How do I prevent a Gateway Timeout with FastCGI on Nginx

Viewed 225280

I am running Django, FastCGI, and Nginx. I am creating an api of sorts that where someone can send some data via XML which I will process and then return some status codes for each node that was sent over.

The problem is that Nginx will throw a 504 Gateway Time-out if I take too long to process the XML -- I think longer than 60 seconds.

So I would like to set up Nginx so that if any requests matching the location /api will not time out for 120 seconds. What setting will accomplish that.

What I have so far is:

    # Handles all api calls
    location ^~ /api/ {
        proxy_read_timeout 120;
        proxy_connect_timeout 120;
        fastcgi_pass 127.0.0.1:8080;
    }

Edit: What I have is not working :)

Proxy timeouts are well, for proxies, not for FastCGI...

The directives that affect FastCGI timeouts are client_header_timeout, client_body_timeout and send_timeout.

Edit: Considering what's found on nginx wiki, the send_timeout directive is responsible for setting general timeout of response (which was bit misleading). For FastCGI there's fastcgi_read_timeout which is affecting the FastCGI process response timeout.

In server proxy set like that

location / {

                proxy_pass http://ip:80;                

                proxy_connect_timeout   90;
                proxy_send_timeout      90;
                proxy_read_timeout      90;

            }

In server php set like that

server {
        client_body_timeout 120;
        location = /index.php {

                #include fastcgi.conf; //example
                #fastcgi_pass unix:/run/php/php7.3-fpm.sock;//example veriosn

                fastcgi_read_timeout 120s;
       }
}
