[cs615asa] Some questions about env setup and X.509 certificate

[zding4]

Hi everyone and professor,

I follow the documentation of AWS 
CLI(http://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-set-up.html), and I already launch my OmniOS instance.
But I found I didn't do anything like changing to your shell's startup 
files, environment variables and X.509 certificate.
Do I miss something or it's automatically done when I run $ aws 
configure?

Sincerely,
Zhizhuo
