My replies are getting pretty long winded, so I'll turn this into a dedicated answer.

You said you already have a configuration set up with a master and two agents. That's a great start.

https://puppetlabs.com/blog/quest-lea... and http://learn.puppetlabs.com/ are great places to start.

For your next step, I would suggest some of the following options.

1) Learn about module design. The puppetlabs docs are really great on this topic. One gotcha is containment and anchoring, That bit me a few times until I really started to understand how it worked.

2) Get involved with a module that you use/plan on using from the puppetforge. Read the codebase. Read the tests. Read the issues/pull requests.

3) Start learning about mcollective. mcollective seems to be the industry standard for cluster orchestration and management for systems using puppet. I would look at the mcollective-vagrant project. Be sure to look though the puppet modules used to craft the Virtualbox VM. They are a great example of a common pattern for module layout and design. This same style recommendation is reflected in the official puppet docs linked above.

4) Lots of great examples on rnelson0's blog. I would recommend learning about the r10k based workflow, integrating rspec-puppet tests into your modules, and integrating hiera for seperating your data from your code, as well as the roles and profiles pattern.

5) For more of the same from #3 but with a fun perspective to read, check out Shit Gary Says The talks on the workflow, and using hiera contain lots of great information.

When I import the ova file into Vm workstation. I power up the virtual machine and it says: "CentOS linux 7 core" I need ubuntu... and "this kernel requires an x86-64 CPU, but only detects an i686 CPU, This processor is unsupported in CentOS 7" I don't see in the site, how can I download ubuntu vm .

If the exercises use CentOS 7 why can't you just use CentOS 7?

There are no differences between using Puppet on CentOS and Ubuntu. Don't worry about that.
