Hi folks,

using fpm for zabbix is actually pretty easy. Something like this will do

apt install php7.4-fpm
a2dismod php7.4
a2enconf php7.4-fpm
a2enmod proxy_fcgi
a2dismod mpm_prefork
a2enmod mpm_event
a2enmod http2
systemctl restart apache2

Problem is, all the php options set in zabbix-frontend-php.conf are lost, since the mod_php7 module is not in anymore.

Zabbix lacks a modular approach to set the lost options for both mod_php and fpm, making sure they are not lost on the next major Zabbix or PHP upgrade.
