Puppet, an automated administrative engine for your Linux and Unix systems, performs administrative tasks (such as adding users, installing packages, and updating server configurations) based on a centralized specification.

Documentation (and detailed installation instructions) can be found online at the Puppet Docs site.

Generally, you need the following things installed:

• A supported Ruby version. Ruby 1.8.5, 1.8.7, and 1.9.2 are fully supported (with a handful of known issues under 1.9.2); Ruby 1.8.1 is supported on a best-effort basis for agent use only. Other versions of Ruby are used at your own risk, and Ruby 1.8.6, 1.9.0, and 1.9.1 are not recommended for compatibility reasons.

• The Ruby OpenSSL library. For some reason, this often isn't included in the main ruby distributions. You can test for it by running ruby -ropenssl -e "puts :yep". If that errors out, you're missing the library.

  If your distribution doesn't come with the necessary library (e.g., on Debian and Ubuntu you need to install libopenssl-ruby), then you'll probably have to compile Ruby yourself, since it's part of the standard library and not available separately. You could probably just compile and install that one library, though.

• Facter => 1.5.1 (available via your package manager or from the Facter site).
