Nginx load balancing

Server NGINX
1

Hi,

I try configure nginx load balancing with 3 nodes but never show
images or ccs style from nodes and always obtain this error:

2012/03/03 22:36:43 [error] 11321#0: *7 open()
“/usr/local/nginx/html/melchor.jpg” failed (2: No such file or
directory), client: 181.XX.XX.XX, server: edge.lb.tld, request: “GET
/melchor.jpg HTTP/1.1”, host: “edge.lb.tld”, referrer:
“http://edge.lb.tld/”
2012/03/03 22:38:16 [error] 11321#0: *19 open()
“/usr/local/nginx/html/css/style.css” failed (2: No such file or
directory), client: 200.XX.XX.XX, server: edge.lb.tld, request: “GET
/css/style.css HTTP/1.1”, host: “edge.lb.tld”, referrer:
“http://edge.lb.tld/”

This is my vhost config:

upstream edge {
server 72.XX.XX.XX:80;
server 216.XX.XX.XX:80;
server 184.XX.XX.XX:80;
}

server {
server_name edge.lb.tld;

error_log  /var/log/nginx/EDGE.error_log warn;

location / {
    proxy_set_header Host $http_host;
    proxy_pass  http://edge;
   }

}

Thanks you!

If this is the load balancer’s error log, seems like the config hasn’t
been reloaded. Try pkill -HUP nginx.

Hi Edho,

ccs.

Check the access log.

Do you clear your browser cache?

Are you sure your backends are configured properly? Have you tried
accessing the backends directly?

Perhaps the links in the site do not point to the proper
location. With a config as simple as yours, the problem is either in
the app or in the backend configuration. You have no root defined so
Nginx is trying the open the files with the default root:

/usr/local/nginx/html

I suggest you enable the debug log and trace the request:

I cleaned the cache and still images are not displayed. I am using 2
browsers for testing and always get the same result.
