**lighttpd+fastcgi+C语言                                                       **

**一、简述**

记--lighttpd+fastcgi。fastcgi相对于传统cgi，可以实现常驻进程的效果。传统cgi是收到请求之后才会启动cgi程序，处理完成后就退出，这对响应速度、资源不断的申请和释放，状态的保持有影响。

**二、安装lighttpd**

2.1 下载lighttpd

官网：[https://download.lighttpd.net/lighttpd][https_download.lighttpd.net_lighttpd]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70][]

2.2 解压

tar xzf lighttpd-1.4.59.tar.gz

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 1][]

2.3 创建lighttpd目录，后面用作lighttpd安装路径

![20210605203047165.png][]

2.4 安装

配置：

执行./configure -C --prefix=/home/liang/lighttpd/ --without-pcre --without-zlib

\--without-pcre --without-zlib 附带这两个参数是因为例子中的ubuntu没有安装pcre和zlib，如果已经安装，或需要请自行安装，然后就不需要这两个参数了

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 3][]

执行make

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 4][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 5][]

执行make install

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 6][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 7][]

成功安装到指定的目录：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 8][]

**三、配置lighttpd**

3.1 拷贝一份配置

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 9][]

3.2 创建相关目录，后面修改配置会使用到

mkdir cache log sockets vhosts www

log目录存放lighttpd相关日志

sockets目录存放的是与fcgi通信的本地域socket

www用作存放html相关，cgi程序相关

![2021060520590440.png][]

3.3 修改配置

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 10][]

修改lighttpd.conf

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 11][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 12][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 13][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 14][]

修改modules.conf

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 15][]

修改fastcgi.conf

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 16][]

fastcgi.server = ( 
    	"test.fcgi" => 
    	((
    		"bin-path" => "/home/liang/lighttpd/www/test.fcgi",
    		"socket" => socket_dir + "/test.socket",
    		"min-procs" => 0,
    		"max-procs" => 1,
    		"bin-enviroment" => (
    			"REAL_SCRIPT_NAME" => ""			
    			),
    		"check-local" => "disable"
    	))
      )

修改cgi.conf使得可以使用cgi

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 17][]

3.4 启动lighttpd

执行sudo /home/liang/lighttpd/sbin/lighttpd -f /home/liang/lighttpd/config/lighttpd.conf

使用-f参数指定配置文件：/home/liang/lighttpd/config/lighttpd.conf

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 18][]  
还没有编写test.fcgi, 暂时屏蔽fcgi，后面写好test.fcgi,再打开

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 19][]

成功运行

![20210605213252484.png][]

在 /home/liang/lighttpd/www/下放一个index.html以便启动lighttpd测试, 使用浏览器访问127.0.0.1/index.html即可看到如下页面

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 20][]

**四、安装fastcgi**

**4.1 下载fcgi-2.4.1.tar.gz**

**链接1：**[https://github.com/Seaworth/resources/tree/master/fastCGI%E5%AE%89%E8%A3%85%E5%8C%85][https_github.com_Seaworth_resources_tree_master_fastCGI_E5_AE_89_E8_A3_85_E5_8C_85]

链接2：下载：https://wwa.lanzoui.com/b0c9czcbc 密码:1vyi

4.2 解压:tar xzf **fcgi-2.4.1.tar.gz**

![20210627212542809.png][]

4.3 添加头文件引用

修改fcgio.cpp,添加引用stdio.h头文件，不然后面make会报找不到EOF错误

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 21][]

4.4 编译

./configure（默认安装位置/usr/local/bin, /usr/local/lib/）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 22][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 23][]

执行make

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 24][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 25][]

sudo make install

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 26][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 27][]

安装后可执行文件在/usr/local/bin, fcgi库文件在/usr/local/lib/ ，头文件在/usr/local/include/

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 28][]

编写fcgi程序需要使用到fcgi\_stdio.h和libfcgi.so

**五、测试fastcgi程序**

简单的测试程序，如果需要更符合的使用场景，可以进行个性化配置。

5.1 测试代码

#include <stdio.h>
    #include <stdlib.h>
    #include "fcgi_stdio.h"
    
    int main(void)
    {
    	int count = 0;
    
    	while(FCGI_Accept() >= 0) {
    		printf("Content-type: text/html\r\n\r\n");
    		printf("Hello Fastcgi. count=%d", ++count);
    	}
    	
    	return 0;
    }

5.2 编译

gcc fcgi.c -o test.fcgi -lfcgi

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 29][]

5.3 测试结果

![20210627225715210.gif][]

注意：需要在配置中启用fcgi，并重新启动lighttpd服务器，如果还是不能访问fcgi程序，可以尝试重启ubuntu。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 30][]

**六、 测试传统cgi程序**

测试代码：

#include <stdio.h>
    
    int main(void)
    {
    	//printf("Content-type: text/html\r\n");
    	printf("hello cgi. %s\r\n", __DATE__);
    	return 0;
    }

编译：gcc cgi.c -o test.cgi

如果test.cgi没有中执行权限就需要给权限，chmod a+x test.cgi

测试结果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L25hbmZlaWJ1eWk_size_16_color_FFFFFF_t_70 31][]

此时查看所有进程，是没有test.cgi进程的，因为它已经退出了,只有在被调用的瞬间启动，处理完成就退出，ps ef | grep test.fcgi

附：

结束lighttpd：

pkill lighttpd  
killall lighttpd
