The RDO (http://openstack.redhat.com) repositories contain both the binary and source RPM files. The EL-6 versions are available here:

• http://repos.fedorapeople.org/repos/openstack/openstack-grizzly/epel-6/

To install just the compute service run these commands while logged as the root user:

# yum install http://repos.fedorapeople.org/repos/openstack/openstack-grizzly/rdo-release-grizzly-3.noarch.rpm
# yum install openstack-nova-compute python-cinderclient

The first enables the RDO repository, the second installs just the compute service and the block storage client (required for nova to access cinder volumes). The source RPM for compute is here:

http://repos.fedorapeople.org/repos/openstack/openstack-grizzly/epel-6/openstack-nova-2013.1.2-1.el6.src.rpm

Rebuilding it generates all of the openstack-compute-* sub-packages including those which package the Python scripts which deploy to the bin directory.
