Hello TimK,

you have installed php, but now have to make web browser use it.

it would be good idea to check if apache is using php => 7.2
you can do this with phpinfo.php file, - search how to do this in google for first site with keyword "how-to-check-the-php-version-on-linux"

Please also consider that zabbix might generate much iops and can kill your Rpi SD card very soon.

Sebastian,

Thanks for pointing me in the right direction. After a little google-fu I was able to fix the problem.

Also, thanks for reminding me about the iops. Yes, it may be an issue with the SD card. I may configure the rasp pi to boot off of a spare hard drive instead.

This is mostly a test system for me to monitor a few devices on my home network as a proof of concept. I may end up installing it on an old laptop running Linux if I want to do more. But in the meantime, I'll make a backup of the SD card just in case.

Here is what I did (just in case anyone else has the same problem).

I created a phpinfo.php file in /var/www/html that was simply:

<?php
phpinfo();
?>

In my web browser, I navigated to http://<ip_address>/phpinfo.php

This showed that Apache was indeed using PHP 7.0 although running php -v in the CLI still reported 7.4.8

I ran:

sudo a2dismod php7.0
sudo service apache2 restart

This time when I refreshed the web browser, I was just presented with the contents of the phpinfo.php file, meaning that Apache was not using php at all.

I then ran:

sudo a2enmod php7.4
sudo service apache2 restart

This time after refreshing the browser, Apache was correctly using php 7.4.8

I then navigated to http://<ip_address>/zabbix which now correctly presents me with the Zabbix welcome page.
