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:

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

In a terminal window:

Add the DataStax Yum repository in the /etc/yum.repos.d/datastax.repo file.
```
[opscenter]
name = {company} Repository
baseurl = https://rpm.datastax.com/enterprise
enabled = 1
gpgcheck = 0
```
Set the gpgcheck=1 to perform a GPG signature check.
If you have enabled signature verification (gpgcheck=1), import the repository key:
```
sudo rpm --import https://rpm.datastax.com/rpm/repo_key
```
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
```
For most users, the out-of-box configuration should work just fine. If necessary, you can configure OpsCenter for your environment.
Start OpsCenter:
```
sudo service opscenterd start
```
Connect to OpsCenter in a web browser using the following URL:
```
http://opscenter-host:8888/
```
