How to get OpenStack
OpenStack is a large and fast moving project. We are also an upstream project, with a large community of packagers and distributions who redistribute our work.
The best way to install OpenStack is to rely on one of the downstream distributions, which will take care of many of the details for you. There are also source code installers oriented towards developers.
Also, you don't have to install OpenStack - there are Cloud services that can provide OpenStack, without ever installing the software.

Linux Distributions Including OpenStack
OpenStack is available for all major Linux Distributions. Refer to the install documentation for more:
For those that deploy rather than install, there are several DevOps options for automating your installation of OpenStack.
There are multiple Chef cookbooks, but there is a dedicated community of developers from AT&T, IBM, Rackspace and other companies working on the set on StackForge:
- StackForge Chef repository for deployment
- StackForge Chef cookbook repositories for each OpenStack service
There are alternative repositories available:
- Rackspace Cloud Builders maintain a set of repositories with openstack-related chef cookbooks on github at 
- Dell Crowbar is an OpenStack deployment solution built on top of Chef. They maintain their Chef recipes on github at crowbar/crowbar
- SUSE Cloud Admin Appliance is powered by OpenStack and allows you to deploy OpenStack quickly and easily using Crowbar on Chef
- Puppet Labs maintains a set of puppet modules for OpenStack at puppetlabs/puppetlabs-openstack.
- NII developed a Puppet-based tool called dodai-deploy. It is available for download on github at nii-cloud/dodai-deploy. Documentation for dodai-deploy can be found on the wiki at its github site.
- RDO, at openstack.redhat.com, is a packaging of OpenStack for Red Hat distributions (Fedora, RHEL, CentOS, SL) using Packstack, which uses Puppet.
For developers, there are installers that create a core development environment.
