Procedure

These steps install DataStax Enterprise. They do not install OpsCenter, DataStax Studio, DataStax Agent, or DevCenter. After installing, you must configure and start DataStax Enterprise.

Important: End User License Agreement (EULA). By downloading DataStax products, you confirm that you agree to the processing of information as described in the DataStax website privacy policy and agree to the website terms of use.

In a terminal window:

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

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

    Important: Package management tools do not install Oracle Java.
  2. Download and extract the DataStax Enterprise tarball using your

    To install the latest version (5.0.15):

    curl -L https://downloads.datastax.com/enterprise/dse-5.0.15-bin.tar.gz | tar xz

    To install earlier versions, use the version number in the above command. For example:

    curl -L https://downloads.datastax.com/enterprise/dse-5.0.3-bin.tar.gz | tar xz
    The latest version of DataStax Enterprise 5.0.x is 5.0.15.

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

    The files are downloaded and extracted into the dse-5.0.15 directory.

  3. To use the default data and logging directory locations, create the directories and change ownership:
    • /var/lib/cassandra
    • /var/log/cassandra (includes audit directory, debug.log, gremlin.log, solrvalidation.log, system.log)
    • /var/lib/dsefs
    • /var/lib/spark
    • /var/log/spark
    • /var/lib/spark/rdd
    • /var/lib/spark/worker
    sudo mkdir -p /var/lib/cassandra; sudo chown -R  $USER:$GROUP /var/lib/cassandra
    $ sudo mkdir -p /var/log/cassandra; sudo chown -R  $USER:$GROUP /var/log/cassandra
    $ sudo mkdir -p /var/lib/dsefs; sudo chown -R  $USER:$GROUP /var/lib/dsefs
  4. Make the directories for data and logging directories:
    1. For example:
      mkdir installation_location/dse-data
      $ cd dse-data
      $ mkdir commitlog
      $ mkdir saved_caches
      $ mkdir hints
    2. Go the directory containing the cassandra.yaml file:
      cd install_location/resources/cassandra/conf
    3. Edit the following lines in the cassandra.yaml file:
      The location of the cassandra.yaml file depends on the type of installation:
      Installer-Services /etc/dse/cassandra/cassandra.yaml
      Package installations /etc/dse/cassandra/cassandra.yaml
      Installer-No Services install_location/resources/cassandra/conf/cassandra.yaml
      Tarball installations install_location/resources/cassandra/conf/cassandra.yaml
      data_file_directories: install_location/dse-data
      commitlog_directory: install_location/dse-data/commitlog
      saved_caches_directory: install_location/dse-data/saved_caches
      hints_directory: install_location/dse-data/hints
  5. Optional: If using DataStax analytics, to define your own Spark directory locations:
    1. Make the directories for the Spark lib and log directories.
    2. Edit the spark-env.sh file to match the locations of your Spark lib and log directories, as described in Configuring Spark nodes.
      The default location of the spark-env.sh file depends on the type of installation:
      Installer-Services and Package installations /etc/dse/spark/spark-env.sh
      Installer-No Services and Tarball installations install_location/resources/spark/conf/spark-env.sh
    3. Make a directory for the DSEFS data directory and set its location in dsefs_options.

    DataStax Enterprise is ready for additional configuration.

  6. Optional: Single-node cluster installations only:
    1. Start DataStax Enterprise from the installation directory:
      bin/dse cassandra
      Note: For other start options, see Starting DataStax Enterprise as a stand-alone process.
    2. Verify that DataStax Enterprise is running:
      If using vnodes:
      nodetool status
      Datacenter: Cassandra
      =====================
      Status=Up/Down
      |/ State=Normal/Leaving/Joining/Moving

      If using not using vnodes:
