How to Set Up Zabbix Monitoring from Scratch

Zabbix is one of the most popular open-source monitoring solutions used by IT teams worldwide. In this tutorial, you'll learn how to install Zabbix, add your first hosts, and set up alerts.

Prerequisites

• A Linux server (Ubuntu 22.04 or later recommended)
• Root or sudo access
• Basic command line knowledge

Step 1: Install Zabbix Repository

First, download and install the Zabbix repository package:

wget https://repo.zabbix.com/zabbix/6.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.4-1+ubuntu22.04_all.deb
sudo dpkg -i zabbix-release_6.4-1+ubuntu22.04_all.deb
sudo apt update

Step 2: Install Zabbix Server and Frontend

sudo apt install zabbix-server-pgsql zabbix-frontend-php php8.1-pgsql zabbix-nginx-conf zabbix-sql-scripts zabbix-agent

Step 3: Configure the Database

Create a PostgreSQL database for Zabbix:

sudo -u postgres createuser --pwprompt zabbix
sudo -u postgres createdb -O zabbix zabbix

Import the initial schema:

zcat /usr/share/zabbix-sql-scripts/postgresql/server.sql.gz | sudo -u zabbix psql zabbix

Step 4: Configure Zabbix Server

Edit the Zabbix server configuration:

sudo nano /etc/zabbix/zabbix_server.conf

Set the database password:

DBPassword=your_password_here

Step 5: Start Zabbix

sudo systemctl restart zabbix-server zabbix-agent nginx php8.1-fpm
sudo systemctl enable zabbix-server zabbix-agent nginx php8.1-fpm

Step 6: Access the Web Interface

Open your browser and navigate to http://your-server-ip/zabbix. Follow the setup wizard:

1. Check prerequisites — all should be green
2. Enter your database credentials
3. Set the server name
4. Default login: Admin / zabbix

Step 7: Add Your First Host

1. Go to Configuration > Hosts > Create Host
2. Enter the hostname and IP address
3. Link a template (e.g., "Linux by Zabbix agent")
4. Click Add

Step 8: Set Up Email Alerts

1. Go to Administration > Media Types
2. Configure your email settings (SMTP server, port, credentials)
3. Go to your user profile and add the email as a media
4. Create an action under Configuration > Actions to trigger on problems

Conclusion

You now have a working Zabbix installation monitoring your first host. From here you can add more hosts, create custom dashboards, and fine-tune your alerting. Check out the Zabbix documentation for advanced features like auto-discovery and API integration.
