[转]nginx＋fastcgi+c/c++搭建高性能Web框架

FROM : http://blog.csdn.net/marising/article/details/3932938

 

1.Nginx

1.1.安装

  1. Nginx 的中文维基 http://wiki.codemongers.com/NginxChs 下载 Nginx 0.6.26（开发版）（请下载最新版本）
  2. tar zxvf nginx-0.6.26.tar.gz
  3. ./configure，注意了类似checking for *** ... not found项，可能是依赖包没有，则需要安装依赖包
  4. 缺少PCRE，sudo apt-get install pcre安装。或者去：http://www.pcre.org/
  5. 如果缺少OpenSSL，sudo apt-get install libssl-dev，或者去：http://www.openssl.org
  6. 如果缺少zlib，可以apt-get install zlib1g，或者http://www.zlib.net/
  7. 配置请参考：http://wiki.codemongers.com/NginxChsInstall 可以选择安装模块
  8. make & make install
  9. 默认安装在/usr/local/nginx下

1.2.管理

  1. 执行选项
    -c </path/to/config> 为 Nginx 指定一个配置文件，来代替缺省的。
    -t 不运行，而仅仅测试配置文件。nginx 将检查配置文件的语法的正确性，并尝试打开配置文件中所引用到的文件。
    -v 显示 nginx 的版本。
    -V 显示 nginx 的版本，编译器版本和配置参数。
  2. 检查配置文件 
    $ sudo nginx -t
2008/03/12 19:15:11 info 12384#0: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
2008/03/12 19:15:11 info 12384#0: the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully
  3. 启动 
    /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
  4. 查看nginx主进程号 
    $ ps -ef | grep "nginx: master process"
    
 | grep -v "grep"

    
 | awk -F ' ' '{print $2}

    
26010
  5. 重新加载配置文件 
    $sudo kill -HUP 26010

    通过系统的信号控制 Nginx
    可以使用信号系统来控制主进程。默认，nginx 将其主进程的 pid 写入到 /usr/local/nginx/logs/nginx.pid 文件中。通过传递参数给 ./configure 或使用 pid 指令，来改变该文件的位置。
    主进程可以处理以下的信号：

    命令说明备注
    TERM, INT 快速关闭  
    QUIT 从容关闭  
    HUP 重载配置 用新的配置开始新的工作进程    从容关闭旧的工作进程
    USR1 重新打开日志文件  
    USR2 平滑升级可执行程序  
    WINCH 从容关闭工作进程  
  6. 默认目录
    主目录：/usr/local/nginx/
    配置目录：/usr/local/nginx/conf/
    root目录：/usr/local/nginx/html/
    可执行文件路径：/usr/local/nginx/sbin/

2.FastCGI

2.1.安装lighttpd的spawn-fastcgi

    下载http://www.lighttpd.net/download/lighttpd-1.4.19.tar.gz

./configure
    make
    cp ./src/spawn-fcgi /usr/local/nginx/sbin/

2.2.安装fastcgi库

    下载http://www.fastcgi.com/dist/fcgi.tar.gz

./configure
    make
    make install

2.3.Hello world 

#include <iostream>
#include <fcgi_stdio.h>

using namespace std;

int main()
{

    /* Initialization Code */
    int count = 0;


    /* Start of response loop */
    while (FCGI_Accept() >= 0)
    {
        //* body of response loop /*/
        printf("Content-type: text/html/r/n"
               "/r/n"
                ""
                "FastCGI Hello/! (C, fcgi_stdio library)"
                "Request number %d running on host %s "
                "Process ID: %d/n",
                /++count,
                getenv("SERVER_NAME"), getpid());
    }




    /* End of response loop */
    return 0;


}

编译后为FastCGISameple

2.4.启动Spawn-cgi

/usr/local/nginx/sbin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 25 -u www -f /usr/local/nginx/fcgi/FactCGISample

2.5.修改Nginx配置文件

   vi /usr/local/nginx/conf/nginx.conf

location ~ /.cgi$

{    
      fastcgi_pass 127.0.0.1:9000; 
      fastcgi_index index.cgi;
      fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
      include fastcgi_params;
}

  别忘了，重新加载配置文件

$sudo kill -HUP 26010

打开浏览器，输入http://localhost/1.cgi ，就显示

FastCGI Hello! (C, fcgi_stdio library)Request number 1 running on host localhost Process




 ID: 25473

3.webbench压力测试工具

下载：http://home.tiscali.cz:8080/~cz210552/distfiles/webbench-1.5.tar.gz

安装：

tar zxvf webbench-1.5.tar.gz
cd webbench-1.5


make && make install

使用：

webbench -c 500 -t 30 http://127.0.0.1/test.jpg

500是并发连接数，30是时间单位是秒

 

用ab测试的结果，在我的虚拟机上，看起来性能很不错

(Apache Bench是Apache自带的工具包)
