How to Install Zabbix with Apache on Ubuntu 24.04

Install PostgreSQL server

To install PostgreSQL server on Ubuntu 24.04 for your monitoring database, open your terminal and run the command sudo apt install postgresql postgresql-contrib. This sets up the database backend required to store all your metrics and system data. PostgreSQL services start automatically after installation so you can move straight on to setting up your software packages.

PostgreSQL serves as the primary database backend for this deployment.

Execute the command below to install PostgreSQL.

PostgreSQL services start automatically after installation to ensure continuous monitoring. Check the PostgreSQL service status using the command `sudo systemctl status postgresql`.

sudo systemctl is-enabled postgresql
sudo systemctl status postgresql

Consult the following resource for additional details regarding PostgreSQL configuration on Ubuntu.

How to install PostgreSQL on Ubuntu

Install Zabbix packages

To install Zabbix packages on Ubuntu 24.04, you first need to add the official software repository to your system. Download the repository package by running wget https://repo.zabbix.com/zabbix/7.0/ubuntu/pool/main/z/zabbix-release/zabbix-release_latest+ubuntu24.04_all.deb in your terminal, and then process the installation using sudo dpkg -i zabbix-release_latest+ubuntu24.04_all.deb to prepare for the main software setup.

Fetch and install the Zabbix repository for Ubuntu by executing the command below.

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

Process the Zabbix repository installation by running this command.

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

Refreshing the local package index is necessary after adding a new repository. Execute the command below.

Execute `sudo apt install zabbix-server-mysql zabbix-frontend-php zabbix-agent` to install the Zabbix server, frontend, and agent packages from the repository.

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

This command installs 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

To configure Zabbix with your PostgreSQL database, you must create a dedicated database and user account to store your monitoring data securely. Run the required PostgreSQL administrative commands to create a new user and a database named zabbix protected by a secure password, which allows the monitoring software to communicate with your server backend.

Initialize the database and credentials for Zabbix.

Two specific commands establish the new PostgreSQL user and database named 'zabbix', which provides persistent storage for monitoring metrics.

Terminal prompts request a secure password for the account.

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

Import the database schema into the newly created database by running the command below.

Provide the previously generated password when prompted.

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

A success message appears if the import completes without errors.

Open the Zabbix server configuration file located at /etc/zabbix/zabbix_server.conf using a command-line text editor. This file controls server operations, including database credentials and network port assignments.

sudo nano /etc/zabbix/zabbix_server.conf

Update the 'DBName', 'DBUser', and 'DBPassword' settings with the PostgreSQL database credentials.

### 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 changes and exit the text editor.

Restart Zabbix services

To restart Zabbix services and apply your new configuration on Ubuntu 24.04, run systemctl restart zabbix-server zabbix-agent apache2 in your terminal. Follow this by running systemctl enable zabbix-server zabbix-agent apache2 to configure the Zabbix server, Zabbix agent, and Apache web server to launch automatically whenever your computer boots up.

Execute the commands below to restart the services.

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

Verify service operational status using the command below.

sudo systemctl status zabbix-server zabbix-agent apache2

Access Zabbix

To access Zabbix after installation, open your web browser and go to http://localhost/zabbix to load the setup wizard. The interface walks you through selecting your preferred installation language, entering your database connection parameters, and naming your server so you can finish setting up your monitoring dashboard.

http://localhost/zabbix

Select the preferred installation language and proceed.

Configure the database

Input the server name and continue.

Zabbix is now fully installed and operational.

Provide the default credentials below to authenticate.

• Username: Admin
• Password zabbix

Deployment is complete.
