Correct way in new versions of nginx

Turn out my first answer to this question was correct at certain time, but it turned into another pitfall - to stay up to date please check Taxing rewrite pitfalls

I have been corrected by many SE users, so the credit goes to them, but more importantly, here is the correct code:

server {
       listen         80;
       server_name    my.domain.com;
       return         301 https://$server_name$request_uri;
}

server {
       listen         443 ssl;
       server_name    my.domain.com;
       # add Strict-Transport-Security to prevent man in the middle attacks
       add_header Strict-Transport-Security "max-age=31536000" always; 

       [....]
}

The nginx plugins rely on the following URL to get the status info:

http://127.0.0.1/nginx_status

Usually, nginx does not have this URL configured to show status data.

From the documentation of the plugins, I see that nginx needs to be configured to show status data in a spesific URL.

You need to enable nginx status by adding the following lines to the site's configuration:

 server {
       listen 127.0.0.1;
       server_name localhost;
       location /nginx_status {
               stub_status on;
               access_log   off;
               allow 127.0.0.1;
               deny all;
       }
 }

Don't forget to restart the server after adding this configuration, and make sure the stus URL returns the status data.

For the complete documentation of each plugin, you can run:

munindoc nginx_request

Hope this helps.
