HI, I have compiled newest version of nginx (nginx/1.1.1) with nginx upload module (v 2.2.0), also the example config (nginx.conf) was copied from [GitHub - vkholodkov/nginx-upload-module: A module for nginx web server for handling file uploads using multipart/form-data encoding (RFC 1867).](https://github.com/vkholodkov/nginx-upload-module) into nginx direcoty. The html form is also copied from this location. So the installation and configuration is oryginal now without any changes. I’m getting some errors while uploading the file; The html form: ‘502 Bad Gateway’; The nginx error.log (/usr/local/nginx/logs/error.log): * * * ## 2011/09/05 08:35:15 [error] 21161#0: \*6 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.0.165, server: , request: “POST /upload HTTP/1.1”, upstream: “[http://127.0.0.1:8080/upload](http://127.0.0.1:8080/upload)”, host: “192.168.0.127”, referrer: “[http://192.168.0.127/http/upload.html](http://192.168.0.127/http/upload.html)” Maybe it’s a problem of my wrong understanding how does it works, I do not understand why in this example config the proxy\_pass is going through local 8080 port but the server in this configuration is not listening on such port. Please help. – best regards Piotr P. ---

I found the solution on this thread: [http://www.ruby-forum.com/topic/1432037](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; } } ``` ## } ## /usr/local/nginx/html/my-form-handler \ * * * – best regards Piotr P.
