In this tutorial we will install PHP 7.1.19 on the perfect server environment with ISPConfig on Debian 8. PHP is installed in optional mode, so it is available for web hosts in PHP-FPM and FastCGI modes, in addition to the default version of 5.6.x.

In this tutorial, I will show you how to set up a secondary name server for our domain names if you only have one IP address. We use ISPConfig in a server environment and use an external, free name server service.
