Installing OpsCenter from the Debian package

Install DataStax OpsCenter using APT repositories on Debian or Ubuntu distributions.

For a complete list of supported platforms, see DataStax 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.
JRE or JDK (recommended) is only required if HTTPS or opscenterd/agent SSL is enabled (off by default). See installing the Oracle JDK or OpenJDK.
DataStax recommends using a recent version of one of the major web browsers. OpsCenter does not support Internet Explorer or Microsoft Edge.
Python 2.6+.

In a terminal window:

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

$ echo "deb http://debian.datastax.com/community stable main" | sudo tee -a /etc/apt/sources.list.d/datastax.community.list

Add the DataStax repository key to your aptitude trusted keys:
```
$ curl -L https://debian.datastax.com/debian/repo_key | sudo apt-key add -
```
Note: If you have trouble adding the key, use http instead of https.
Install the OpsCenter package using the APT Package Manager:
```
$ sudo apt-get update
$ sudo apt-get install opscenter
```

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/
```

Add an existing cluster or provision a new cluster.
