HTTP-POST Upload Buffer - Nginx Loadbalancer

Server NGINX
1

Hello Nginx-List,

i need some help setting up my Nginx Loadbalancer. I use Nginx as
Loadbalancer in front of 2 Webservers (running Nginx/PHP-FPM).

While uploading files with HTTP POST upload, these files are buffed
(temporary storaged) on my loadbalancer, is there a way pushing those
files (filesize 500k - 5m) directly to the Backend-Servers to minimize
the load on the Loadbalancer?

Any hints are welcome.

Thanks for your help.

Kind regards

Elena

Thanks for your help.
Why are you using nginx in front of nginx? Use nginx in front of two
backends with PHP-FPM. Or use haproxy, not nginx.

In either way you can try setting:

 proxy_buffering off;
This toggles response buffering, not request.

In either way you can try setting:

proxy_buffering off;

in your location where you placed the proxy configuration.

kind regards,
Malte

Thanks for your fast help.

Mikhail that is a good question, why nginx behind nginx? We Set
up these nginx with the “sorry-server” function, so our Site
goes never down when something goes wrong on our Application Servers,
a minimal version is running on our “sorry-server” than its easy to bind
in an other working Appliction server.

What about HAProxy, buffer HAProxy the HTTP UPLOAD File? Perhaps
its a good point to rethink the use of our servers…

Thanks for your answers.

Have a nice Day.

HAProxy does not buffer HTTP Posts. Unfortunately, it can’t terminate
SSL so if you’re trying to upload via an HTTPS connection you’ll need
to find a different solution altogether. FWIW, this appears to be a
frequent feature request for Nginx. I even offered to sponsor the
development, but never got a response. I’m not sure what the hangup
was.
