Upgrading the Zabbix backend from older PHP versions to PHP 7.2 or higher

When we are upgrading a Zabbix setup from Zabbix 4 to Zabbix 5, you might run into the issue that PHP 7.1 or an earlier version is installed. One of the first steps we need to do to upgrade our Zabbix setup is to make sure PHP 7.2 or higher is installed. So, let's make sure we are ready by installing PHP 7.2.

Getting ready

For this recipe, we will need our server called lar-book-zbx4. At this point, the server installed with CentOS 7 will be running Zabbix server 4.0 with PHP version 5.4.

Another working option is to have a server running Ubuntu 16.04, which already includes PHP version 7 by default. As we need version 7.2 or higher, we will upgrade this one to PHP 7.2 as well.

Also, make sure to take backups of your system and read the release notes for the new version you're installing.
