How to Install Zabbix on POP! OS

Zabbix is an open source monitoring software that can monitor various aspects of your IT infrastructure. In this tutorial, we will guide you through the installation of Zabbix on POP! OS, the latest version of the popular Linux distribution.

Prerequisites

Before you begin, make sure you have:

• A running instance of POP! OS with root access.
• A terminal emulator installed on your system.

Step 1: Update System

Update your system packages to the latest version using the following commands:

sudo apt update && sudo apt upgrade

Step 2: Install Required Dependencies

Install the following dependencies required by Zabbix using the command below:

sudo apt install build-essential libcurl4-gnutls-dev libopenjp2-7-dev libpng-dev libssl-dev libxml2-dev libsnmp-dev libevent-dev libldap2-dev libz-dev libpcre3-dev

Step 3: Install PostgreSQL Database

Zabbix requires a database to store its data. In this tutorial, we will install PostgreSQL as the database engine.

Install PostgreSQL using the following command:

sudo apt install postgresql postgresql-contrib

Step 4: Configure PostgreSQL Database

By default, PostgreSQL installs with a single user "postgres" and no password. We'll need to set a password for the "postgres" user.

Change the "postgres" user password using the following command:

sudo su - postgres
psql -c "ALTER USER postgres WITH PASSWORD 'your-secret-password';"
exit

Step 5: Create Zabbix Database

Create a new database user and a new database specifically for Zabbix by executing the following commands in order:

sudo su - postgres
createuser zabbix
createdb -O zabbix zabbix

Step 6: Install Zabbix Server and Agent

Add the Zabbix repository to apt sources using the following command:

sudo wget https://repo.zabbix.com/zabbix/5.4/ubuntu/pool/main/z/zabbix-release/zabbix-release_5.4-1+ubuntu$(lsb_release -rs)_all.deb
sudo dpkg -i zabbix-release_5.4-1+ubuntu$(lsb_release -rs)_all.deb
sudo apt update

Install the Zabbix server and agent using the following command:

sudo apt install zabbix-server-pgsql zabbix-frontend-php zabbix-apache-conf zabbix-agent

Step 7: Configure Zabbix Server and Agent

Edit the Zabbix server configuration file /etc/zabbix/zabbix_server.conf and add the following lines at the end of the file:

DBName=zabbix
DBUser=zabbix
DBPassword=your-secret-password

Edit the Zabbix agent configuration file /etc/zabbix/zabbix_agentd.conf and add the following line to allow the agent to communicate with the server:

Server=<ZABBIX_SERVER_IP_ADDRESS>

Note: Replace <ZABBIX_SERVER_IP_ADDRESS> with the IP address of your Zabbix server.

Step 8: Restart Zabbix Services

Restart the Zabbix services to apply the configuration changes:

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

Step 9: Access Zabbix Web Interface

Zabbix web interface is now available at http://your-ip/zabbix. Open your web browser and navigate to the URL.

Use the default credentials Admin and zabbix to log in to the dashboard.

Conclusion

In this tutorial, you learned how to install Zabbix on POP! OS, configure PostgreSQL as the database engine, and start monitoring your IT infrastructure using the Zabbix web interface.
