需要 Nginx CGI 配置方面的帮助

Question

我需要设置 nginx 配置，以便 URL“http://host/cgi-bin/hw.sh/some/path/to/data/”应该触发路径“/usr/lib/cgi-”下的 shell 脚本“hw.sh” bin/”。

现在，根据页面https://www.howtoforge.com/serving-cgi-scripts-with-nginx-on-debian-squeeze-ubuntu-11.04-p3 中提到的说明，我们需要在“.vhost”文件下设置配置。但是我在路径“/etc/nginx/sites-available/default”下已经存在一个默认文件，而不是 .vhost 文件。

当我使用相同的配置时，我得到 HTTP/1.1 403 Forbidden 错误。我已确保该脚本也需要可执行权限。以下是 nginx 日志中收到的错误。

FastCGI sent in stderr: "Cannot get script name, are DOCUMENT_ROOT and SCRIPT_NAME (or SCRIPT_FILENAME) set and is the script executable?"
while reading response header from upstream, 
client: host_ip, server: localhost, 
request: "HEAD /cgi-bin/hw.sh/some/path/to/data/ HTTP/1.1", 
upstream: "fastcgi://unix:/var/run/fcgiwrap.socket:", host: "host_ip"

我需要帮助来编写正确的配置，以便我上面的 URL 执行上述路径下的 hw.sh 脚本并返回正确的输出。有人可以帮我吗？

以下是我在默认文件下使用的配置。

server {
        listen 80 default_server;
[...]    
location /cgi-bin/ {
         # Disable gzip (it makes scripts feel slower since they have to complete
         # before getting gzipped)
         gzip off;
         # Set the root to /usr/lib (inside this location this means that we are
         # giving access to the files under /usr/lib/cgi-bin)
         root  /usr/lib;
         # Fastcgi socket
         fastcgi_pass  unix:/var/run/fcgiwrap.socket;
         # Fastcgi parameters, include the standard ones
         include /etc/nginx/fastcgi_params;
         # Adjust non standard parameters (SCRIPT_FILENAME)
         fastcgi_param SCRIPT_FILENAME  $document_root$fastcgi_script_name;
       }
[...]
}

行“fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;”在配置中导致问题。 当我将其更改为“fastcgi_param SCRIPT_FILENAME $request_filename;”时，一切都按预期工作。
