Have you looked at README.md at
<URL:
https://github.com/web2py/py4web> ?
This should make a small stand-alone server and one or more sample applications.
If you have looked at that introduction, what questions do you still have?
Also, look at the py4web documentation at
<URL:
py4web.com/_documentation/static/index.html#chapter-01>
I haven't heard of any training videos yet (the older framework, web2py, has several, but those wouldn't be useful for py4web).
If you need to learn more about setting up a front-end server, such as NginX, you should consult the NginX website.
(the web2py position on Apache is that if you don't have it already, you should consider NginX or other easier-to-use front ends.)
Good luck!
