Installing DataStax Enterprise 4.7 using Yum repositories 

Install DataStax Enterprise, DataStax Agent, and OpsCenter using Yum repositories on RHEL-based systems.

Note: To install on SUSE, use the GUI installer or the binary tarball installation.

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

Important: DataStax Enterprise 4.7 uses Cassandra 2.1.


  • DataStax Academy registration email address and password.
  • Yum Package Management application.
  • Root or sudo access to the install machine.
  • Latest version of Oracle Java SE Runtime Environment 7 or 8 or OpenJDK 7 is recommended.
    Note: If using Oracle Java 7, you must use at least 1.7.0_25. If using Oracle Java 8, you must use at least 1.8.0_40. In some cases, using JDK 1.8 causes minor performance degradation compared to JDK 1.7.
  • RedHat-compatible distributions require EPEL (Extra Packages for Enterprise Linux). For RHEL 5.x, see Installing EPEL on RHEL OS 5.x.
  • If installing on a 64-bit Oracle Linux distribution, first install the 32-bit versions of glibc libraries.
  • Python 2.6 (minimum); 2.7 (recommended).

Note: JNA (Java Native Access) is automatically installed.

The packaged releases create a cassandra user. When starting DataStax Enterprise as a service, the Cassandra and Hadoop tracker services run as this user. The service initialization script is located in /etc/init.d/dse. Run levels are not set by the package.


These steps install DataStax Enterprise, the DataStax Agent, and OpsCenter (optional). After installing, you must configure and start DataStax Enterprise.

In a terminal window:

Note: In the following commands, be sure to change X to an actual version number. To view the available versions, see the Release notes. The latest version of DataStax Enterprise 4.7 is 4.7.9.

  1. Verify that a required version of Java is installed:
    $ java -version

    If not Oracle Java 7, Oracle Java 8, or OpenJDK 7, see Installing Oracle JDK or the OpenJDK documentation.

    Important: Package management tools do not install Oracle Java.
  2. Make sure that the EPEL is installed. See Installing EPEL on RHEL OS 5.x.
  3. Add the DataStax Yum repository to a file called /etc/yum.repos.d/datastax.repo.
    Note: Set the gpgcheck=1 to perform a GPG signature check.
    name = DataStax Repo for DataStax Enterprise
    where dsa_email_address and password are the DataStax Academy account credentials you created on the registration page.
    Note: Be sure to use your registration email address, not your username.
  4. If you have enabled signature verification (gpgcheck=1), import the DataStax Enterprise repository key:
    $ rpm --import 
  5. Install the package:
    $ sudo yum install dse-full-4.7.X-1 (Use for all product levels.)

    For production installations, DataStax recommends installing the OpsCenter separate from the cluster. See the OpsCenter documentation.

    Attention: Depending on your environment, you might need to replace @ in your email address with %40 and escape any character in your password that is used in your operating system's command line. Examples: \! and \|.
  6. Optional: Review the installation logs to verify the installation.
