How to Install and Configure Zabbix on CentOS 7

-

Zabbix is an open source monitoring tool for network services, network hardware, servers, and application. Designed to track and monitor the status of your system and servers. Zabbix offers support for many database systems - including MySQL, PostgreSQL, SQLite, and IBM DB2 - to store data. Zabbix backend is written in C, and the frontend is written in PHP.

In this tutorial, we will show you step-by-step how to install and configure an open source monitoring system Zabbix 3.4 on the CentOS 7 system. This guide will cover some topics, including installation and configuration of the LAMP Stack for our Zabbix installation, and how to change the default password for Zabbix admin web UI.
