Apache Cassandra 1.1 Documentation

Installing the DataStax Community Binaries on Windows

DataStax provides a GUI installer for installing both Cassandra and OpsCenter on Windows. Download the Windows installer for your chosen platform (32- or 64-bit Windows 7 or Windows Server 2008) from DataStax Downloads. Then follow the installation wizard to install Cassandra, the sample applications, and OpsCenter.


Before installing OpsCenter on a single node make sure you have met the following prerequisite:

Starting Services

During installation, accept the options to start the DataStax Cassandra Server and OpsCenter services automatically.

When you select to start services, the Cassandra server, the OpsCenter server, and the OpsCenter agent start automatically when the installation completes (and whenever the computer reboots).

Launching Cassandra Server and OpsCenter

To finish installing DataStax Community Edition, accept the option to launch immediately.

To launch OpsCenter at a later time, enter the following URL in a browser:


Troubleshooting OpsCenter Windows Installations

Problems starting up OpsCenter and delays in stopping the OpsCenter Agent service are easily solved.

OpsCenter does not start up:

If OpsCenter does not start up when you enter the URL to launch it, the most likely reasons are:

  • DataStax services are not running:

    Solution: Check that the Cassandra and OpsCenter services are running. If not, start them in the Control Panel.

  • Microsoft Visual C++ 2008 Redistributable Package is not installed:

    Solution: Check that this package is installed. If not, download and install the package from Microsoft for 32- and 64-bit systems.

Stopping the OpsCenter Agent service takes a long time:

Be patient. Manually stopping the OpsCenter Agent service takes time.
