Installing DataStax Enterprise 4.7 using the binary tarball

Install DataStax Enterprise on any Linux-based platform.

These steps install DataStax Enterprise, the DataStax Agent, and OpsCenter (optional). After installing, you must configure and start DataStax Enterprise.

In a terminal window:

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. Download the tarball from the download-previous-versions page using the DataStax Academy account credentials you created on the registration page. Be sure to use your registration email address, not your username.

   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 \|.
3. Unpack the distribution:

   $ tar -xzvf dse-4.7.X.tar.gz

   The files are extracted into the dse-4.7.X directory.

4. If you do not have root access to the default directories locations, you can define your own directory locations as described in the following steps or change the ownership of the directories:
   • /var/lib/cassandra
   • /var/log/cassandra
   • /var/lib/spark
   • /var/log/spark

   $ 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/spark; sudo chown -R  $USER:$GROUP /var/lib/spark
   $ sudo mkdir -p /var/log/spark; sudo chown -R  $USER:$GROUP /var/log/spark

5. Optional: If you do not want to use the default data and logging directories, you can define your own directory locations:
   1. Make the directories for data and logging directories:

      $ mkdir install_location/dse-data
      $ cd dse-data
      $ mkdir commitlog
      $ mkdir saved_caches

   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:

      Package installations	/etc/dse/cassandra/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

6. Optional: If you do not want to use the default Spark directories, you can define your own 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

7. Optional: Review the installation logs to verify the installation.
