Deploying Django on Apache2 with mod_wsgi - Correct location for Django project?

问题

I am trying to deploy my first Django project on my webserver. I am both new to server configuration and Django so I have a hard time finding my errors.

In most tutorials I have seen online, the Django project on the production server is created in /var/www/myproject - however, the Django documentation recommends putting the code outside of /var/www/ for security reasons (see: https://docs.djangoproject.com/en/1.9/intro/tutorial01/).

So, I put my Django project in a subdirectory of my home folder, which is not accessible to Apache. I added no file to /var/www as no tutorial mentions that this would be necessary.

After setting up Django with mod_wsgi according to these tutorials:
(https://docs.djangoproject.com/en/1.9/howto/deployment/wsgi/modwsgi/ ,
https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-apache-and-mod_wsgi-on-ubuntu-14-04 ,
http://tutorial.djangogirls.org/en/deploy/)
when I access my webserver via browser all I see is the default index.html site. Running and accessing the development server of Django from my webserver does not work either. In both cases, when I try to access the admin page I get a standard 404 Error.

Am I supposed to put some files into /var/www/ after all?

Could it be an issue that I use a Let'sEncrypt certificate and during the setup with auto-certbot chose to automatically redirect http to https?

Some of my configured files (I left out parts that I didn't change/have nothing to do with Django):

/etc/apache2/apache2.conf

LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so

/etc/apache2/sites-available/000-default.conf

    DocumentRoot /var/www/html

    Alias /static /home/me/django/mysite/app/static
    <Directory /home/me/django/mysite/app/static>
            Require all granted
    </Directory>

    <Directory /home/me/django/mysite/mysite>
            <Files wsgi.py>
                    Require all granted
            </Files>
    </Directory>

    WSGIDaemonProcess mysite python-path=/home/me/django/mysite:/home/me/django/djangoenv/lib/python2.7/site-packages
    WSGIProcessGroup mysite
    WSGIScriptAlias / /home/me/django/mysite/mysite/wsgi.py

/home/me/django/mysite/mysite/wsgi.py

import os
import sys

path = '/home/sirhys/django/mysite'  
if path not in sys.path:
    sys.path.append(path)

os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

from django.core.wsgi import get_wsgi_application
from django.contrib.staticfiles.handlers import StaticFilesHandler
application = StaticFilesHandler(get_wsgi_application())

/home/me/django/mysite/mysite/settings.py

DEBUG = False

ALLOWED_HOSTS = [
        'www.mysite.com',
        'mysite.com'
]

SITE_ROOT = os.path.dirname(os.path.realpath(__file__))
STATIC_ROOT = os.path.join(SITE_ROOT, '..', 'app/static')
STATIC_URL = '/static/'

Thank you!

Edit:
In the end, I found the issue to be a conflict between the different out-of-the-box config files I have on my server. Apparently, the Let's Encrypt SSL config file was overriding all other files in /etc/apache2/sites-available. When I put the WSGI-config lines there, it worked like a charm.
I have my code in my home directory now, and it is working. I decided to put my static files into /var/www/static via collectstatic. This is working for me but it seems the exact location of code and static files is really irrelevant.

Your config only for one website, need use virtual host

Example deploy:

For python3 install mod_wsgi (debian based system)

apt-get install libapache2-mod-wsgi-py3

Put your project in standard apache location

/var/www/myproj

where myproj = name you django project

Check project

python3 manage.py check

or/and run it

python3 manage.py runserver 0.0.0.0:8000

if your domain example.com, then http://example.com:8000/ or use server IP.

Allow apache2 read and write content

chown www-data:www-data /var/www/myproj -R

Config apache 2.4

cd /etc/apache2/sites-available
editor myproj.conf

and Apache2.4 minimal config (many sites)

<VirtualHost *:80>
ServerName example.com
ServerAlias www.example.com

DocumentRoot /var/www/myproj

WSGIDaemonProcess example.com python-path=/var/www/myproj

WSGIScriptAlias / /var/www/myproj/myproj/wsgi.py \
    process-group=example.com application-group=%{GLOBAL}

<Directory /var/www/myproj/myproj>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>

# static
Alias /media/ /var/www/myproj/media/
Alias /static/ /var/www/myproj/static/
Alias /robots.txt /var/www/myproj/robots.txt
# logs
ErrorLog /var/log/apache2/myproj-error.log
LogLevel warn
CustomLog /var/log/apache2/myproj-access.log combined

</VirtualHost>

Virtualenv: python path + virtual, example

python-path=/path/www/myproj python-home=/path/to/venv

Using daemon mode exclusively, add to /etc/apache2/mods-available/wsgi.load

WSGIRestrictEmbedded On

Enable config

a2ensite myproj.conf

Check syntax

apachectl -t

Restart apache or reload

service apache2 restart

Example config apache2.4 with define variable. Django > 1.6. Set only domain, path, name project. In example path to dir /var/www/example.com/myproject/myproect/wsgi.py, static url /media/ and /static/

Define:

domain - your domain name (example.com)
path - full path to project, folder where manage.py (/var/www/example.com/myproj)
project - name project, folder name where wsgi.py (myproj)

https://gist.github.com/leotop/9a78c10c0961cdd2bbe9633d6ebf8a5b

<VirtualHost *:80>
Define domain example.com
Define path /var/www/${domain}/myproj
Define project myproj


ServerName ${domain}
ServerAlias www.${domain}

DocumentRoot ${path}

WSGIDaemonProcess ${domain} python-path=${path}

WSGIScriptAlias / ${path}/${project}/wsgi.py \
    process-group=${domain} application-group=%{GLOBAL}

<Directory ${path}/${project}>
    <Files wsgi.py>
        Require all granted
    </Files>
</Directory>


Alias /media/ ${path}/media/
Alias /static/ ${path}/static/
Alias /robots.txt ${path}/static/robots.txt
Alias /favicon.ico ${path}/static/favicon.ico

<Location "/media/">
    Options -Indexes

<Location "/static/">
