Zabbix Server: Installing and Configuring from Scratch

Install and configure the Zabbix server from scratch by adding the repository, installing Apache, MariaDB, and PHP, creating the Zabbix database, and starting services, with SELinux in permissive as needed.

Configure SELinux to allow Zabbix server operation by temporarily setting permissive or permanently disabling SELinux through /etc/selinux/config, rebooting, and verifying with sestatus and audit logs.

Learn to set up the Zabbix frontend: open the web console, verify prerequisites, configure database and frontend details, log in as admin, and enable monitoring by configuring hosts.

Install and configure the Zabbix agent on servers, open firewall port 150, start and enable the service, and set the agent to active or passive mode to communicate with server.

Explore the Zabbix frontend by navigating the top and bottom menus, inspecting host groups, and adjusting user profile and login options.

Learn how items provide gathered metrics by attaching them to a host in Zabbix, and how to create a host and assign it to a group for item retrieval.

Create an item for Linux host by naming it and selecting numeric float; then monitor data with filter and ensure agent and server run on ports 10050 and 10051.

Explore simple graphs for monitored numeric items, using zoom, scroll bar, and calendar widgets to adjust the displayed period, with gray areas marking outside working hours.

Create a Zabbix trigger to detect cp load too high by defining an expression tied to an item key, then review triggers in open monitoring and use filters.

Configure zabbix email parameters to enable alerts by setting the mail server, from address, and smtp authentication, then add recipient user emails.

Learn to create and configure actions in zabbix to trigger email notifications under specific conditions, detailing main configuration, operations, and action conditions for recipients such as admin users.

Explore how Zabbix wires hosts, items, and triggers to generate events when thresholds are met, drive actions and email alerts, and visualize data with graphs and front-end notifications.
