已经是监听80端口了

upstream test{
    ip_hash;
    server 127.0.0.1:8080;
    server 127.0.0.1:9090;
}
server {
    listen  80;
    server_name  test;
    index  index.html index.htm index.php index.jsp;
    location / {
	    index  index.html index.htm index.php index.jsp;
	     proxy_buffer_size 64k;
	    proxy_buffers   32 32k;
	    proxy_busy_buffers_size 128k;
	    proxy_set_header Host $host;

	    proxy_set_header X-Real-IP $remote_addr;
	    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

	    proxy_set_header HTTP_X_FORWARDED_FOR $remote_addr;
	    proxy_pass http://test;

	    error_log   /home/log/nginx/test_error.log;
	    access_log /home/log/nginx/test_access.log main;
    }

}

所以，直接访问ip，比如47.47.47.47,就直接访问到了tomcat的界面了，而不是系统的登录界面。
