Migration of BOA Server

2022-08-03 06:32:00 【Certainly is food package】

概述

BOA是一种非常小巧的web服务器,Used to handle client-side or browser-sidehttp请求,Because of its small size,性能优秀,Therefore, it is suitable for embedded systems.

BOA简介

其可执行代码只有大约60KB左右,Boais a single taskHTTP服务器,Boa只能依次完成用户的请求,而不会fork出新的进程来处理并发连接请求.Boa支持CGI.
Boa的设计目标是速度和安全.（CGI只是一个进程,用来提供接口）,Automatic directory generation and automatic file guns for stitching.
BoaThe main design goals are speed and safety.安全性在“Cannot be destroyed by malicious users”的意义上,不是“Fine-grained access control and encrypted communications”.

特点：可靠性和可移植性,BoaNot as a powerful server.
开发平台：GNU / Linuxis the current development platform.

BOA移植过程

下载boa源码,本文使用的是

1.进入boa官网下载
http://www.boa.org/ 

2.CSDN直接下载
https://download.csdn.net/download/qq_42368385/86267519

解压文件,并进入./boa-0.94.13/src目录

cd ./boa-0.94.13/src/

执行./configure配置编译环境

[email protected]:~/boa-0.94.13/src$ ./configure

make编译源码

[email protected]:~/boa-0.94.13/src$ make

make编译会出现错误：
compat.h:120:30: note: in definition of macro ‘TIMEZONE_OFFSET’
#define TIMEZONE_OFFSET(foo) foo##->tm_gmtoff
^
make: *** [util.o] Error 1

解决方法：
（1）修改compat.h 的第120行代码
（2）修改boa.c 的第225行代码

[email protected]:~/boa-0.94.13/src$ vim compat.h +120
将
#define TIMEZONE_OFFSET(foo) foo##->tm_gmtoff        
改成：
#define TIMEZONE_OFFSET(foo) (foo)->tm_gmtoff     

[email protected]:~/boa-0.94.13/src$ vim boa.c +225
Comment out these lines of code：
 if (setuid(0) != -1) {
 	DIE("icky Linux kernel bug!");
 }
 改为：
 #if 0     //注释掉
	if (setuid(0) != -1) {
 		DIE("icky Linux kernel bug!");
	}
#endif 
Check out the file you just compiled,重新编译
[email protected]:~/boa-0.94.13/src$ make clean
[email protected]:~/boa-0.94.13/src$ make

5.创建boa安装目录 /boa

mkdir -p /home/linux/boa /home/linux/boa/www /home/linux/boa/cgi-bin /home/linux/boa/log

6.Copy the one generated by the previous compilationboa file to createboa文件夹下,修改boa-0.94.13文件夹下的defines.h文件中的SERVER_ROOT,Make it point to the file path created earlier

[email protected]:~/boa-0.94.13/src$ sudo cp boa /home/linux/boa/

[email protected]:~/boa-0.94.13/src$ vi defines.h +30
将第30行：
#define SERVER_ROOT "/etc/boa"
The specified path is changed to the file path created earlier：
#define SERVER_ROOT "/home/linux/boa"

7.Copy the necessary files to the installation directory

[email protected]:~/boa-0.94.13/src$ cp boa /home/linux/boa/
[email protected]:~/boa-0.94.13/src$ cp boa_indexer /home/linux/boa/
[email protected]:~/boa-0.94.13/src$ cp /etc/mime.types /home/linux/boa/
[email protected]:~/boa-0.94.13/src$ cd ..
[email protected]:~/boa-0.94.13$ cp boa.conf /home/linux/boa/

8.修改boa配置文件

[email protected]:~/boa$ ls
boa  boa.conf  boa_indexer  cgi-bin  log  mime.types  www
[email protected]:~/boa$ cp boa.conf boa.conf.back
[email protected]:~/boa$ cat boa.conf.back | grep -v "#" | grep -v "^$" > boa.conf

[email protected]:~/boa$ vim boa.conf
将内容改为：

Port 80
User 0
Group 0
ErrorLog /home/linux/boa/log/error_log
AccessLog /home/linux/boa/log/access_log
DocumentRoot /home/linux/boa/www
UserDir public_html
DirectoryIndex index.html
DirectoryMaker /home/linux/boa/boa_indexer
KeepAliveMax 1000
KeepAliveTimeout 10
MimeTypes /home/linux/boa/mime.types
DefaultType text/plain
CGIPath /bin:/usr/bin:/usr/local/bin
Alias /doc /usr/doc
ScriptAlias /cgi-bin/ /home/linux/boa/cgi-bin/

9.index.html页面的实现

[email protected]:~/boa$ cd www/
[email protected]:~/boa/www$ vi index.html

在index.html中添加以下内容

<html>
        <body>
                <h3>this is a test!</h3><br/>
                        <img src="image.jpg"/>
                <h3>tree picture</h3><br/>
 
                <a href="/cgi-bin/test.cgi">to cgi page</a>
        </body>
</html>

Find a picture to put it withindex.html的同级目录下

10.测试用的test.cgi生成

[email protected]:~/boa$ cd cgi-bin/
[email protected]:~/boa/cgi-bin$ vi test.c

添加以下内容：

#include <stdio.h>  
int main()  
{  
	printf("Content-type:text/html\n\n"); //这句一定要加上  
	printf("<html><body>");  
	printf("<font style=\"color:red; font-size:30px;\">Hello, CGI!</font><br/>");  
	printf("<a href=\"/index.html\">return index.html</a>");  
	printf("</body></html>");  
	return 0;  
}

编译生成test.cgi

[email protected]:~/boa/cgi-bin$ gcc -o test.cgi test.c
[email protected]:~/boa/cgi-bin$ ls
test.c  test.cgi

11.查看目录

[email protected]:~/boa$ tree
.
├── boa
├── boa.conf
├── boa.conf.back
├── boa_indexer
├── cgi-bin
│   ├── test.c
│   └── test.cgi
├── log
├── mime.types
└── www
    ├── core
    ├── image.jpg
    └── index.html
3 directories, 10 files

12.验证效果
