In this tutorial, we will show you how to install Apache Cassandra on Debian 11. For those of you who didn’t know, Apache Cassandra is a NoSQL database used for storing large amounts of data. It has a distributed architecture and is designed to manage large volumes of data with dynamic replication. It is used by many large companies like Github, NetFlix, Reddit, and Instagram.
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 through the step-by-step installation of the Cassandra open source NoSQL database on a Debian 11 (Bullseye).

Step 3. Installing Apache Cassandra on Debian 11.

echo "deb https://downloads.apache.org/cassandra/debian 40x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
Next, import the public key of the Cassandra repository:

After that, update the packages’ index and install the Apache Cassandra packages:
sudo apt updatesudo apt install cassandra
Once the installation of Apache Cassandra, its service starts automatically. To verify it, use the command below:
sudo systemctl status cassandra
Also, you can verify the status using the below command:
sudo nodetool status
