Thank you all for help!

I found the solution on this thread:  
http://www.ruby-forum.com/topic/1432037

The problem was that I did not wrote the form handler script.

This is my working configuration of nginx:

/usr/local/nginx/conf/nginx.conf:
----
worker_processes  20;

error_log  logs/error.log notice;

working_directory /usr/local/nginx/html;

events {
     worker_connections  1024;
}

http {
     include       mime.types;
     default_type  application/octet-stream;

     server {
         listen       80;
         client_max_body_size 100m;

         # Upload form should be submitted to this location
         location /upload {
             # Pass altered request body to this location
             upload_pass   /my-form-handler;

             # Store files to this directory
             # The directory is hashed, subdirectories 0 1 2 3 4 5 6 7 8 
9 should exist
             upload_store /tmp 1;

             # Allow uploaded files to be read only by user
             upload_store_access user:r;

             # Set specified fields in request body
             upload_set_form_field "${upload_field_name}_name" 
$upload_file_name;
             upload_set_form_field "${upload_field_name}_content_type" 
$upload_content_type;
             upload_set_form_field "${upload_field_name}_path" 
$upload_tmp_path;

             # Inform backend about hash and size of a file
             upload_aggregate_form_field "${upload_field_name}_md5" 
$upload_file_md5;
             upload_aggregate_form_field "${upload_field_name}_size" 
$upload_file_size;

             upload_pass_form_field "^submit$|^description$";
         }

        include fastcgi.conf;
        location = /my-form-handler {
           fastcgi_pass  127.0.0.1:9000;
         }

     }
}

print("GET: "); print_r($_GET);
print("POST: "); print_r($_POST);
