nginx and apache and php how to hide http header version information

1. nginx hidden header version information method

        edits the nginx.conf configuration file, adding the following line within http{}

http {
       ... 
      server_tokens off;
       ... 
     }    

        edits the php-fpm configuration file, fastcgi.conf or fcgi.conf

Find:

fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

To:

fastcgi_param SERVER_SOFTWARE nginx;

Restart the nginx service to take effect

[root@xmydlinux conf]# curl --head 127.0.0.1                
HTTP/1.1 200 OK 
Server: nginx
Content-Type: text/html; charset=utf-8 
Connection: keep-alive
