Hide Nginx and PHP version numbers in Linux

Nginx Hide Version Number:

1, enter the Nginx configuration file directory (this directory according to the installation decision), with the nano edit open

Nano nginx.conf

Add Server_tokens off in HTTP {-}; Such as:

HTTP {
...... Omitted
Sendfile on;
Tcp_nopush on;
Keepalive_timeout 60;
Tcp_nodelay on;
Server_tokens off;
... omit.
}

2, edit php-fpm configuration file, such as fastcgi.conf or fcgi.conf (this profile name can also be customized, according to the specific file name modified):
Found it:

Fastcgi_param server_software nginx/$nginx _version;

To

Fastcgi_param Server_software Nginx;

3, Reload Nginx configuration:

/etc/init.d/nginx Reload

This completely hides the Nginx version number, that is, 404, 501 and other pages will not show the Nginx version.

PHP Hidden version Number:

PHP.ini expose_php = on to expose_php = off is done
