File uploads in node.js as nginx upstream

Question

I have a node app running through nginx as an upstream and doing file uploads up to 2GB.

In nginx, I have client_max_body_size set to 2G and increased client_body_buffer_size to 2mb .

I find that when uploading large files (eg, 1gb), it will hang in nginx for a really long time (30 seconds +) until it makes it to node (which actually handles the upload).

I have logs in nginx for [warn] 9624#0: *586 a client request body is buffered to a temporary file /usr/share/nginx/client_body_temp/0000000032

Any ideas why it's not passing to node right away or how I can optimize this?

Answer 1

自从提出这个问题以来已经proxy_request_buffer ，但是 nginx 有可以设置为关闭的proxy_request_buffer （默认情况下是打开的）。
