DataStax Enterprise 4.0

Installing DataStax Enterprise on RHEL-based systems

Install DataStax Enterprise and OpsCenter using Yum repositories.

Note: To install on SUSE, use the binary tarball installation.

For a complete list of supported platforms, see DataStax Enterprise Supported Platforms.

Prerequisites

  • Yum Package Management application installed.
  • Root or sudo access to the install machine.
  • Latest version of Oracle Java SE Runtime Environment 7. See Installing the Oracle JRE.
  • Python 2.6+ (needed if installing OpsCenter).
  • Java Native Access (JNA) is required for production installations. See Installing the JNA.
  • If installing on a 64-bit Oracle Linux distribution, first install the 32-bit versions of glibc libraries.
  • If installing OpsCenter on a RHEL 5.x/CentOS 5.x machine, make sure that the EPEL (Extra Packages for Enterprise Linux) are installed. See Installing EPEL on CentOS 5.x or RHEL 5.x.
  • Some RedHat-compatible distributions do not contain the Linux Standard Base Core module (redhat-lsb-core) by default. If your distribution does not have this package, you must install it.

Also see Recommended production settings and the DataStax Enterprise Reference Architecture white paper.

The packaged releases create a cassandra user. When starting DataStax Enterprise as a service, the Cassandra and Hadoop tracker services run as this user. The service initialization script is located in /etc/init.d/dse. Run levels are not set by the package.

Procedure

These steps install DataStax Enterprise. After installing, you must configure and start DataStax Enterprise.

In a terminal window:

  1. Check which version of Java is installed:
    $ java -version
    Use the latest version of Oracle Java 7 on all nodes.
  2. Add the DataStax Yum repository to a file called /etc/yum.repos.d/datastax.repo
    [datastax] 
    name = DataStax Repo for DataStax Enterprise
    baseurl=http://username:password@rpm.datastax.com/enterprise
    enabled=1
    gpgcheck=0
    where username and password are the DataStax account credentials from your registration confirmation email.
  3. Install DataStax Enterprise:
    $ sudo yum -y install dse-full-version-1
    Note:

    dse-full installs DataStax Enterprise and the DataStax Agent.

    dse-full opscenter installs DataStax Enterprise, DataStax Agent, and OpsCenter (Optional)

    For example:

    $ sudo yum -y install dse-full-4.0.3-1 

    For production installations, DataStax recommends installing the OpsCenter separate from the cluster. See the OpsCenter documentation.

    Removing the datastax-agent package also removes the DataStax Enterprise package.

Results

DataStax Enterprise is ready for configuration.
