Load balancing, missing a detail...

[Floren Munteanu]

Hi all,

I need your help with setting nginx as load balancer.
I have 2 servers, 192.168.1.2 (Web1) and 192.168.1.3 (Web2), both with
same content into /www/html directory.
Web1 has nginx installed.

http {
	...
	upstream webcluster {
		server				192.168.1.2:8000;
		server				192.168.1.3:8001;
	}

	ignore_invalid_headers			on;
 	reset_timedout_connection		on;
 	keepalive_timeout				60;

	server {
		listen				80;
		server_name				domain.com;
		root					/var/www/html;
		access_log
/var/log/nginx/localhost.access.log	main buffer=32k;
		error_log
/var/log/nginx/localhost.error.log	warn;

		client_max_body_size		10m;
		client_body_buffer_size		512k;

		proxy_buffer_size			32k;
		proxy_buffers			16 32k;
		proxy_set_header			Host $host;
		proxy_set_header			X-Real-IP
$remote_addr;
		proxy_set_header			X-Forwarded-For
$proxy_add_x_forwarded_for;

		error_page 404			= /404.html;
		error_page 500 502 503 504	= /50x.html;

		location / {
			proxy_pass
$scheme://webcluster;
			index				index.php
index.html;
		}
	}
}

What am I missing? Do I need to install another software, like
TurboGears?
All I want is to load balance 2 servers who have the exact same
content...

I looked at this example:
http://wiki.nginx.org/NginxLoadBalanceExample

If I visit http://192.168.1.2:80/, I can see the site. Not if I go to
http://192.168.1.2:8000/...
With the above configuration, I get this error message:
2009/03/23 12:10:42 [error] 27847#0: *1 connect() failed (111:
Connection refused) while connecting to upstream, client: xx.xx.xx.xx,
server: domain.com, request: "GET /forum/ HTTP/1.1", upstream:
"http://192.168.1.3:8001", host: "domain.com"
2009/03/23 12:10:42 [error] 27847#0: *1 connect() failed (111:

2009/03/23 12:10:42 [error] 27847#0: *1 no live upstreams while
connecting to upstream, client: xx.xx.xx.xx, server: domain.com,
request: "GET /forum/ HTTP/1.1", upstream: "http://webcluster", host:
"domain.com"

Please let me know what else I need to configure, in order to enable the
balancer.

Regards,
