Step 2. Add the GPG Key

To avoid issues with the repository, add the GPG key and increase the security of the repository. First, install wget if it’s not present on the system:

sudo apt install wget

Then, add the primary key with the following command:

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

Step 3. Add the Cassandra Repository File

Add the Cassandra repository to the system’s repository file. To do that, type the following command in the command line:

echo "deb http://www.apache.org/dist/cassandra/debian 40x main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list deb http://www.apache.org/dist/cassandra/debian 40x main

Step 4. Install Cassandra on Ubuntu

Refresh the repositories and then proceed to install Cassandra on Ubuntu:

sudo apt-get update

sudo apt install cassandra -y

Step 5. Enable and Start Cassandra

At the end of the installation, enable the Cassandra service to start automatically when the system boots. In addition, start it manually for the first time with the following commands:

sudo systemctl enable cassandra

sudo systemctl start cassandra

Step 6. Verify the Installation

To check if the installation has been successful, check the status of the service. To do this, run the following command:

sudo systemctl status cassandra
