Installing DataStax Enterprise 5.1 using the binary tarball

Instructions for installing DataStax Enterprise 5.1 on any supported Linux-based platform.

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

   java -version

   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.
   • Package management tools do not install OpenJDK 8 or Oracle Java.
2. When installing from the binary tarball, you can either download the tarball and then extract the files, or use curl.
   • Download and extract the tarball specifying the version:
     Note: The latest version is 5.1.12. To view the available versions, see the Release notes.
     1. Using your Your DataStax Academy registration Profile Name and Downloads Key or email address and password, download the tarball from Download DataStax Enterprise.
     2. Extract the files:

        tar -xzvf dse-5.1.12-bin.tar.gz

   • Using curl to download and extract the tarball:
     CAUTION: If you choose to run the curl command, your password is retained in the shell history. To avoid this DataStax recommends using curl with the --netrc or --netrc-file option. Alternately, download the tarball from DataStax downloads.

     curl --user DSA_profile_name:downloads_key -L \
     https://downloads.datastax.com/enterprise/dse-5.1.12-bin.tar.gz | tar xz

     where DSA_profile_name and downloads_key are your DataStax Academy Profile Name and My Downloads Key. 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 \|.

     For backward compatibility, you can use your DataStax Academy email address and password instead of your Profile Name and Downloads Key.

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

3. You can use either the default data and logging directory locations or define your locations:
   • To use the default data and logging directory locations, create and change ownership for the following:

     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 &&
     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 &&
     sudo mkdir -p /var/lib/spark/rdd; sudo chown -R  $USER:$GROUP /var/lib/spark/rdd &&
     sudo mkdir -p /var/lib/spark/worker; sudo chown -R  $USER:$GROUP /var/lib/spark/worker

   • To define your own data and logging directory locations:
     1. In the installation_location, make the directories for data and logging directories. For example:

        mkdir installation_location/dse-data &&
          cd dse-data &&
          mkdir commitlog &&
          mkdir saved_caches &&
          mkdir hints &&
          mkdir cdc_raw

     2. Go the directory containing the cassandra.yaml file:

        cd installation_location/resources/cassandra/conf 

     3. Edit the following lines in the cassandra.yaml file:

        data_file_directories: full_path_to_installation_location/dse-data
        commitlog_directory: full_path_to_installation_location/dse-data/commitlog
        saved_caches_directory: full_path_to_installation_location/dse-data/saved_caches
        hints_directory: full_path_to_installation_location/dse-data/hints
        cdc_raw_directory: full_path_to_installation_location/cdc/raw

   • Optional: Define your own Spark directories:
     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.
     3. Make a directory for the DSEFS data directory and set its location in dsefs_options.

     spark-env.sh

     The default location of the spark-env.sh file depends on the type of installation:

     Package installations Installer-Services installations	/etc/dse/spark/spark-env.sh
     Tarball installations Installer-No Services installations	installation_location/resources/spark/conf/spark-env.sh

   DataStax Enterprise is ready for additional configuration.

4. You can use either the default data and logging directory locations or define your locations:
   • Default directory locations: If you want to use the default data and logging directory locations, create and change ownership for the following:
     • /var/lib/cassandra
     • /var/log/cassandra

     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

   • Define your own directory locations: If you want to define your own data and logging directory locations:
     1. In the installation_location, make the directories for data and logging directories. For example:

        mkdir dse-data; chown -R $USER:$GROUP dse-data &&
          cd dse-data && 
          mkdir commitlog; chown -R $USER:$GROUP commitlog && 
          mkdir saved_caches; chown -R $USER:$GROUP saved_caches &&
          mkdir hints; chown -R $USER:$GROUP hints && 
          mkdir cdc_raw; chown -R $USER:$GROUP cdc_raw

     2. Go the directory containing the cassandra.yaml file:

        cd installation_location/resources/cassandra/conf

     3. Update the following lines in the cassandra.yaml file to match the custom locations:

        data_file_directories: 
                - full_path_to_installation_location/dse-data
        commitlog_directory: full_path_to_installation_location/dse-data/commitlog
        saved_caches_directory: full_path_to_installation_location/dse-data/saved_caches
        hints_directory: full_path_to_installation_location/dse-data/hints
        cdc_raw_directory: full_path_to_installation_location/cdc_raw

5. Optional: You can use either the default Spark data and logging directory locations or define your locations:
   • Default directory locations: If you want to use the default Spark directory locations, create and change ownership for the following:
     • /var/lib/dsefs
     • /var/lib/spark
     • /var/log/spark

     sudo mkdir -p /var/lib/dsefs; sudo chown -R $USER:$GROUP /var/lib/dsefs && 
       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 &&
       sudo mkdir -p /var/lib/spark/rdd; sudo chown -R $USER:$GROUP /var/lib/spark/rdd  &&
       sudo mkdir -p /var/log/spark/master; sudo chown -R $USER:$GROUP /var/log/spark/master  &&
       sudo mkdir -p /var/log/spark/alwayson_sql; sudo chown -R $USER:$GROUP /var/log/spark/alwayson_sql  &&
       sudo mkdir -p /var/lib/spark/worker; sudo chown -R $USER:$GROUP /var/lib/spark/worker

   • Define your own directory locations: If you want to define your own Spark directory locations:
     1. In the installation_location, make the directories for data and logging directories. For example:

        mkdir dsefs; chown -R $USER:$GROUP dsefs &&
          mkdir spark; chown -R $USER:$GROUP spark &&  
          cd spark && 
          mkdir log; chown -R $USER:$GROUP log &&
          mkdir rdd; chown -R $USER:$GROUP rdd && 
          mkdir worker; chown -R $USER:$GROUP worker &&
          cd log &&
          mkdir worker; chown -R $USER:$GROUP worker &&
          mkdir master; chown -R $USER:$GROUP master &&
          mkdir alwayson_sql; chown -R $USER:$GROUP alwayson_sql

     2. Go the directory containing the spark-env.sh file:

        cd installation_location/resources/spark/conf

     3. Uncomment and update the following lines in the spark-env.sh file:

        export SPARK_WORKER_DIR="full_path_to_installation_location/spark/worker"
        export SPARK_EXECUTOR_DIRS="full_path_to_installation_location/spark/rdd"
        export SPARK_WORKER_LOG_DIR="full_path_to_installation_location/spark/log/worker"
        export SPARK_MASTER_LOG_DIR="full_path_to_installation_location/spark/log/master"
        export ALWAYSON_SQL_LOG_DIR="full_path_to_installation_location/spark/log/alwayson_sql"

     4. Go to the directory containing the dsefs_options file:

        cd installation_location/resources/dse/conf

     5. Uncomment and update the DSEFS directory in dse.yaml:

        work_dir: full_path_to_installation_location/dsefs

   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. From the installation directory, verify that DataStax Enterprise is running:

      bin/nodetool status
