Install DSE OpsCenter 6.8 from the RPM package

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

The CentOS, RHEL, and OL OpsCenter packaged releases create an opscenter user. OpsCenter runs as a service and runs as the opscenter user. The service initialization script is located in /etc/init.d.

If the OpsCenter machine reboots, OpsCenter restarts automatically. To disable, restart upon reboot:

sudo update-rc.d opscenterd disable

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:

An IBMid.
- If you are an existing IBM customer with an IBMid, you can continue to use your established account.
- If you don’t have an IBMid, you can create one.

Yum package management utility.
Latest build of a TCK (Technology Compatibility Kit) Certified OpenJDK version 8 or Oracle Java SE Runtime Environment 8 (JRE or JDK). Earlier or later versions are not 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.
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.

Procedure

Download the OpsCenter RPM packages from Fix Central:
1. Sign in to Fix Central.
2. In the Product selector field, enter IBM DataStax OpsCenter.
3. Select the version you want to install from the Release list, and then click Continue.

6. Review the terms and conditions, and then click I agree.
Click the DSE RPM package link to download the file, for example, opscenter-6.8.47-rpm.zip.
Extract the RPM files from the .zip file:
```
unzip opscenter-6.8.47-rpm.zip
```
You can use the package signing public key (rpm-signing.pub.key) in the file to set up and verify the RPM packages.
Import the package signing public key:
```
sudo rpm --import rpm-signing.pub.key
```
Set up a local Yum repository to host the downloaded RPM files.
- Apache
- nginx
- Red Hat Satellite
See Apache in the Red Hat documentation for more information.

See nginx in the Red Hat documentation for more information.

See Uploading content to custom RPM repositories in the Red Hat Satellite documentation for more information.
Add the local DataStax Yum repository to a file called /etc/yum.repos.d/datastax.repo:
```
[datastax]
name={company} Repo for DSE
baseurl=file://**REPOSITORY_DIRECTORY_PATH**
enabled=1
```
Specify all packages; otherwise, the installation fails.
Install the OpsCenter package:
```
sudo yum install opscenter
```
If you are installing an earlier version of OpsCenter, add the supported version to the command:
```
sudo yum install -y opscenter-6.8.VERSION_NUMBER
```
The default configuration is suitable for most deployments. If necessary, you can configure OpsCenter for your environment.
Start OpsCenter:
```
sudo service opscenterd start
```
Connect to OpsCenter in a web browser at http://opscenter-host:8888/.
