Question

My current server setup consists of Apache and Ejabberd. Apache acts as a proxy to ejabberd requests.

Now I have included another level where Nginx acts as a proxy image server in front of apache.
So Nginx process all requests by defaults and forwards all php requests to apache.

Now I am stuck with the ejabberd polling as it now communicates with nginx first instead of apache, so I keep getting a 502 Bad request.

Ho do I go about this situation.

I tired this in nginx but it does not work

proxy_set_header Host $http_host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_pass http://localhost:5280;

Answer 1

I wasn’t the one that set it up, but I have the same kind of setup currently running in a production environment. We use the same settings as you posted above, with the addition of these three.

proxy_buffering off;
tcp_nodelay on;
keepalive_timeout 55;

I think that the tcp_nodelay is the vital one as the connections are meant to be keep-alive.

If this does not fix it, please provide error logs from nginx.
