Follow the documentation from scratch for a new Zabbix setup using openSUSE, Postgres and Nginx.

You will soon notice that the docs mention php 7 configuration when php 8 is the standard.

There may be other errors in the documentation as well. Zabbix should go over its own docs from scratch, step-by-step for a new setup to be sure they are correct as errors or omissions create challenges installing Zabbix, especially for inexperienced junior administrators.
