Installing DataStax Enterprise 5.1 on Debian-based systems using APT

Instructions for installing DataStax Enterprise (DSE) 5.1 on Debian-based systems using APT.

Some things to know about installing DSE

  • When installed with 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 DataStax Enterprise 5.1 and the DataStax Agent. It does not install OpsCenter, Studio, or Graph Loader.

    The DataStax Installer has options to install developer related tools: Javadoc, DataStax Enterprise demos, DataStax Studio, and the DSE Graph Loader.

  • If using OpCenter 6.0, override the default DataStax Agent. See compatibility of OpsCenter with DSE. After installation:

    $ sudo apt-get install datastax-agent-6.0.supported_version-1

    You can also install the agent during installation by adding datastax-agent-6.0.supported_version-1 to the installation command in 5.


When DSE is installed, it creates a superuser called cassandra in the database and runs as this user. It also creates this same superuser in the operating system. Do not use the cassandra superuser in production. Using the cassandra superuser 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 8.

    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 the JDK.

  2. 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
  3. Add the DataStax repository key:

    $ curl -L | sudo apt-key add -
  4. Update apt-get:

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

    Specify all packages; otherwise, the installation fails.

    • Install any 5.1.x version:

    To view the available versions, see the Release notes.

    $ 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 \
    sudo apt-get install dse=5.1-1 \
        dse-full=5.1-1 \
        dse-libcassandra=5.1-1 \
        dse-libgraph=5.1-1 \
        dse-libhadoop2-client-native=5.1-1 \
        dse-libhadoop2-client=5.1-1 \
        dse-liblog4j=5.1-1 \
        dse-libsolr=5.1-1 \
        dse-libspark=5.1-1 \
    • 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 Creating superuser accounts.

  • 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. 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

      Results using vnodes:

      Datacenter: Cassandra
      |/ State=Normal/Leaving/Joining/Moving
