PHP 7.2 switch script messes with server settings

[n8v8r]

CentOS Linux  7.4.1708 (Core)
Kernel 3.10.0-693.17.1.el7.x86_64
Apache & Varnish Cache & Nginx Reverse Proxy
Apache/2.4.29
nginx/1.12.2
PHP 5.6.30 ==>> 7.2.0
suPHP version 0.7.2

After the switch script finished httpd would fail to start and complain about port 80 already being occupied (nginx). Rebuilding the configuration Apache & Varnish Cache & Nginx Reverse Proxy did not cure the issue. The solution then was to rebuild httpd only first and then again Apache & Varnish Cache & Nginx Reverse Proxy.

PHP 7.2.0 ==>> 7.1.9

switch to 7.1.9 did not mess with the server settings
