Installing 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. See installing the OpenJDK or Oracle JDK.

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

End User License Agreement (EULA). By downloading this DataStax product, you agree to the terms of the EULA.

In a terminal window:

Add the DataStax Yum repository in the /etc/yum.repos.d/datastax.repo file.
```
[opscenter]
name = DataStax 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/
```
