Installing DataStax Enterprise 5.1 on Debian-based systems using APT

Instructions for installing DataStax Enterprise 5.1 using APT repositories on Debian-based systems. Root permissions are required.

In a terminal window:

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 not OpenJDK 8 or Oracle Java 8, see Installing supporting software.

   Important:

   • Although Oracle JRE/JDK 8 is supported, DataStax does more extensive testing on OpenJDK 8 starting with DSE 5.1.11. This change is due to the end of public updates for Oracle JRE/JDK 8. Java 9 is not supported.
   • Package management tools do not install OpenJDK 8 or Oracle Java.
2. 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

3. Add the DataStax repository key:

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

4. Update apt-get:

   sudo apt-get update

5. Install the DataStax Enterprise package:
   Attention: Specify all packages; otherwise, the installation fails.
   • Install the latest 5.1.x version:

     sudo apt-get install dse=5.1.15-1 \
       dse-full=5.1.15-1 \
       dse-libcassandra=5.1.15-1 \
       dse-libgraph=5.1.15-1 \
       dse-libhadoop2-client-native=5.1.15-1 \
       dse-libhadoop2-client=5.1.15-1 \
       dse-liblog4j=5.1.15-1 \
       dse-libsolr=5.1.15-1 \
       dse-libspark=5.1.15-1 \
       dse-libtomcat=5.1.15-1

   • Install an earlier 5.1.x version:
     Note: 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 \
       dse-libtomcat=version_number-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

   DataStax Enterprise is ready for additional configuration.

6. 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
