Installing DataStax Enterprise 6.9 on Debian-based systems using APT

Use these instructions for installing DataStax Enterprise (DSE) 6.9 on Debian-based systems using APT.

Some things to know about installing DataStax Enterprise:

  • These instructions apply to all versions of DataStax Enterprise 6.9. For specific changes please see the DSE 6.9 release notes.

  • 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 6.9 and the DataStax Agent. It does not install OpsCenter, DataStax Studio, or DataStax Bulk Loader.

  • When connecting to DSE 6.9 from OpsCenter, use version OpsCenter 6.8; earlier versions are not supported. See DataStax OpsCenter compatibility with DSE.

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

    DataStax recommends the latest build of a Technology Compatibility Kit (TCK) Certified OpenJDK version 11.

    If OpenJDK, the results should look like:

    openjdk version “11.0.x” 2024-06-18
    OpenJDK Runtime Environment (build 11.0.x+xx)
    OpenJDK 64-Bit Server VM (build 11.0.x+xx, mixed mode)

    If Oracle Java, the results should look like:

    java version "11.0.x" YYYY-MM-DD LTS
    Java(TM) SE Runtime Environment 18.9 (build 11.0.x+xx-LTS)
    Java HotSpot(TM) 64-Bit Server VM (build 11.0.x+xx-LTS, mixed mode)

    If not OpenJDK 11 or Oracle Java 11, see Installing the JDK.

  2. Install the libaio package. For example:

    sudo apt-get install libaio1
  3. Add a DataStax repository file called /etc/apt/sources.list.d/datastax.sources.list:

    echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/datastax.sources.list
  4. Add the DataStax repository key:

    curl -L | sudo apt-key add -
  5. Update the packages:

    sudo apt-get update
  6. Install the DataStax Enterprise packages:

    Specify all packages; otherwise, the installation fails.

    • Install the latest version (6.9.x):

    sudo apt-get install dse-full
    • Install an earlier 6.9.x version:

    To view the available 6.9.x versions, see the Release notes. ** Install an earlier 6.9.x version:


    sudo apt-get install dse=version_number-1 \
        dse-full=version_number-1 \
        dse-libcassandra=version_number-1 \
        dse-libgraph=version_number-1 \
        dse-libhadoop2-client-native=version_number-1 \
        dse-libhadoop2-client=version_number-1 \
        dse-liblog4j=version_number-1 \
        dse-libsolr=version_number-1 \
        dse-libspark=version_number-1 \

    For example:

    Specify all packages; otherwise, the installation fails.

    sudo apt-get install dse=6.9.0-1 \
        dse-full=6.9.0-1 \
        dse-libcassandra=6.9.0-1 \
        dse-libgraph=6.9.0-1 \
        dse-libhadoop2-client-native=6.9.0-1 \
        dse-libhadoop2-client=6.9.0-1 \
        dse-liblog4j=6.9.0-1 \
        dse-libsolr=6.9.0-1 \
        dse-libspark=6.9.0-1 \
    • Optional: Install the demos:

    Installing the DSE demos is not recommended for production. Only install the demos in development environments to run tutorials.

    sudo apt-get install dse-demos=version_number-1


    DataStax Enterprise is ready for additional configuration:

    • For production, be sure to change the cassandra user. Failing to do so is a security risk. See Adding a superuser login.

    • DataStax Enterprise provides several types of workloads (default is transactional). See startup options for service or stand-alone installations.

    • Next Steps below provides links to related tasks and information.

  1. Single-node cluster installations only:

    1. Start DataStax Enterprise:

      sudo service dse start
    2. Verify that DataStax Enterprise is running by entering the nodetool status command:

      nodetool status

      Review the output to verify that DataStax Enterprise is running:

      Datacenter: Cassandra
