Installation of open source integrated monitoring software "Zabbix"

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.

①Install repository
Setup Zabbix 6.x repository and install Zabbix Server.
Install Zabbix Agent for the monitored hosts so that Zabbix Server itself can be monitored at the same time.

Login to MySQL server as root and create MySQL database (e.g. my_zabbix_db), user (e.g. zabbix_user) and password (e.g.?WWabcd123)

Load Zabbix default schema for database

Update Zabbix configuration

Edit Zabbix server configuration file /etc/zabbix/zabbix_server.conf and update database configuration for Zabbix server to connect to database
