proxy_pass, dynamic ports upstream

November 15, 2012 11:43AM
I have a requirement to be able to map a portion of a request URI to a port on a set of upstream servers. I'm hoping nginx will be able to solve this for me, but so far no luck.


Needs to be proxied to:

So the 1st portion of the URI is used as the upstreams port. However I'm having difficulty with this when I attempt to combine it with a set of upstream servers. The below configuration results in the error "no resolver defined to resolve engines".

If I specify the upstream as " proxy_pass$1/$2/?$args; " (and change nothing else) the below configuration works... however it's not being load balanced obviously.

Basically, can I load balance and use dynamic ports?


upstream engines {

server {
listen *:80;

access_log /var/log/nginx/engines.access.log main;
error_log /var/log/nginx/engines.error.log debug;

location ~/([0-9]*)/ {
rewrite ^/([0-9]*)/(.*)$ $2 break;
proxy_pass http://engines:$1/$2/?$args;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
proxy_redirect off;
proxy_buffering on;
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;
