Install DSE OpsCenter as an RPM package
You can install DSE OpsCenter 6.8 from an RPM package on CentOS, RHEL, and Oracle Linux (OL) machines.
For all supported platforms, see Supported platforms for DSE.
Prepare the infrastructure
Install OpsCenter on a separate machine from your intended DataStax Enterprise (DSE) nodes.
The OpsCenter machine must meet the following requirements:
-
At least 2 CPU cores
-
At least 2 GB of RAM available to OpsCenter
-
The latest build of Technology Compatibility Kit (TCK) Certified OpenJDK version 8 or Oracle Java SE Runtime Environment 8 (JRE or JDK). Other versions aren’t supported.
Although Oracle JRE/JDK 8 is supported, DataStax does more extensive testing on OpenJDK 8. This change is due to the end of public updates for Oracle JRE/JDK 8.
After installing OpsCenter, you can use Lifecycle Manager (LCM) to automatically manage Java and JCE installs for DSE clusters.
