Installing DataStax Community on RHEL-based systems

Install using Yum repositories on RHEL, CentOS, and Oracle Linux.

DataStax no longer provides the DataStax Community version of Apache Cassandra™ or the DataStax Distribution of Apache Cassandra. See DataStax support for Apache Cassandra.
To download and install the latest version of open-source Cassandra, see https://cassandra.apache.org/.

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 Apache Cassandra.

Prerequisites

  • Yum Package Management application installed.
  • Root or sudo access to the install machine.
  • Latest version of Oracle Java Platform, Standard Edition 8 (JDK) or OpenJDK 7.
    Note: The JDK is recommended for development and production systems. It provides tools that are not in the JRE, such as jstack, jmap, jps, and jstat, that are useful for troubleshooting.
  • Python 2.7.

The packaged releases create a cassandra user. When starting Cassandra as a service, the service runs as this user. The following utilities are included in a separate package: sstable2json, sstablelevelreset, sstablemetadata, json2sstable, sstablerepairedset, sstablesplit, and token-generator.

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 or OpenJDK 7 on all nodes.
  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 dsc22
$ sudo yum install cassandra22-tools ## Installs optional utilities.
    Note: The optional utilities are json2sstable, sstable2json, sstablelevelreset, sstablemetadata, sstableofflinerelevel, sstablerepairedset, sstablesplit, token-generator. Each utility provides usage/help information; type help after entering the command.

    The DataStax Community distribution of Cassandra is ready for configuration.
