Before installing Cassandra make sure the following prerequisites are met:

Steps to Install Cassandra

  1. Download the Cassandra DataStax Community tarball:

    $ curl -OL http://downloads.datastax.com/community/dsc.tar.gz
  2. Check which version of Java is installed by running the following command in a terminal window:

    java -version

    Use the latest version of Java 6 on all nodes. Java 7 is not recommended. If you need help installing Java, see Installing the JRE on Debian or Ubuntu Systems.

  3. Unpack the distribution:

    $ tar -xvzf dsc.tar.gz
    $ rm *.tar.gz
  4. By default, Cassandra installs files into the /var/lib/cassandra and /var/log/cassandra directories.

    If you do not have root access to the default directories, ensure you have write access as follows:

    $ sudo mkdir /var/lib/cassandra
    $ sudo mkdir /var/log/cassandra
    $ sudo chown -R $USER:$GROUP /var/lib/cassandra
    $ sudo chown -R $USER:$GROUP /var/log/cassandra
