The solution of reporting 500 errors in the size of files uploaded by nginx

Using nginx as a reverse proxy, there is a strange problem, small files can be submitted, large files will report 500internal errors. What is the cause of this?

According to wiki, there are three configurations related to the size of uploaded files.

Client_body_buffer_size configures the cache size of the request body, if it does not match

Client_body_temp_path sets the temporary file storage path. Only when the uploaded request body exceeds the cache size will it be written to the temporary file.

Client_max_body_size sets the maximum value for uploading files

So it turns out that the cause of the problem is

1. File size exceeds client_body_buffer_size

The temporary file path of 2.client_body_temp_path does not have write permission.

The return 500 error is caused by the above two reasons.

If the uploaded file size exceeds client_max_body_size, an error of 413 entity too large will be reported.

If the reason is known, the correction will be simple.

1.client_body_buffer_size as far as possible to set a large point, this is based on speed considerations, if the setting is too small, resulting in uploaded files always have to write to disk, then the speed is too slow.

The 2.client_body_temp_path path should have writeable permissions, which is an obvious error. It's good to correct it.

3.client_max_body_size sets the maximum value for uploading files, which is based on security considerations. We think that normal users will not or will not upload files that are too large.

You can set it to client_max_body_size 100m, or you can set this value according to your own business.
