How To Install Apache Cassandra on Debian 10

In this tutorial, we will show you how to install Apache Cassandra on Debian 10. For those of you who didn’t know, Apache Cassandra is a NoSQL database intended for storing large amounts of data in a decentralized, highly available cluster. NoSQL refers to a database with a data model other than the tabular relations used in relational databases such as MySQL, PostgreSQL, and Microsoft SQL. The Apache Cassandra database is the right choice when you need scalability and high availability without compromising performance.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of Apache Cassandra NoSql on a Debian 10 (Buster) server.

Prerequisites

• A server running one of the following operating systems: Debian 10 (Buster).
• It’s recommended that you use a fresh OS install to prevent any potential issues.
• SSH access to the server (or just open Terminal if you’re on a desktop).
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Apache Cassandra on Debian 10 Buster

Step 1. Before we install any software, it’s important to make sure your system is up to date by running the following apt commands in the terminal:

sudo apt update
sudo apt upgrade
sudo apt install apt-transport-https ca-certificates wget dirmngr gnupg software-properties-common

Step 2. Installing OpenJDK.

Now, we import the repository’s GPG key and add the AdoptOpenJDK APT repository to your system:

wget -qO - https://adoptopenjdk.jfrog.io/adoptopenjdk/api/gpg/key/public | sudo apt-key add -
sudo add-apt-repository --yes https://adoptopenjdk.jfrog.io/adoptopenjdk/deb/

Then, you will need to fully update the system with the following command and install it:

sudo apt update
sudo apt install adoptopenjdk-8-hotspot

Step 3. Installing Apache Cassandra on Debian 10.

First, import the repository public key using the following wget command:

wget -q -O - https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add -

Next, add the Cassandra repository to your system sources’ list by running the command:

sudo sh -c 'echo "deb https://www.apache.org/dist/cassandra/debian 311x main" > /etc/apt/sources.list.d/cassandra.list'

Then, install the Apache Cassandra package using the following command:

sudo apt update
sudo apt install cassandra

Cassandra’s service will automatically start after the installation process is complete. You can verify that Cassandra is running by typing:

nodetool status

Congratulations! You have successfully installed Apache Cassandra. Thanks for using this tutorial for installing the latest version of Apache Cassandra on the Debian 10 Buster system. For additional help or useful information, we recommend you to check the official Apache Cassandra website.
