How to Install Zabbix with Apache on Ubuntu 24.04

Install PostgreSQL server

Zabbix relies on databases to store its information, and it supports SQL databases like MySQL and PostgreSQL.

For this guide, we’ll use the PostgreSQL database with Zabbix.

Run the command below to install PostgreSQL.

sudo apt update
sudo apt install postgresql postgresql-contrib

After installation, enable PostgreSQL services to start automatically and check their status with the command below.

sudo systemctl is-enabled postgresql
sudo systemctl status postgresql

How to install PostgreSQL on Ubuntu

Install Zabbix packages

With Apache support, you need to install some required packages for Zabbix on Ubuntu.

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

Then, run this command to install the Zabbix repository.

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

After adding the new repository, you’ll need to refresh your package index. Run the command below.

sudo apt update

Once the Zabbix repository is installed on Ubuntu, use the command below to install the necessary packages from it.

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

This command will install the following packages:

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

Configure Zabbix

Now that you have all the necessary Zabbix packages installed, you can configure the Zabbix environment.

First, let’s create a database and account for Zabbix to use.

Run the following two commands to create a new PostgreSQL user and database, which we’ll name ‘zabbix‘.

You’ll be prompted to 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 command below to import the database schema into the database you just created.

Confirm the password you created earlier.

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

You should see a success message if everything went as expected.

Next, open the Zabbix configuration file at ‘/etc/zabbix/zabbix_server.conf’ using the command below.

sudo nano /etc/zabbix/zabbix_server.conf

Update the ‘DBName‘, ‘DBUser‘, and ‘DBPassword‘ settings 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 you’re done.

Restart Zabbix services

PostgreSQL and Apache are now configured and ready. However, you must restart the Zabbix services.

Run the commands below to restart the services.

sudo systemctl restart zabbix-server zabbix-agent apache2
sudo systemctl enable zabbix-server zabbix-agent apache2

You can check the status after restarting the services with the command below.

sudo systemctl status zabbix-server zabbix-agent apache2

Access Zabbix

The Zabbix services should now be configured and running. Open your browser and navigate to your server’s hostname to access the installation wizard.

http://localhost/zabbix

Select your preferred installation language and proceed.

Configure the database

Enter your server name and continue.

Zabbix should now be installed and ready for use.

Enter the default credentials below to sign in.

• Username: Admin
• Password zabbix

That should do it!
