I can answer the question one by one:
Is if fine that Apache, PostgreSQL, and Python are installed all over the place in the Django environment?
All over the place sounds weird but yes it is totally fine.
Did I miss a core Django component and/or directory?
No you don't miss anything, Django core is in
site-packages
folder already and your site code ismysite
, which can be located anywhere you want.Will deploying and scaling be a problem?
No it won't be a problem with current structure. You will deploy your
mysite
only, the other will be installed separately.
Something you should get familiar with when starting with Django development:
Most likely when you deploy your project, it will be on a Linux server, so install and learn Linux maybe?
virtualenv: Soon you will have to install Django, then a bunch of external packages to support your project.
virtualenv
helps you isolate your working environment. Well it's "unofficial" a must when you start with python development.virtualenvwrapper to make your life easier when working with
virtualenv
git and github or bitbucket: if you don't know
git
yet, you should now.
