  • Root or sudo access to the install machine.

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.

Procedure

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. Add a DataStax repository file called /etc/apt/sources.list.d/datastax.sources.list:
    $ echo "deb https://dsa_email_address:password@debian.datastax.com/enterprise stable main" | sudo tee -a /etc/apt/sources.list.d/datastax.sources.list
    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.
  3. Add the DataStax repository key:
    $ curl -L https://debian.datastax.com/debian/repo_key | sudo apt-key add -
    Note: If you have trouble adding the key, use http instead of https.
  4. Install the packages:
    1. $ sudo apt-get update
    2. Install the package: (Use for all product levels.)
      $ sudo apt-get install dse-full=4.7.X-1 dse=4.7.X-1 dse-hive=4.7.X-1 dse-pig=4.7.X-1 dse-demos=4.7.X-1 dse-libsolr=4.7.X-1 dse-libtomcat=4.7.X-1 dse-libsqoop=4.7.X-1 dse-liblog4j=4.7.X-1 dse-libmahout=4.7.X-1 dse-libhadoop-native=4.7.X-1 dse-libcassandra=4.7.X-1 dse-libhive=4.7.X-1 dse-libpig=4.7.X-1 dse-libhadoop=4.7.X-1 dse-libspark=4.7.X-1

      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 \|.
