About the installer 

The DataStax installer installs DataStax Enterprise and DataStax Studio if developer_install is specified. It does not install OpsCenter or DevCenter. See Installing OpsCenter or Installing DevCenter.

You can use this installer to set cassandra.yaml and dse.yaml properties with the following template files:
  • cassandra_yaml_template
  • dse_yaml_template

The DataStax Enterprise download page provides a sample_install_5.0.prop file.

Procedure

Note: The latest version of DataStax Enterprise is 5.0.9.
In a terminal window:

  1. Download the installer for your computer from the DataStax download page or use the following command:
    $ curl --user dsa_email_address:password -O https://downloads.datastax.com/enterprise/DataStaxEnterprise-5.0.9-linux-x64-installer.run
    Note: To install earlier versions, replace the version number in the above command. To view the available versions, see the Release Notes.
  2. From the directory where you downloaded the install file, change the permission to executable:
    $ chmod +x DataStaxEnterprise-5.0.9-linux-x64-installer.run
  3. You can either use the command line or a properties file:
    • Command line:
      $ sudo ./DataStaxEnterprise-5.0.9-linux-x64-installer.run --option argument --option argument ... --option argument --mode unattended
      For available options, see the table below. Be sure to add "--" to the option. For example:
      $ sudo ./DataStaxEnterprise-5.0.9-linux-x64-installer.run --enable_vnodes 0 --mode unattended

      The installer uses the default value for any unspecified option.

    • Properties file:
      $ sudo ./DataStaxEnterprise-5.0.9-linux-x64-installer.run --optionfile option_file_name --mode unattended
      where option_file_name is the name of the file containing the installation options. For example:
      $ sudo ./DataStaxEnterprise-5.0.9-linux-x64-installer.run --optionfile ../datastax/DC4-analytics.prop --mode unattended
      Properties file format: option=argument. For example:
      install_type=simple
      update_system=1

      The properties file options are the same as the command line options without the --.

      Custom installation location example:
      $ sudo ./DataStaxEnterprise-5.0.9-linux-x64-installer.run --optionfile ../datastax/custom_location.prop --mode unattended
      system_install=no_services
      prefix=/home/dse
