nginx+fastcgi

fedora x64
配置nginx

location / {
root   /home/mass/www;
fastcgi_pass   127.0.0.1:9000;
fastcgi_index  index;
fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
include        fastcgi_params;
}

主要的是要指定fastcgi_pass 意味着把web请求重定向到这个地址
测试用fastcgi,echo.c来自fastcgi.com，编译

gcc -o echo -lfcgi echo.c

然后执行

spawn-fcgi -a 127.0.0.1 -p 9000 -f ./echo

spawn-fcgi是一个执行fastcgi程序的程序，fedora 可以通过yum install spawn-fcgi安装

之后通过浏览器访问
结果如下：

Request environment:

FCGI_ROLE=RESPONDER
SCRIPT_FILENAME=/scripts/hello
QUERY_STRING=
REQUEST_METHOD=GET
CONTENT_TYPE=
CONTENT_LENGTH=
SCRIPT_NAME=/hello
REQUEST_URI=/hello

DOCUMENT_ROOT=/home/mass/www

SERVER_SOFTWARE=nginx/0.8.53

HTTP_CACHE_CONTROL=max-age=0

可以看到，当访问的路径是/hello时，环境变量SCRIPT_NAME，REQUEST_URI,DOCUMENT_URI均为/hello.

nginx 内置的环境变量在/etc/nginx/fastcgi.conf中

fastcgi_param  SCRIPT_FILENAME    $document_root$fastcgi_script_name;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;
