Installing DSE OpsCenter 6.5 with a tarball on any Linux distribution

Install DSE OpsCenter on any Linux Distribution or Mac OS X using the OpsCenter binary tarball.

Note: Mac OS X is supported for development and testing purposes only.

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

Prerequisites

Minimum hardware requirements for the machine on which OpsCenter runs:

2 CPU cores
2 GB of RAM available to OpsCenter

Permission and software requirements:

Latest build of a Technology Compatibility Kit (TCK) Certified OpenJDK version 8 or Oracle Java SE Runtime Environment 8 (JRE or JDK). Earlier or later versions are not supported. See installing the OpenJDK or Oracle JDK.
Attention: Although Oracle JRE/JDK 8 is supported, DataStax does more extensive testing on OpenJDK 8 starting with DSE 6.0.3. This change is due to the end of public updates for Oracle JRE/JDK 8.
Use OpsCenter Lifecycle Manager to automatically manage Java and JCE installs for DSE clusters.
DataStax recommends using a recent version of one of the major web browsers. OpsCenter does not support Internet Explorer or Microsoft Edge.
