多节点池转发

1.根据URL

worker_processes  1;
    events {
        worker_connections  1024;
    }
    http {
    	include       mime.types;
      	default_type  application/octet-stream;
    	sendfile        on;
    	keepalive_timeout  65;
    	upstream static_server_pools {
            server 10.0.0.7:80 weight=1;

   	}
    	upstream upload_server_pools {
            server 10.0.0.8:80 weight=1;

    	}
        server {
            listen       80;
            server_name  www.peterwang.org;
            location /static/ {
            proxy_pass http://static_server_pools;
            include proxy.conf;
            }
        location /upload/ {
             proxy_pass http://upload_server_pools;
             include proxy.conf;
            }
        }
    }

vim /application/nginx/conf/proxy.conf

proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_connect_timeout 60;
proxy_send_timeout 60;
proxy_read_timeout 60;
proxy_buffer_size 32k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;

2.根据用户设备

worker_processes  1;
    events {
        worker_connections  1024;
    }
    http {
    	include       mime.types;
    	default_type  application/octet-stream;
    	sendfile        on;
    	keepalive_timeout  65;
    	upstream static_server_pools {
            server 10.0.0.7:80 weight=1;

    	}
    	upstream upload_server_pools {
            server 10.0.0.8:80 weight=1;

	}
   	server {
            listen       80;
            server_name  www.etiantian.org;
            location / {
            	if ($http_user_agent ~* "MSIE")
        	{
            	proxy_pass http://static_server_pools;
        	}
            	if ($http_user_agent ~* "Firefox")
        	{
            	proxy_pass http://upload_server_pools;
        	}
            	include proxy.conf;
            }
	}
}
