Instructions for installing DataStax Enterprise (DSE) 6.0 on RHEL-based systems using Yum.

To install on SUSE, use the binary tarball installation.

Some things to know about installing DSE

  • The latest version of DataStax Enterprise 6.0 is 6.0.6.
  • When installed from a package (Yum or APT), DataStax Enterprise runs as a service. The service initialization script is located in /etc/init.d/dse. Run levels are not set by the package.
  • This procedure installs DSE 6.0 and the DataStax Agent. It does not install OpsCenter, DataStax Studio, Graph Loader, or DataStax Bulk Loader.
  • When connecting to DSE 6.0 from OpsCenter, use version OpsCenter 6.5; earlier versions are not supported. See DataStax OpsCenter compatibility with DSE.
Warning: When DSE is installed, it creates a cassandra user in the database. Do not use the cassandra user in production. Failing to do so is a security risk. See Adding a superuser login.

In a terminal window:

  1. Verify that a required version of Java is installed:
    java -version
    If OpenJDK, the results should look like:
    openjdk version "1.8.0_171"
    OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.16.04.1-b11)
    OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)
    If Oracle Java, the results should look like:
    java version "1.8.0_181"
    Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
    Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

    If not OpenJDK 8 or Oracle Java 8, see Installing supporting software on DataStax Enterprise 6.0.

  2. Install the libaio package. For example:
    sudo yum install libaio
  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 downloads_key are your DataStax Academy email address and My Downloads Key. 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 \|.

    For backward compatibility, you can use your DataStax Academy Profile Name and password instead of your email address and Downloads Key.

  4. If you have enabled signature verification (gpgcheck=1), import the DataStax Enterprise repository key:
    sudo rpm --import 
  5. Install the DataStax Enterprise package:
    • Install the latest version (6.0.6):
      sudo yum install dse-full-6.0.6-1
    • Install an earlier 6.0.x version:
      Note: To view the available 6.0.x versions, see the Release notes.
      sudo yum install dse-full-version_number-1
      For example:
      sudo yum install dse-full-6.0.0-1
    • Optional: Install the demos:
      Attention: Installing the DSE demos is not recommended for production. Only install the demos in development environments to run tutorials.
      sudo yum install dse-demos-6.0.6-1
    DataStax Enterprise is ready for additional configuration. See What's next.
  6. Optional: Single-node cluster installations only:
    1. Start DataStax Enterprise:
      sudo service dse start

      For more start options, see Starting DataStax Enterprise as a service.

    2. Verify that DataStax Enterprise is running:
      nodetool status
