Install DSE OpsCenter 6.8 from the Debian package

Install DSE OpsCenter 6.8 using APT repositories on Debian or Ubuntu distributions.

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

The OpsCenter Debian and Ubuntu packaged releases runs as a service from root. 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:

Permission and software requirements:

APT Package Manager is installed.
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 Install the Java Virtual Machine.

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
DataStax recommends using a recent version of one of the major web browsers. OpsCenter does not support Internet Explorer or Microsoft Edge.

In a terminal window:

Modify the aptitude repository source list file (/etc/apt/sources.list.d/datastax.sources.list).

echo "deb https://debian.datastax.com/enterprise \
stable main" | sudo tee -a /etc/apt/sources.list.d/datastax.sources.list

Add the DataStax repository key to your aptitude trusted keys:

curl -L https://debian.datastax.com/debian/repo_key | sudo apt-key add -

Install the OpsCenter package using the APT Package Manager:
```
sudo apt-get update
```
```
sudo apt-get install opscenter
```
If you are installing an earlier version of OpsCenter, add the supported version to the command:
```
sudo apt-get 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/
