How to Install Zabbix with Apache on Ubuntu 24.04

Install PostgreSQL server

Installing 💿 Zabbix on Ubuntu 24.04 requires a PostgreSQL database (an open-source relational database management system) to store monitoring metrics. Run `sudo apt install postgresql postgresql-contrib` to install the PostgreSQL database server and management tools.

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

Deploying the Zabbix software and Apache web server follows database preparation. Downloading and installing the official Zabbix repository on Ubuntu makes the required installation packages accessible.

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

Configuring database connectivity comes next after deploying the Zabbix software. Establishing this connection involves creating a dedicated database and user account. PostgreSQL commands generate a new user and database named 'zabbix' protected by a secure password.

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

Restarting the Zabbix server, Zabbix agent, and Apache web server services on Ubuntu 24.04 applies the new configuration. Running `systemctl restart zabbix-server zabbix-agent apache2` reloads the services, while `systemctl enable zabbix-server zabbix-agent apache2` configures them to launch automatically at boot.

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

Open a web browser and navigate to `http://localhost/zabbix` to load the setup wizard. The interface walks administrators through language selection, database connection parameters, and server naming.

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.
