Webfaction + Pyenv = Django.md

For some reason it's always a struggle to get a flexible Django install running on Webfaction. This ended up working.

Create a mod_wsgi application - latest version of mod_wsgi and Python probably.

Go into the application and clone this repo:

git clone [email protected]:<gh_username>/<gh_project_name>.git <app_name>

Create a pyenv:

$ mkdir -p ~/.virtualenvs

In your .bash_profile, append this:

# Default Python
# http://docs.webfaction.com/software/python.html#creating-a-python-alias
alias python=python3.4

# Default pyvenv
alias pyvenv=pyvenv-3.4

# Default pip
alias pip=pip3.4

… and then reload your profile:

$ source ~/.bash_profile

create the pyenv:

$ pyvenv ~/.virtualenvs/<app_name>

in apache2/conf/http.conf:

ServerRoot "/home/<username>/webapps/<app_name>/apache2"

from django.core.wsgi import get_wsgi_application

Use logging.basicConfig(filename='log_file_name.log', level=logging.DEBUG) for debugging the wsgi.py file.

Then, copy over your local settings:

cp <app_name>/settings_local_sample.py <app_name>/settings_local.py

And edit them as necessary
