Nignx is a very great web server and load banlancer. In my “Nginx Server” category have more about nginx.
If you want to configure multiple mongrel clusters to be used with multiple domains or sub-domains then define multiple upstream blocks and server blocks and add it to the same nginx config file.
master config part:
worker_processes 20;
#error_log logs/error.log info;
#pid logs/nginx.pid;

events {
use epoll;
worker_connections 51200;
}
http {

‘"$status" $body_bytes_sent "$http_referer" ‘
‘"$http_user_agent" "$http_x_forwarded_for" "$gzip_ratio"’;

Multiple domains load banlancer config part:
upstream www.domain1.com {
server 192.168.10.11:80;
server 192.168.10.12:80;
}
server
{
listen 80;
server_name www.domain1.com;
location / {
proxy_pass http://www.domain1.com;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
upstream www.domain2.com {
server 192.168.10.21:80;
server 192.168.10.22:80;
}
server
{
listen 80;
server_name www.domain2.com;
location / {
proxy_pass http://www.domain2.com;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}

}
