Re: Deploying SSL for my Django 2.0.1 server with Apache on Ubuntu 16.04 (droplet)

The username on my droplet is 'tranq' but there is a line in both my vhost config files which reads:

<Directory /home/user/cel2fah/cel2fah/>

So I swapped out 'user' for 'tranq'. That line now reads:

<Directory /home/tranq/cel2fah/cel2fah/>

Now some of my static files are accessible.  For example you can see here:

https://www.angeles4four.info/static/admin/css/responsive.css

https://www.angeles4four.info/static/admin/css/login.css

But the following is still saying, "Forbidden":

https://www.angeles4four.info/static/admin/

This may be pointing to an issue I noticed with how my user and group permissions are set up for Django.  The sqlite.db file was grouped in with 'tranq'. According to the guide I've been using, it should be: 'www-data'.  I'm not sure how I overlooked this mistake because I very clearly remember doing it properly.  I think I'm conflating this with one of my multiple recent previous attempts following this guide. Anyways, here is what my group permissions look like now from within my project directory:

$ ls -la

total 68

drwxrwxr-x  5 tranq www-data  4096 Jan 25 23:12 .

drwxr-xr-x 18 tranq tranq     4096 Jan 26 21:57 ..

drwxrwxr-x  3 tranq tranq     4096 Jan 25 23:13 cel2fah

-rw-rw-r--  1 tranq www-data 38912 Jan 25 23:11 db.sqlite3

-rwxrwxr-x  1 tranq tranq      539 Jan 25 23:05 manage.py

drwxrwxr-x  3 tranq tranq     4096 Jan 25 23:12 static

drwxrwxr-x  5 tranq tranq     4096 Jan 25 23:04 venv

Notice sqlite.db above? It now says 'www-data'.  This is how it should be, right?

The parent directory (home user folder) shows these permissions for my project:

...

drwxrwxr-x  5 tranq www-data  4096 Jan 25 23:12 cel2fah

Does this look right to all of you?

The steps I took to arrange the permissions as such were from the bottom of the mod_wsgi guide on DigitalOcean which I referred to initially.

Thanks for your attention.

You're right, @Antonis, that I don't want my Django source code exposed. No sysadmin would.  I have since moved my Django project folder to my home user's directory. However (out of curiosity), if I continued to house Django in my public_html folder (which I am not any more, but say if i did) I would think that my .htaccess config file would prevent unauthorized access to my Django source.  Am I right?

I didn't realize that Django was suppose to be run using wsgi.  I was just foolishly running the server with ``$ python manage.py runserver 0.0.0.0:8000`` like when I was testing locally when I was coding my app. The keyword here is mod_wsgi.  So I found this guide. I followed along but the issue I now have is that Apache serves my public_html folder (just some light  HTML, CSS and Js).  Serving these contents take priority over Django.  I'm OK with this. I would prefer to keep my public_html folder accessible as it is, but how do I arrange for wsgi to serve Django from a subdirectory, say: www.angeles4four.info/cel2fah or something like that?

@Mulianto:

An example of a static file would be a style sheet, like: ~/cel2fah/static/admin/css/responsive.css

How would trying to access this CSS file help?

I tried:

http://www.angeles4four.info:8000/cel2fah/static/admin/css/responsive.css

https://www.angeles4four.info:8000/cel2fah/static/admin/css/responsive.css

I've played with a little Django (v2.0.1) locally. Now I am trying to implement a test case on my production Apache web server. I'm running an Ubuntu 14.04 DigitalOcean droplet (will upgrade to 18.04 later this year).

I got Django running.

Here it is: http://www.angeles4four.info:8000/

Before I log into my admin panel, I figure it's best practices to set up HTTPS first. But when I visit that URL, Chrome throws this message:

This site can't provide a secure connection http://www.angeles4four.info sent an invalid response. ERR_SSL_PROTOCOL_ERROR

And my shell on my server shows this message:

[20/Jan/2018 23:54:39] "GET / HTTP/1.1" 200 16559 [21/Jan/2018 00:01:23] code 400, message Bad request syntax ('\x16\x03\x01\x00Ì\x01\x00\x00È\x03\x03&6U\x10µ\x82\x97\x7f´8\x1e«\x0e¿ÿ§\x89æ\x82\r¢G§\x01ç°P%\x80)ÕÃ\x00\x00\x1c * À+À/À,À0̨̩À\x13À\x14\x00\x9c\x00\x9d\x00/\x005\x00') [21/Jan/2018 00:01:23] You're accessing the development server over HTTPS, but it only supports HTTP.

That's because SSL isn't set up. My current SSL Certificate Authority is Let's Encrypt. SSL is running properly for my public_html content but not for my recent deployment of Django.

I found some resources elsewhere on SO for setting up SSL with Django.

In an SO post titled, "Configure SSL Certificate on Apache for Django Application (mod_wsgi)", a highly upvoted answer by Alexey Kuleshevich suggests a template for 000-default.conf and default-ssl.conf for Apache vhosts. See here: Configure SSL Certificate on Apache for Django Application (mod_wsgi)

I did my best to change up the suggested values and entries so that they refer to my specific configuration. Here are what these two vhost configuration files of mine look like now.

No dice. I still get the same traceback as I initially shared.

The next SO post I came across suggests modifying settings.py. Here it is: Error "You're accessing the development server over HTTPS, but it only supports HTTP"

The upvoted suggestion here by YoYo is to modify session cookies and secure SSL redirect. YoYo also recommends managing base, local, production settings which doesn't really apply to me. So I tried adding these three lines to my settings.py:

SESSION_COOKIE_SECURE = True
CSRF_COOKIE_SECURE = True
SECURE_SSL_REDIRECT = True

My python3 manage.py runserver shell traceback still says: "You're accessing the development server over HTTPS, but it only supports HTTP."

Any ideas? What else could I try?

Thanks for your attention.
