Zenoss, Inc., makes several installation packages of Zenoss Core available to meet the needs of its community. For a list of current installation packages, visit www.zenoss.com/download. You'll find native packages, stack installers, and source files for several operating systems: Red Hat Enterprise Linux, Centos, Ubuntu, Fedora Core, OS X, OpenSuse, and Debian. The stack installers and native packages include all Zenoss Core dependencies.
If you need a no fuss installation to use as a sandbox or to follow along with the book, then I recommend loading one of the Zenoss Core VMware appliances for Windows, Linux, or OS X. To run the appliance, download the VMware Player or VMware Server for free from www.vmware.com.
