What must you do if one of the frontend prerequisites is not met?

When one of the frontend prerequisites for Zabbix is not met, addressing the issue is essential to ensure that the installation and functionality of the Zabbix software are optimal. The frontend relies on various server configurations, specifically those related to PHP and web servers. If a prerequisite is not satisfied, simply ignoring the issue or attempting to continue with installation can lead to incomplete setups, performance problems, or functional limitations that hinder the use of Zabbix.

By fixing the underlying problem and then restarting the PHP-FPM service, you ensure that the changes take effect and that the system can operate correctly. This action reflects good system administration practices, fostering a stable working environment for Zabbix to function as expected. Additionally, the reliance on proper PHP environments, including configurations like memory limits, execution time, and modules, highlights the importance of meeting all prerequisites.

Consulting the user manual or reaching out to support can be part of the troubleshooting process, but the primary action should always be to rectify any issues to enable a smooth installation and operation, making sure the Zabbix frontend works as intended.
