fastcgi（一）

首先安装 fastcgi 开发包 ...

#wget http://www.fastcgi.com/dist/fcgi-current.tar.gz

#tar -zxvf fcgi-current.tar.gz

#cd fcgi-2.4.0

#./configure --prefix=/usr/local/fastcgi/

#make && make install

写一个简单的fcgi 程序

#vim hello.c 

内容如下：

1. #include </usr/local/fastcgi/include/fcgi_stdio.h>  
2.   
3. int main(void){  
4.     while( FCGI_Accept() >= 0){  
5.         printf( "Content-Type: text/html\r\n" );  
6.         printf("\r\n");  
7.         printf( "Hello world in C\n" );  
8.     }  
9. }  

#gcc -o hello.fcgi hello.c -L /usr/local/fastcgi/lib/ -lfcgi

[root@lxp2 Downloads]# tar -xf nginx-1.0.10.tar.gz 
[root@lxp2 Downloads]# cd nginx-1.0.10
[root@lxp2 nginx-1.0.10]# ./configure 

checking for PCRE library ... not found

./configure: error: the HTTP rewrite module requires the PCRE library.
You can either disable the module by using --without-http_rewrite_module
option, or install the PCRE library into the system, or build the PCRE library
statically from the source with nginx by using --with-pcre=<path> option.

这说明系统中缺少PCRE库。该库是实现正则表达式的基础，如果缺少此库，nginx无法支持HTTP中的URL重写功能。如果你不需要此功能，可以在执行编译配置脚本时加入“--without-http_rewrite_module”。但是，这里我们需要这项功能。于是下载PCRE库。

 

2.下载安装PCRE库：

PCRE库是实现Perl式正则表达式的基础。如果系统中缺少此库需要编译安装。可以从著名的开源软件网站sourceforge上下载：http://sourceforge.net/projects/pcre/files/pcre/。目前最新版本是8.20。

仍然是下载后解压、配置、编译和安装：

  nginx path prefix: "/usr/local/nginx"
  nginx binary file: "/usr/local/nginx/sbin/nginx"
  nginx configuration prefix: "/usr/local/nginx/conf"
  nginx configuration file: "/usr/local/nginx/conf/nginx.conf"
  nginx pid file: "/usr/local/nginx/logs/nginx.pid"
  nginx error log file: "/usr/local/nginx/logs/error.log"
  nginx http access log file: "/usr/local/nginx/logs/access.log"
  nginx http client request body temporary files: "client_body_temp"
  nginx http proxy temporary files: "proxy_temp"
  nginx http fastcgi temporary files: "fastcgi_temp"
  nginx http uwsgi temporary files: "uwsgi_temp"
  nginx http scgi temporary files: "scgi_temp"
[root@lxp2 nginx-1.0.10]# make

[root@lxp2 nginx-1.0.10]# sudo make install 

nginx.conf的配置要修改

1. server {  
2.     listen 80;  
3.     location ~ \.fcgi$ {  
4.             root           /srv/www;  
5.             fastcgi_pass   127.0.0.1:9002;  
6.             include        fastcgi_params;  
7.     }  
8. }  

重启nginx ,然后用fastcgi 启动程序，同时监听 9002 端口

# /usr/local/fastcgi/bin/cgi-fcgi -start -connect 127.0.0.1:9002 /srv/html/cgi/hello.fcgi
