Installing OpsCenter with the standalone installer

Installs the DataStax OpsCenter web application with a standalone GUI installer on Mac OS X, or on any Linux distribution with a standalone command line installer.

The standalone installer installs OpsCenter using either a GUI installer on Mac OS X, or a command line installer on any Linux distribution. The DataStax agent is not installed with the standalone installer. The agent is installed when DSE or Cassandra is installed, or you can manually install the agents. For more information, see Installing DataStax agents.

Prerequisites

Root or sudo access when installing as a system service, and if installing missing system dependencies.
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.

Procedure

Download the installer for your operating system from the DataStax OpsCenter download page:
- Mac OS X
- Linux
Launch the installer:
- (Mac OSX) Double-click the downloaded .dmg file.
- (Linux) Follow these steps:
  1. From the directory where you downloaded the install file, change the permission to executable:
```
$ chmod +x DataStaxOpsCenter-5.1.0.version number-linux-64-installer.run
```
  2. Start the installation:
```
$ ./DataStaxOpsCenter-5.1.0.version number-64-linux-installer.run
```
Follow the instructions in the install wizard.
The installation completes. If you installed as a service and selected Launch OpsCenter Web Interface in the wizard, OpsCenter opens in your default browser. Otherwise, continue with the next step.
