How to enable pagespeedy admin pages?

after ty hard i got it, install the nginx (from source) with passenger and google pagespeed. I've setup the nginx conf and it worked but, i dint see any diference using pagespeedy(my scripts stills unminified). Studyng a little i saw that PGSPD have an admin page where i can see what is happening and configure somethings. So i can't access this admin pages here is my nginx conf:

#user  nobody;
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    passenger_root /home/icaro/.rbenv/versions/2.2.2/lib/ruby/gems/2.2.0/gems/passenger-5.0.15;
    passenger_ruby /home/icaro/.rbenv/shims/ruby;
    sendfile        on;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    keepalive_timeout  65;
    gzip  on;
    server {
        listen 80;
        pagespeed on;
        pagespeed FileCachePath /tmp/pgsp;
        passenger_enabled on;
        passenger_app_env production;
        root /home/icaro/icarodroplet/public;
    }
    server{
        pagespeed on;
        pagespeed FileCachePath /tmp/pgsp;
        location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" {
          add_header "" "";
        }
        location ~ "^/pagespeed_static/" { }
        location ~ "^/ngx_pagespeed_beacon$" { }
        location /ngx_pagespeed_statistics { allow 127.0.0.1; allow all; }
        location /ngx_pagespeed_global_statistics { allow 127.0.0.1; allow all; }
        location /ngx_pagespeed_message { allow 127.0.0.1; allow all; }
        location /pagespeed_console { allow 127.0.0.1; allow all; }
        location ~ ^/pagespeed_admin { allow 127.0.0.1; allow all; }
        location ~ ^/pagespeed_global_admin { allow 127.0.0.1; allow all; }
    }
}

that's right? why i cant see differences there is a way to test the pagespeed? how can i access the admin pages?
