Proxying Traffic to a Group of Servers

Info

title	info

Use a reverse proxy to route inbound traffic to particular internal servers

Follow the steps below

Info

title	nginx configuration

http

{
    upstream my_glassfish_cluster

    {
        server backend1.example.com weight=5;
        server 192.168.99.100:28080;
        server 192.168.99.100:28081 backup;
    }
}

Use weight to specify importance (1:lowest - 5:highest), use backup to specify only route to this server if all other servers in the cluster fail

Now specify the upstream group that nginx will pass requests to (can be any one of the following protocols: proxy_pass, fastcgi_pass, memcached_pass, uwsgi_pass, or scgi_pass)

   server

   {
      location /

      {
         proxy_pass http://my_glassfish_cluster;
      }

}
}

This will pass all http requests up to my_glassfish_cluster server group
