Second, version 12 defaults to using authentication keys to communicate between a Chef Workstation and a Chef Server. There are also a number of other changes, such as the new Chef Development Kit. Note that this guide uses Enterprise Linux 6.5 instead of Ubuntu 12.04. This guide will also provide instructions on how to setup Chef when the environment is behind a http proxy. (more…)

Note, this guide is for Chef version 11. See the post “Install a (Version 12) Chef Server, Workstation and Client” for a guide on installing Chef version 12.
