Install Zabbix with Nginx on Ubuntu 24.04

Install PostgreSQL server

To install Zabbix with Nginx on Ubuntu 24.04, you first need a database, and PostgreSQL is a great choice for storing Zabbix data. This guide shows you how to install the PostgreSQL server package on your Ubuntu system.

For this post, we’re going to be using the PostgreSQL database to use with Zabbix.

Run the command below to install PostgreSQL.

sudo apt update
sudo apt install postgresql postgresql-contrib

After the installation, run the command below to enable PostgreSQL services to start up automatically and check the PostgreSQL service status.

sudo systemctl is-enabled postgresql
sudo systemctl status postgresql

Please read the post below for more information about installing PostgreSQL and using it on Ubuntu.

How to install PostgreSQL on Ubuntu

Install Zabbix packages

Now that PostgreSQL is ready, let’s install the Zabbix packages needed for your Ubuntu 24.04 system, including the necessary components for Nginx support. We’ll start by downloading and adding the official Zabbix repository to your system.

First, download and install the Zabbix repository for Ubuntu by running the command below.

wget https://repo.zabbix.com/zabbix/7.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest+ubuntu24.04_all.deb

Next, run the command below to install the Zabbix repository.

sudo dpkg -i zabbix-release_latest+ubuntu24.04_all.deb

After adding a new repository, you need to refresh your package index (this updates the list of available software) by running the command below.

sudo apt update

Now that the Zabbix repository is set up on your Ubuntu system, you can install the necessary packages with the following command.

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

This command installs several key components:

• Zabbix with PostgreSQL database support
• Zabbix web application or frontend
• PHP and modules, including the ‘pgsql’ module for the PostgreSQL driver
• Nginx and configuration for Zabbix
• Zabbix SQL scripts
• Zabbix agent for monitoring the Zabbix system

Configure Zabbix

With the Zabbix packages installed, it’s time to set up the database Zabbix will use. We’ll create a dedicated PostgreSQL database and a user account specifically for Zabbix to store its monitoring information.

First, create a new database and account to use with Zabbix.

Run the two commands below to create a new PostgreSQL user and database called ‘zabbix‘.

When prompted, create a password for the account.

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

After creating the database and user, run the following command to import the database schema to the database created.

Confirm the password created above.

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

You’ll see a success message if everything works.

Next, run the command below to open Zabbix configuration ‘/etc/zabbix/zabbix_server.conf‘.

sudo nano /etc/zabbix/zabbix_server.conf

Change the default configuration of ‘DBName‘, ‘DBUser‘, and ‘DBPassword‘ with your PostgreSQL database details.

### Option: DBName
# Database Name
# Mandatory: yes
# Default:
# DBName=

DBName=zabbix

### Option: DBUser
#Database user.
# Mandatory: no
# Default:
# DBUser=

DBUser=zabbix

### Option: DBPassword
#Database password.
# Mandatory: no
# Default:
 DBPassword=Type_DBuser_password

Save the file and exit the editor when finished.

Set up Nginx

Now that the Zabbix database is configured, we’ll set up Nginx, the web server that will let you access Zabbix through your browser. This involves opening the Nginx configuration file for Zabbix and making a few key changes.

Run the command below to open the Nginx configuration for Zabbix ‘/etc/zabbix/nginx.conf‘.

sudo nano /etc/zabbix/nginx.conf

Change the highlighted lines to match the ones below.

server {
        listen          8080;
        server_name     zabbix.example.com;

        root    /usr/share/zabbix;

        index   index.php;

............................................

When done, save the file and exit the editor.

Restart Zabbix services

After configuring PostgreSQL and Nginx, you need to restart the Zabbix server, agent, and Nginx services to apply all the changes. This ensures everything is running correctly and ready for Zabbix to start monitoring.

Run the commands below to restart the services.

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

You can check the status when the services are restarted by running the command below.

sudo systemctl status zabbix-server zabbix-agent nginx php8.3-fpm

Access Zabbix

With all Zabbix services running, you can now access the Zabbix web interface from your browser to complete the installation. Simply navigate to your server’s address using the port and hostname we configured earlier.

http://zabbix.example.com:8080

Select the installation language and continue.

Configure the database

Type in the server name and continue.

Zabbix should be installed and ready to use.

Enter the default account below and sign in.

• Username: Admin
• Password zabbix

That should do it!
