Icinga displays binary output to browser

Question

Can't tell if this is Icinga or nginx, but when I pull up Icinga classic web I get the binary cgi displayed on the screen.

Here's a screenshot:

It seems to be the binary data from "tag.cgi".

Here's my nginx config:

     # Icinga ---------------------------------------------------------
     location /icinga/ {
               alias                   /usr/share/webapps/icinga/;
               auth_basic              "Icinga Access";
               auth_basic_user_file    /etc/icinga/htpasswd.users;
     }

     location ~ ^/icinga/(.*)\.cgi$ {
              root           /usr/share/webapps/;
              fastcgi_pass   unix:/var/run/php-fpm/php-fpm.sock;
              include        fastcgi.conf;
              fastcgi_param  AUTH_USER          $remote_user;
              fastcgi_param  REMOTE_USER        $remote_user;
              # rewrite        ^/icinga/cgi-bin/(.*)\.cgi /$1.cgi break;
              include        /etc/nginx/fastcgi_params;
              fastcgi_index  index.php;
              fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
              auth_basic     "Icinga Access";
              auth_basic_user_file    /etc/icinga/htpasswd.users;
              }

Any idea what's happening?

Icinga main page consist of three frame

The left panel which consists of pure HTML menu.html
The top panel which consists of CGI output cgi-bin/tac.cgi?tac_header
The main window which consists of CGI output too cgi-bin/tac.cgi?tac_header

The reason your nginx spitting the binary instead CGI-generated page is, you pass the request to PHP-FPM socket. PHP FPM process only understands PHP language, but the Icinga itself written mainly in C/C++.

By default Nginx can't handle CGI, so you must add another CGI wrapper in your server, for example fcgiwrap. Icinga official wiki has example of nginx configuration in this page
