• A server running AlmaLinux 10
• MySQL or MariaDB installed and configured

Update the System

First, update the system packages to ensure everything is up-to-date:

dnf update -y

Install and Configure MariaDB

---

Install MariaDB server,

yum install mariadb-server mariadb -y

Start and enable MariaDB.

systemctl start mariadb
systemctl enable mariadb
systemctl status mariadb

Secure the installation (set root password, remove anonymous users, disallow remote root login, etc.):

mysql_secure_installation

Install Zabbix

Disable Zabbix packages provided by EPEL: Edit /etc/yum.repos.d/epel.repo and add the following line under the [epel] section:

excludepkgs=zabbix*

Install the official Zabbix repository,

rpm -Uvh https://repo.zabbix.com/zabbix/7.2/release/alma/9/noarch/zabbix-release-latest-7.2.el9.noarch.rpm
dnf clean all

Install Zabbix Server, Frontend, and Agent,

dnf install zabbix-server-mysql zabbix-web-mysql zabbix-nginx-conf zabbix-sql-scripts zabbix-selinux-policy zabbix-agent glibc-langpack-en -y

Configure MariaDB for Zabbix

---

Create the Zabbix database and user,

mysql -uroot -p

Run the following SQL commands,

CREATE DATABASE zabbix CHARACTER SET utf8mb4 COLLATE utf8mb4_bin;
CREATE USER 'zabbix'@'localhost' IDENTIFIED BY 'Your_Password_Here';
GRANT ALL PRIVILEGES ON zabbix.* TO 'zabbix'@'localhost';
SET GLOBAL log_bin_trust_function_creators = 1;
QUIT;

Note: Replace Your_Password_Here with actual strong password

Import the initial schema and data,

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

Disable the log_bin_trust_function_creators option after importing:

mysql -uroot -p

Run,

SET GLOBAL log_bin_trust_function_creators = 0;
QUIT;

Start the Zabbix server, agent, and other required services,

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

Enable them to start on boot,

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

Configure the Firewall

---

Allow traffic on port 8080 for the Zabbix frontend:
