- The latest version of Oracle Java SE Runtime Environment (JRE) 6 or 7. See Installing the JRE.
- Java Native Access (JNA) is required for production installations. See Installing the JNA.
- Python 2.6+ (needed if installing OpsCenter).
- If you are using Ubuntu 10.04 LTS, you must update to JNA 3.4, as described in Installing the JNA using the binary tarball.
- If you are using an older RHEL-based Linux distribution, such as CentOS-5, you may see the following error: GLIBCXX_3.4.9 not found. You must replace the Snappy compression/decompression library (snappy-java-1.0.5.jar) with the snappy-java-220.127.116.11.jar.
The binary tarball runs as a stand-alone process.

By default, Cassandra installs files into the
/var/log/cassandra directories. If you do not have root
access to the default directories, ensure you have write access:
$ 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
The DataStax Community distribution of Cassandra is installed and ready for configuration.
