This brief tutorial shows students and new users how to install Apache Cassandra on Ubuntu 20.04 | 18.04.

Apache Cassandra is a free and open-source, distributed NoSQL database system with high availability across multiple systems thus eliminating a single failure point.

If you need a database management system with scalability and high availability, you may want to look at Apache Cassandra.

This database platform is used small and large companies who process massive amount of data… Data is automatically replicated to multiple nodes for fault-tolerance… with no single points of failure…

This brief tutorial shows students and new users how to install Apache Cassandra on Ubuntu 16.04 | 18.04 LTS servers.

For more about Apache Cassandra, please visit its homepage.

If you want to test it in your lab environment before going out and using it in production, the steps below should be a great place to start.

Follow the steps below to get Apache Cassandra installed on Ubuntu

Step 1: Install JAVA

To get the latest version of Apache Cassandra, you can either use its .DEB file from its website or add its official repository to Ubuntu… However, you are going to need Oracle JAVA installed on the system for Cassandra to work.

The open source version of Oracle JAVA works great with Cassandra, so for this tutorial, we’re going to be using OpenJDK 8…

To install OpenJDK 8, run the commands below:

sudo apt update
sudo apt install openjdk-8-jdk

To verify if OpenJDK is installed and running, run the commands below:

java -version

It should print out the lines similar to the ones below:

openjdk version "1.8.0_191"
OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.18.04.1-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

After installing OpenJDK 8, continue below to installing Apache Cassandra.
