Installing DataStax Enterprise 6.8 on a single node

Use these instructions to install a single instance of DataStax Enterprise (DSE) on Linux-based platforms using a binary tarball. This single node can introduce you to DSE, which includes DSE Security, DataStax Graph, DSE Analytics, and DSE Search.

This installation is intended only for demonstration purposes. For other installations, see Which install method should I use?

Some things to know about installing DataStax Enterprise:

  • These instructions apply to all versions of DataStax Enterprise 6.8. For specific changes please see the DSE 6.8 release notes.

  • When installed from the binary tarball, DataStax Enterprise runs as a stand-alone process.

  • When DSE is installed, it creates a cassandra user in the database and runs as this user. Do not use the cassandra user in production. Using the cassandra user is a security risk. See Adding a superuser login.

Prerequisites

Java 8. If you don’t have a recent version of Java 8, download and install OpenJDK 8.

Procedure

End User License Agreement (EULA). By downloading this DataStax product, you agree to the terms of the EULA.

In a terminal window:

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

    java -version

    If OpenJDK, the results should look like:

    openjdk version "1.8.0_242"
    OpenJDK Runtime Environment (build 1.8.0_242-b09)
    OpenJDK 64-Bit Server VM (build 25.242-b09, mixed mode)

    If Oracle Java, the results should look like:

    java version "1.8.0_241"
    Java(TM) SE Runtime Environment (build 1.8.0_241-b11)
    Java HotSpot(TM) 64-Bit Server VM (build 25.241-b11, mixed mode)

    If not Oracle Java 8 or OpenJDK 8, see Installing supporting software on DataStax Enterprise 6.8.

    Package management tools do not install Oracle Java.

  2. Install the libaio package. For example:

    • RHEL platforms:

      sudo yum install libaio
    • Debian platforms:

      sudo apt-get install libaio1
  3. Use curl to download and install DSE:

    Your password is retained in the shell history. To avoid this security issue, DataStax recommends using curl with the --netrc or --netrc-file option.

    curl -L https://downloads.datastax.com/enterprise/dse.tar.gz | tar xz

    The files are downloaded and extracted into the 6.8 directory.

  4. Create the default data and logging directories:

    • /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
  5. Start DataStax Enterprise from the installation directory:

    bin/dse cassandra
  6. Verify that DataStax Enterprise is running from the installation directory:

    bin/nodetool status

    Results:

    Datacenter: Cassandra
