摘要论文主要介绍了基于ARM9的嵌入式Web服务器Boa的软、硬件设计及其实现，其中硬件部分的核心是三星的S3C2410X为处理器。
最后成果形式为可以远程访问的WebServer嵌入式服务器。
Boa是一款单任务的HTTP服务器。
与其他传统的Web服务器不同的是当有连接请求到来时,它并不为每个连接单独创建进程, 也不通过复制自身进程来处理多链接。
而是通过建立HTTP请求列表来处理多路HTTP连接请求。
同时它只为CGI程序创建新的进程,这样就在最大程度上节省了系统资源,这对嵌入式系统来说至关重要。
同时它还具有自动生成目录、自动解压文件等功能。
因此, Boa在嵌入式系统中具有很高的应用价值。
关键词:ARM；Linux；嵌入式Web服务器；CGIThis 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 single-tasking HTTP server. That means that unlike traditional webservers, it does not fork for each incoming 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摘要 (1)Abstract (2)目录 (3)第一章引言 (5)第二章课题背景 (6)2.1 嵌入式系统简介 (6)2.2 嵌入式系统和Linux (6)2.3 ARM9硬件平台 (7)2.3.1 ARM简介 (7)2.3.2 JXARM9-2410 ARM嵌入式教学实验系统 (8)第三章嵌入式Web服务器 (9)3.1 概述 (9)3.2 Web服务器原理 (9)3.3 嵌入式Web服务器实现原理 (9)3.3.1 TCP/IP协议 (9)3.4 嵌入式Web服务器Boa (10)3.4.1 Boa概述 (10)3.4.2 Boa的功能实现 (11)第四章CGI技术 (12)4.1 CGI概述 (12)4.2 CGI工作原理 (12)第五章建立嵌入式系统开发环境 (14)5.1 在Vmware下安装Redhat 9.0 (14)5.2 编译配置主机开发环境 (18)5.2.1 配置以太网 (18)5.2.2 安装配置tftp服务器 (19)5.2.3 配置防火墙 (21)5.2.4 配置NFS服务器 (22)5.3 JXARM9-2410中U-boot烧写 (22)5.3.1 u-boot的功能 (22)5.3.2 使用ADT IDE烧写u-boot (23)第六章系统功能的实现 (25)6.1 GCC简介 (25)6.1.1 GCC概述 (25)6.1.2 GCC基本用法 (25)6.2 Linux内核移植 (26)6.2.1 Linux内核源代码的安装 (26)6.2.2 Linux交叉编译环境的建立和使用 (27)6.2.3 Linux内核的配置和编译 (27)6.3 加载Linux内核映像 (30)6.4 Boa Web服务器的移植 (31)6.4.1 Boa Web服务器的建立 (31)6.5 Linux下动态Web页面的实现 (32)6.5.1 CGI程序分析 (32)6.5.2 Form输入的分析和解码 (34)第七章系统功能的测试 (36)7.1 测试Web服务器 (36)7.2 动态Web页面测试 (37)结束语 (40)致谢 (41)参考文献 (42)附录 (43)第一章引言随着计算机技术的发展，嵌入式系统已成为计算机领域的一格重要组成部分。

This paper designs an embedded device Web server based on LwIP protocol. The internal parameters of embedded devices can be configured and updated by using the web page. The Web server make full use of the platform of STM32 internal integration Ethernet modules and the characteristics of LwIP light network protocol stack. Through the Ethernet physical layer chip LAN8720 and RJ45 interface to link together,Web pages and Web server can achieve bidirectional data transmission. The test shows that the embedded device Web server based on the LwIP protocol stack is correct and feasible.【期刊名称】《电子设计工程》【年(卷),期】2018(026)011【总页数】4页(P110-113)【关键词】LwIP;STM32;LAN8720;Web服务器;嵌入式设备【作者】陈志星;杨金孝【作者单位】西北工业大学电子信息学院,陕西西安710129;西北工业大学电子信息学院,陕西西安710129【正文语种】中文【中图分类】TN919.6随着物联网技术的兴起和智能家居的发展，嵌入式设备需要接入局域网或者因特网已成为一种趋势，由于网口通信比其他模式通信速率高且抗干扰性强，在局域网中往往很多嵌入式设备只留有网口供于外部通信，此时对于嵌入式设备内部一些参数设置和内部程序升级只能由网口通信完成。
嵌入式系统的设计和实现嵌入式系统是指集成了计算机芯片、控制器、传感器等硬件设备的特殊电子设备系统。
它通常运行在一些资源受限的嵌入式处理器上，具有实时性、可靠性、成本低廉等特点。
如今，随着信息技术的迅速发展，嵌入式系统已经广泛应用在各种领域，例如智能家居、智能交通、智能医疗等。
嵌入式系统设计开发的核心，在于硬件电路的设计和程序代码的编写。
本文将从嵌入式系统的设计和实现两个方面，探讨如何开发一款成功的嵌入式系统。
一、嵌入式系统的设计1.硬件电路设计嵌入式系统的硬件设计是系统整体性能的基础，是开发过程中必不可少的一步。
在设计硬件电路时，需要首先了解嵌入式系统所需的硬件组件，比如处理器、存储器、输入输出设备、传感器等。
其次，需要根据设计目标和系统要求，选择合适的硬件设备，并将其组合成合理的电路结构。
最后，需要完成电路设计的的绘制及原理图、PCB的布线等工作。
在这个过程中，设计者需要考虑功耗、散热、成本等多个因素。
2.软件设计嵌入式系统的软件设计是嵌入式系统开发的重中之重。
在软件设计方面，需要仔细考虑嵌入式系统的程序架构及程序设计模式，比如事件驱动模型或多任务模型。
同时，需要考虑系统的实时性和稳定性，确保系统代码的质量和可靠性。
在软件设计过程中，需要使用一些工具和开发环境，如Keil、IAR、Eclipse等集成开发环境。
3.测试与调试测试和调试是嵌入式系统开发的重要环节，只有将系统进行充分测试与调试，才能保证系统的正确性和稳定性。
在测试过程中，需要首先进行各个模块的单元测试，以验证系统的功能是否正常。
然后进行集成测试，交叉验证各个模块的协同工作是否正常。
最后进行耐久性测试和压力测试，确保系统能够在各种恶劣环境环境下正常运行。
二、嵌入式系统的实现1. 系统内核系统内核是嵌入式操作系统的核心，也是嵌入式系统的核心。
系统内核需要提供一个可靠的执行环境和一些重要的操作系统服务，如任务管理、内存管理、中断管理、设备驱动程序和通讯协议等。

嵌入式Web 服务器远程监控系统的设计与实现徐叶，袁敏，李国军(上海海事大学航运技术与控制工程交通行业重点实验室，上海201306)摘要：信息技术的高速发展和嵌入式系统的广泛应用给人们的生活带来了革命性的变化，嵌入式系统接入Internet 成为未来的一个趋势。
因此，本文设计一个嵌入式Web 服务器，服务器端采用HTTP 协议和CGI 技术，增加了数据库功能，在客户端的用户可以通过Internet 利用浏览器进行远程监控并且可以查看历史数据。
