How to Install and Configure Zabbix on Rocky Linux

Zabbix is a powerful open-source monitoring solution that provides real-time monitoring of servers, network devices, and applications. In this comprehensive guide, we will walk you through the process of how to install and configure Zabbix on Rocky Linux, an enterprise-grade Linux distribution.

How to Install and Configure Zabbix on Rocky Linux

Prerequisites

Before we begin, ensure that you have the following:

• A Rocky Linux server with root access
• LAMP stack installed (Apache, MySQL/MariaDB, PHP)
• A valid domain name configured to point to your server

Install and Configure MySQL/MariaDB on Rocky Linux

First, we need to install a database server to store Zabbix data. You can choose between MySQL or MariaDB. For this tutorial, we will use MariaDB. If you haven’t installed it yet, follow our guide on how to install MariaDB on Rocky Linux.

Once installed, create a new database and user for Zabbix:

mysql -u root -p
CREATE DATABASE zabbix_db;
GRANT ALL PRIVILEGES ON zabbix_db.* TO 'zabbix_user'@'localhost' IDENTIFIED BY 'your_password';
FLUSH PRIVILEGES;
EXIT;

Replace your_password with a strong password.

Install Zabbix Server on Rocky Linux

To install Zabbix, we need to add the Zabbix repository and install the required packages:

rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/8/x86_64/zabbix-release-5.0-1.el8.noarch.rpm
dnf clean all
dnf -y install zabbix-server-mysql zabbix-web-mysql zabbix-agent zabbix-apache-conf

Import Zabbix Database Schema on Rocky Linux

Next, import the Zabbix database schema using the following commands:

zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -u zabbix_user -p zabbix_db

Enter the password for the zabbix_user when prompted.

Configure Zabbix Server on Rocky Linux

Edit the Zabbix server configuration file /etc/zabbix/zabbix_server.conf:

nano /etc/zabbix/zabbix_server.conf

Update the following lines with your database details:

DBName=zabbix_db
DBUser=zabbix_user
DBPassword=your_password

Save and exit the file.

Configure PHP for Zabbix Web Interface

Edit the Zabbix Apache configuration file /etc/httpd/conf.d/zabbix.conf:

nano /etc/httpd/conf.d/zabbix.conf

Find the following lines and update the timezone:

php_value[date.timezone] = your_timezone

Replace your_timezone with your preferred timezone, e.g., America/New_York. You can find a list of supported timezones here.

Save and exit the file.

Start and Enable Zabbix Services on Linux

Enable and start Zabbix server, agent, and Apache services:

systemctl enable zabbix-server zabbix-agent httpd
systemctl start zabbix-server zabbix-agent httpd

Configure Firewall on Rocky Linux

Allow incoming connections to the Zabbix web interface and agent:

firewall-cmd --add-service={http,https} --permanent
firewall-cmd --add-port=10050/tcp --permanent
firewall-cmd --reload

Configure Zabbix Frontend

Access the Zabbix frontend by opening your favorite web browser and navigating to:

http://your_server_ip/zabbix

You’ll be greeted with the Zabbix welcome screen. Click Next step to proceed.

• Check prerequisites: The Zabbix installation will check if all prerequisites are met. If there are no issues, click Next step.
• Configure DB connection: Enter the database information you set up earlier:
  • Database type: MySQL
  • Database host: localhost
  • Database port: 3306 (default)
  • Database name: zabbix
  • User: zabbix
  • Password: your_password_here
  • Click Next step.
• Zabbix server details: Enter your server details:
  • Name: Zabbix Server (or any name you prefer)
  • Host: localhost
  • Port: 10051 (default)
  • Click Next step.
• Pre-installation summary: Review the pre-installation summary and click Next step if everything is correct.
• Install: Click Finish to complete the installation.

Log in to Zabbix

After the installation is complete, you’ll be redirected to the Zabbix login page. The default username and password are:

• Username: Admin
• Password: zabbix

You are now logged into your Zabbix server. Take some time to explore the features and settings available to you.
