Ubuntu24.04 ; Zabbix7 Install

Installation of open source integrated monitoring software "Zabbix7".

Zabbix is an open source integrated monitoring software for centralized monitoring of servers, networks and applications. It provides monitoring, fault detection and notification functions required for integrated monitoring. With Zabbix agent and SNMP support for many platforms, you can monitor your entire system with a single Zabbix.

To run Zabbix, you will need the PHP programming language, MySQL/MariaDB as a database server, and a web server such as Apache or Nginx.
In this case, we will assume that all of the following conditions have already been configured.

This time we will install Zabbix 7.0 LTS released on 06/04/2024 in the following environment.
Apache/2.4.58
10.11.8-MariaDB
PHP 8.3.6
PHP-fpm

zabbix7-server , zabbix7-agent , zabbix7-frontend Install

Install Repository
