In this tutorial, we will show you how to install Apache Cassandra on Ubuntu 18.04 LTS. 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 through the step by step installation Apache Cassandra on a Ubuntu 18.04 (Bionic Beaver) server.
Install Apache Cassandra on Ubuntu 18.04 LTS Bionic Beaver
Step 1. First, make sure that all your system packages are up-to-date by running these following apt commands in the terminal.
1 2 3 | sudoaptupdate sudoaptupgrade sudoaptinstallapt-transport-https |
Install the Java package by typing:
1 | sudoaptinstallopenjdk-8-jdk |
Verify Installed Java Version:

Import the repository’s GPG using the following wget command:
1 | wget-q-O-https://www.apache.org/dist/cassandra/KEYS | sudo apt-key add - |
Next, add the Cassandra repository to the system:
1 | sudosh-c'echo "deb http://www.apache.org/dist/cassandra/debian 311x main" > /etc/apt/sources.list.d/cassandra.list' |
Once the repository is enabled, update the apt package list and install the latest version of Apache Cassandra by typing:
1 2 | sudoaptupdate sudoaptinstallcassandra |
Cassandra service will automatically start after the installation process is complete. You can verify that Cassandra is running by typing:
