Installing DataStax Enterprise 6.0 on Debian-based systems using APT

Instructions for installing DataStax Enterprise 6.0 using APT repositories on Debian-based systems. Root permissions are required.

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

   java -version

   Note: 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. 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 https://debian.datastax.com/enterprise/ stable main" | sudo tee -a /etc/apt/sources.list.d/datastax.sources.list

4. Add the DataStax repository key:

   curl -L https://debian.datastax.com/debian/repo_key | sudo apt-key add -

5. Update the packages:

   sudo apt-get update

6. Install the DataStax Enterprise packages:
   Attention: Specify all packages; otherwise, the installation fails.
   • Install any 6.0.x version:
     Note: To view the available 6.0.x 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 \
         dse-libtomcat=version_number-1

     For example:

     sudo apt-get install dse=6.0.x-1 \
         dse-full=6.0.x-1 \
         dse-libcassandra=6.0.x-1 \
         dse-libgraph=6.0.x-1 \
         dse-libhadoop2-client-native=6.0.x-1 \
         dse-libhadoop2-client=6.0.x-1 \
         dse-liblog4j=6.0.x-1 \
         dse-libsolr=6.0.x-1 \
         dse-libspark=6.0.x-1 \
         dse-libtomcat=6.0.x-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 apt-get install dse-demos=version_number-1

   Result

   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 .
   • DataStax Enterprise provides several types of workloads (default is transactional). See startup options for service or stand-alone installations.
   • What's next below provides links to related tasks and information.
7. Optional: Single-node cluster installations only:
   1. Start DataStax Enterprise:

      sudo service dse start

   2. Verify that DataStax Enterprise is running:

      nodetool status

      Results using vnodes:
