How to Install Zabbix Monitoring Tool on Ubuntu 22.04

Zabbix is a powerful open-source monitoring solution to monitor IT infrastructure. With Zabbix, you can monitor various IT components, including networks, servers, virtual machines, and cloud services. Zabbix provides a web-based user interface to track and monitor metrics such as network utilization, CPU load, and disk space consumption. You can use these metrics to check the current health of your IT infrastructure and detect problems with hardware or software components. Zabbix offers agent software on the monitored server to gather data and send it to the Zabbix server.

This tutorial will show you how to install the Zabbix monitoring server on Ubuntu 22.04.

Prerequisites

  • A server running Ubuntu 22.04.
  • A root password is configured on the server.

Install Zabbix Repository

The Zabbix package is not available in the Ubuntu 22.04 default repository. So you will need to download and install the Zabbix official repository on your server.

First, download the Zabbix 6 repository package from their official website using the following command:
wget https://repo.zabbix.com/zabbix/6.2/ubuntu/pool/main/z/zabbix-release/zabbix-release_6.2-4%2Bubuntu22.04_all.deb

Next, install it using the following command:
dpkg -i zabbix-release_6.2-4+ubuntu22.04_all.deb

Once the Zabbix repository is added to APT, you can proceed to install the Zabbix server.

Install Zabbix Monitoring Server

First, update the Zabbix repository using the following command:
apt-get update -y

Next, install the Zabbix server including other required components using the following command:
apt-get install zabbix-server-mysql zabbix-frontend-php zabbix-apache-conf zabbix-sql-scripts zabbix-agent zabbix-frontend-php zabbix-apache-conf -y

After installing all packages, edit the PHP configuration file and set your timezone:
nano /etc/php/8.1/apache2/php.ini

Change the following line:
date.timezone = UTC

Save and close the file when you are finished.

Configure MariaDB Database

Zabbix uses a MariaDB as a database backend. You can install the MariaDB database server by running the following command:
apt-get install mariadb-server -y

Once the MariaDB server is installed, secure the MariaDB installation and set the root password with the following command:
mariadb-secure-installation

Answer all the questions as shown below:
Enter current password for root (enter for none):
Switch to unix_socket authentication [Y/n] n
Remove anonymous users? [Y/n] y
Disallow root login remotely? [Y/n] y
Remove test database and access to it? [Y/n] y
Reload privilege tables now? [Y/n] y

Next, connect to the MariaDB shell using the following command:
mysql -u root -p

Once you are logged in, create a database and user for Zabbix with the following command:
MariaDB [(none)]> CREATE DATABASE zabbix character set utf8mb4 collate utf8mb4_bin;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON zabbix.* TO zabbix@localhost IDENTIFIED BY 'password';

Next, flush the privileges and exit from the MariaDB with the following command:
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT;

Once you are finished, you can proceed to the next step.

Configure Zabbix Server

Next, edit the Zabbix configuration file and define your database with the following file:
nano /etc/zabbix/zabbix_server.conf

Change the following lines:
DBName=zabbix
DBUser=zabbix
DBPassword=password

Save and close the file when you are finished. Next, import the Zabbix data with the following command:
zcat /usr/share/zabbix-sql-scripts/mysql/server.sql.gz | mysql -u zabbix -p zabbix

Finally, restart and enable all the services using the following command:
systemctl restart apache2
systemctl enable zabbix-server zabbix-agent apache2
systemctl restart zabbix-server zabbix-agent

You can now check the Zabbix server status using the following command:
systemctl status zabbix-server

You will get the following output:
