 GCC 簡介 ......................................................................................................................... 25 GCC 概述 ............................................ 25 GCC 基本用法 ........................................ 25 畢業(yè)設(shè)計(jì)論文 4 Linux 內(nèi)核移植 ............................................................................................................... 26 Linux 內(nèi)核源代碼的安裝 .............................. 26 Linux 交叉編譯環(huán)境的建立和使用 ...................... 27 Linux 內(nèi)核的配置和編譯 .............................. 27 加載 Linux 內(nèi)核映像 ..................................................................................................... 30 Boa Web 服務(wù)器的移植 .................................................................................................. 31 Boa Web 服務(wù)器的建立 ................................ 31 Linux 下動(dòng)態(tài) Web 頁面的實(shí)現(xiàn) ...................................................................................... 32 CGI 程序分析 ........................................ 32 Form 輸入的分析和解碼 ............................... 34 第七章 系統(tǒng)功能的測試 ........................................................................................... 36 測試 Web 服務(wù)器 ...........................................................................................................
