I'm trying to use upstream config to loadbalance my fastcgi requests to 4 php-fpm pools. But it seems that fastcgi_pass doesn't recognize upstream configuration, throwing an error when I exec nginx -t:

nginx: [emerg] invalid host in upstream "http://phpbackend" in /etc/nginx/includes/php5-fpm.conf:4
nginx: configuration file /etc/nginx/nginx.conf test failed

I'm using the last mainline version: 1.7.1.

My config is divided into 5 files:

# /etc/nginx/nginx.conf
user www-data;
worker_processes 2;
pid /run/;

events {
	worker_connections 4096;
	multi_accept on;
	use epoll;

What I'm doing wrong?

Resolution: invalid
Status: newclosed

The "fastcgi_pass" can't use "http" as a protocol, hence the error.

Please make sure to use mailing list for further questions. Trac is a wrong place to ask questions, it's to report/track bugs.

I'm very sorry for this post Maxim... Next time I'll use mailling lists.
