## 这里不能使用nginx默认的fastcgi_params，测试的时候发现所有的页面都会跳转到首页，而且也不报错

## 貌似是SCRIPT_NAME所引起的问题，而Django好像使用的是PATH_INFO，为了避免和其他的fcgi冲突，所以新建一个django专用的fastcgi_params_django

## Python2.4 + Django 0.96 版本不需要，因为Django 0.96 还不支持SCRIPT_NAME

## 可以查看django的django\core\handlers目录下的modpython.py 文件

vi /opt/nginx/conf/fastcgi_params_django
 
fastcgi_param  PATH_INFO          $fastcgi_script_name;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
# fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
# fastcgi_param  REQUEST_URI        $request_uri;
# fastcgi_param  DOCUMENT_URI       $document_uri;
# fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$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;

2) fcgi

cd /infoware/_conf/www_tech/
 
vi start_www_tech.sh
