How to install PHP 7.2 on CentOS 7/RHEL 7

How do I Install PHP 7.2 on CentOS 7 server? How can I setup and install PHP 7.2 on RHEL 7 server along with Nginx web server? How do I configure PHP-fpm version 7.2 with Nginx server running on a CentOS / Red Hat Enterprise Linux version 7?

Hello. I followed the tutorial:

It all seems to work, but only php72 has now been installed as an executable. Trying php -v gives errors:

php --version
-bash: /usr/bin/php: No such file or directory

How can php72 become a synonym for php itself? Thanks.
