How to Install Zabbix 6.0 LTS on Red Hat Enterprise Linux 8

Zabbix was created by Alexei Vladishev, and currently is actively developed and supported by Zabbix SIA.

Zabbix is an enterprise-class open source distributed monitoring solution.

Zabbix is a software that monitors numerous parameters of a network and the health and integrity of servers, virtual machines, applications, services, databases, websites, the cloud and more. Zabbix uses a flexible notification mechanism that allows users to configure e-mail based alerts for virtually any event. This allows a fast reaction to server problems. Zabbix offers excellent reporting and data visualization features based on the stored data. This makes Zabbix ideal for capacity planning.

Zabbix supports both polling and trapping. All Zabbix reports and statistics, as well as configuration parameters, are accessed through a web-based frontend. A web-based frontend ensures that the status of your network and the health of your servers can be assessed from any location. Properly configured, Zabbix can play an important role in monitoring IT infrastructure. This is equally true for small organizations with a few servers and for large companies with a multitude of servers.

Zabbix is free of cost. Zabbix is written and distributed under the GPL General Public License version 2. It means that its source code is freely distributed and available for the general public.

For the Zabbix web UI to be accessible, we need to allow the below ports through the firewall. 

firewall-cmd --add-service={http,https} --permanent

firewall-cmd --add-port={10051/tcp,10050/tcp} --permanent

firewall-cmd --reload

Install and configure Zabbix for your platform

a. Install Zabbix repository

rpm -Uvh https://repo.zabbix.com/zabbix/6.0/rhel/8/x86_64/zabbix-release-6.0-4.el8.noarch.rpm

dnf clean all

b. Switch DNF module version for PHP
 

dnf module switch-to php:7.4

c. Install Zabbix server, frontend, agent

dnf install zabbix-server-mysql zabbix-web-mysql zabbix-apache-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent -y

Create initial database

Make sure you have database server up and running.

Run the following on your database host.

mysql -u root -p

password

mysql> create database zabbix character set utf8mb4 collate utf8mb4_bin;
mysql> create user zabbix@localhost identified by 'password';
mysql> grant all privileges on zabbix.* to zabbix@localhost;
mysql> set global log_bin_trust_function_creators = 1;
mysql> quit;

On Zabbix server host import initial schema and data. You will be prompted to enter your newly created password.

zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql --default-character-set=utf8mb4 -uzabbix -p zabbix

Disable log_bin_trust_function_creators option after importing database schema.

mysql -uroot -p

password

mysql> set global log_bin_trust_function_creators = 0;
mysql> quit;

e. Configure the database for Zabbix server

Edit file /etc/zabbix/zabbix_server.conf

DBPassword=password

f. Start Zabbix server and agent processes

Start Zabbix server and agent processes and make it start at system boot.

systemctl restart zabbix-server zabbix-agent httpd php-fpm

systemctl enable zabbix-server zabbix-agent httpd php-fpm
