  1. Cassandra is written in Java, so it could be used with different distributions that have correct version of Java (Java 8 - oracle or openjdk). If you're just starting, then you need to take latest released version: 3.11.3 (see this article for full instructions on setup) - add following source:

    deb http://www.apache.org/dist/cassandra/debian 311x main

    and then install cassandra package, plus you need to install Python 2.7 - that's standard python package.

  2. Cassandra distributed database is a snap package in all currently supported versions of Ubuntu. The current stable version of the cassandra snap package is 3.7 and the edge version is 3.10-SNAPSHOT. To install cassandra run this command:

    sudo snap install cassandra   
sudo snap connect cassandra:mount-observe

    The cassandra snap package will be updated automatically when updates are available.

    You can check on the status of the cassandra service with:

    systemctl status snap.cassandra.cassandra.service

    If you were able to successfully start Cassandra, check the status of the cluster:

    cassandra.nodetool status

    In the output, UN means it's Up and Normal:

    Set a custom configuration:

    cat cassandra.yaml | sudo /snap/bin/cassandra.config-set cassandra.yaml

    Commands:

    • cassandra.config-get
    • cassandra.config-set
    • cassandra.env-get
    • cassandra.nodetool
