Installing DataStax Enterprise 6.0 on RHEL-based systems using Yum

Instructions for installing DataStax Enterprise 6.0 using Yum repositories on RHEL-based systems.

Instructions for installing DataStax Enterprise (DSE) 6.0 on RHEL-based systems using Yum.

To install on SUSE, use the binary tarball installation.

Some things to know about installing DataStax Enterprise:

  • The latest version of DataStax Enterprise 6.0 is 6.0.x.
  • When installed from a package (Yum or APT), DataStax Enterprise runs as a service. The service initialization script is located in /etc/init.d/dse. Run levels are not set by the package.
  • This procedure installs DSE 6.0 and the DataStax Agent. It does not install OpsCenter, DataStax Studio, Graph Loader, or DataStax Bulk Loader.
  • When connecting to DSE 6.0 from OpsCenter, use version OpsCenter 6.5; earlier versions are not supported. See DataStax OpsCenter compatibility with DSE.
Warning: When DSE is installed, it creates a cassandra user in the database. Do not use the cassandra user in production. Failing to do so is a security risk. See .

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 OpenJDK, the results should look like:
    openjdk version "1.8.0_171"
    OpenJDK Runtime Environment (build 1.8.0_171-8u171-b11-0ubuntu0.16.04.1-b11)
    OpenJDK 64-Bit Server VM (build 25.171-b11, mixed mode)
    If Oracle Java, the results should look like:
    java version "1.8.0_181"
    Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
    Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)

    If not OpenJDK 8 or Oracle Java 8, see Installing the JDK..

  2. Install the libaio package. For example:
    sudo yum install libaio
  3. Add the DataStax Yum repository to a file called /etc/yum.repos.d/datastax.repo:
    Note: Set the gpgcheck=1 to perform a GPG signature check.
    [datastax] 
    name=DataStax Repo for DataStax Enterprise
    baseurl=https://rpm.datastax.com/enterprise/
    enabled=1
    gpgcheck=0
  4. If you have enabled signature verification (gpgcheck=1), import the DataStax Enterprise repository key:
    sudo rpm --import https://rpm.datastax.com/rpm/repo_key 
  5. Install the DataStax Enterprise packages:
    Attention: Specify all packages; otherwise, the installation fails.
    • Install any 6.0.x version:

          dse-liblog4j-6.0.version_number-1 \
          dse-libspark-6.0.version_number-1
      For example:
      sudo yum install dse-6.0.x-1 \
          dse-full-6.0.x-1 \
          dse-libgraph-6.0.x-1 \
          dse-libcassandra-6.0.x-1 \
          dse-libhadoop2-client-6.0.x-1 \
          dse-libsolr-6.0.x-1 \
