How to disable version display information in Nginx?

The method is very simple, just add the "server_less tokens" parameter in the HTTP of nginx.conf

For example:

http {  
    include       mime.types;  
    default_type  application/octet-stream;  
    server_tokens off;      
    client_header_timeout       3m;  
    client_body_timeout         3m;  
    send_timeout                3m;  
    ...
}
