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.
FreeBSD14.1 IP(192.168.11.83)
Apache/2.4.59 (FreeBSD)
mysql Ver 8.0.35
PHP 8.3.6 (cli)
PHP 8.3.6 (fpm-fcgi)
zabbix7-server , zabbix7-agent , zabbix7-frontend Install
➁Download and install Binary Package
The port collection does not have the Zabbix 7 package, so the
zabbix7-server
zabbix7-agent
zabbix7-frontend-php83
Download and install the Binary Package.
Install Zabbix Agent for the monitored hosts so that Zabbix Server itself can be monitored at the same time.
