In this tutorial, we will explain how to install and configure Zabbix on Ubuntu 24.04. We will use PostgreSQL as the database backend and Nginx as the web server and secure with Let's Encrypt SSL certificate.

Zabbix is an open-source network monitoring and management solution designed to monitor the performance and availability of networks, servers, applications, and services. With its robust feature set, Zabbix offers real-time monitoring, alerting, and visualization of metrics, providing insights into the health and performance of IT infrastructure.

It supports various data gathering methods, including agent-based and agentless monitoring, SNMP, IPMI, and custom scripts, making it highly adaptable to diverse environments. 

Install and Configure Zabbix on Ubuntu


Before starting, ensure you have:

  • A fresh installation of Ubuntu 24.04 dedicated server and KVM VPS with sudo privileges.
  • A static IP address configured on your server.

Step 1: Update Your System

Begin by updating your package list and upgrading the installed packages:

sudo apt update
sudo apt upgrade -y

Step 2: Install PostgreSQL

Install PostgreSQL, which will be used as the database for Zabbix:

sudo apt install postgresql postgresql-contrib -y

After installation, create a PostgreSQL user and database for Zabbix:

sudo -u postgres psql

Within the PostgreSQL shell, execute the following commands:

CREATE USER zabbix WITH PASSWORD 'your_password';

Replace your_password with a strong password for the Zabbix database user.

Step 3: Install Nginx

Install Nginx to serve the Zabbix web interface:

sudo apt install nginx -y

Start and enable Nginx to start at boot:

sudo systemctl start nginx
sudo systemctl enable nginx

Step 4: Install Zabbix Server, Web Frontend, and Agent

Install the Zabbix repository configuration package:

sudo dpkg -i zabbix-release_6.0-6+ubuntu24.04_all.deb
sudo apt update

Install the Zabbix server, web frontend, and agent:

sudo apt install zabbix-server-pgsql zabbix-frontend-php php8.3-pgsql zabbix-nginx-conf zabbix-sql-scripts zabbix-agent -y

Step 5: Configure PostgreSQL for Zabbix

Import the initial schema and data for Zabbix:

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

Now, let's configure Zabbix Server. Edit the Zabbix server configuration file to use PostgreSQL:

sudo nano /etc/zabbix/zabbix_server.conf

Update the following parameters:


Save and close the file.

Step 6: Configure PHP for Zabbix Frontend

Edit the PHP configuration file for Zabbix:

sudo nano /etc/zabbix/nginx.conf

Modify the listen and server_name directives to match your server's configuration. Ensure the following settings are correctly configured:

server {
    listen 80;

Note: Replace with your domain name

Save and close the file.

Start and enable the Zabbix server and agent to start at boot:

sudo systemctl start zabbix-server zabbix-agent nginx php8.3-fpm
sudo systemctl enable zabbix-server zabbix-agent nginx php8.3-fpm

Step 7: Secure with SSL

Certbot is a tool for automatically obtaining and renewing SSL certificates from Let's Encrypt. Install Certbot and the Nginx plugin:

sudo apt install certbot python3-certbot-nginx -y

Use Certbot to obtain a certificate for your domain. Replace with your actual domain name:

sudo certbot --nginx -d

Follow the prompts to choose the appropriate domain(s) and agree to the terms of service. Certbot will automatically configure Nginx to use the obtained certificate.

If you have a firewall enabled on your server, allow HTTPS traffic (port 443):

sudo ufw allow http
sudo ufw allow https
sudo ufw reload

Step 8: Configure Zabbix Frontend

Open a web browser and navigate to Follow the on-screen instructions to complete the Zabbix installation:

  • Select your language and click "Next".
  • Check for pre-requisites and click "Next".
  • Configure the database connection:
  • Database type: PostgreSQL
  • Database host: localhost
  • Database name: zabbix
  • User: zabbix
  • Password: your_password

Continue with the installation steps, setting up the server details and finishing the setup.

Step 9: Log In to Zabbix

Once the setup is complete, log in to the Zabbix frontend with the default credentials:

Username: Admin
Password: zabbix


We have seen how to install and configure Zabbix on Ubuntu 24.04 using PostgreSQL and Nginx and secured with Let's Encrypt SSL certificate. You can now use Zabbix to monitor your network performance and availability. Make sure to secure your Zabbix installation by changing default passwords and configuring proper firewall rules.
