Use these steps to install Cassandra using Yum repositories on RHEL, CentOS, and Oracle Linux.

Note: To install on SUSE, use the Cassandra binary tarball distribution.

For a complete list of supported platforms, see DataStax Community – Supported Platforms.

Prerequisites

  • Yum Package Management application installed.
  • Root or sudo access to the install machine.
  • Latest version of Oracle Java SE Runtime Environment (JRE) 8 (recommended) or OpenJDK 7.
  • Python 2.6+ (needed if installing OpsCenter).
  • Java Native Access (JNA) is required for production installations (latest version recommended). See Installing the JNA on RHEL or CentOS Systems.

The packaged releases create a cassandra user. When starting Cassandra as a service, the service runs as this user.

Procedure

In a terminal window:

  1. Check which version of Java is installed by running the following command:
    $ java -version
    It is recommended to use the latest version of Oracle Java 8 on all nodes. (Oracle Java 7 is also supported.)

    See Installing Oracle JRE on RHEL-based Systems.

  2. Add the DataStax Community repository to the /etc/yum.repos.d/datastax.repo:
    [datastax] 
    name = DataStax Repo for Apache Cassandra
    baseurl = http://rpm.datastax.com/community
    enabled = 1
    gpgcheck = 0
  3. Install the packages:
    $ sudo yum install dsc20-2.0.x-1 cassandra2.0.x-1
    For example, to install DataStax Community 2.0.11:
    $ sudo yum install dsc20-2.0.11-1 cassandra20-2.0.11-1

    Check Download DataStax Community Edition on Planet Cassandra for the latest version.

    The DataStax Community distribution of Cassandra is ready for configuration.
