Configure SSL Certificate on Apache for Django App

问题:

I've purchased a SSL certificate from namecheap.com and placed the required files on my Ubuntu server (key & crt's). I'm using mod_wsgi to serve my Django application with Apache. I'm having issues installing the SSL certificate.

Current Configuration (/etc/apache2/sites-available/000-default.conf)

<VirtualHost *:80>
        ServerAdmin [e-mail]
        #DocumentRoot /var/www/html

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        #Django Application
        Alias /static /home/Django/professor/static_root
        <Directory /home/Django/professor/static_root>
                Require all granted
        </Directory>
        <Directory /home/Django/professor/professor>
                <Files wsgi.py>
                        Require all granted
                </Files>
        </Directory>

        WSGIDaemonProcess professor python-path=/home/Django/professor:/home/Django/professor-vm/lib/python2.7/site-packages
        WSGIProcessGroup professor
        WSGIScriptAlias / /home/Django/professor/professor/wsgi.py

        #ServerName example.com
        #SSLEngine on
        #SSLCertificateFile /etc/apache2/ssl/server.crt
        #SSLCertificateKeyFile /etc/apache2/ssl/server.key
        #SSLCACertificateFile /etc/apache2/ssl/intermediate.crt

</VirtualHost>

I've commented out the lines for the SSL certificate. Currently, my application is running fine but when I uncomment the lines to enable to SSL certificate my site serves the files from /var/www and not the application. Any ideas?

Your problem is that your apache is only configured for port 80, hence it doesn't serve pages over https (port 443).

For this example I assume you want to serve your website only over https, so here is how your config should approximately look like.

Here is your: 000-default.conf

<VirtualHost *:80>
    ServerName example.com
    ServerAdmin [e-mail]

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # This is optional, in case you want to redirect people 
    # from http to https automatically.
    RewriteEngine On
    RewriteCond %{SERVER_PORT} !^443$
    RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,L]

</VirtualHost>

Now here is default-ssl.conf:

<VirtualHost *:443>
    ServerName example.com
    ServerAdmin [e-mail]

    # Django Application
    Alias /static /home/Django/professor/static_root
    <Directory /home/Django/professor/static_root>
        Require all granted
    </Directory>

    <Directory /home/Django/professor/professor>
        <Files wsgi.py>
            Require all granted
        </Files>
    </Directory>

    WSGIDaemonProcess professor python-path=/home/Django/professor:/home/Django/professor-vm/lib/python2.7/site-packages
    WSGIProcessGroup professor
    WSGIScriptAlias / /home/Django/professor/professor/wsgi.py


    SSLEngine on
    SSLCertificateFile /etc/apache2/ssl/server.crt
    SSLCertificateKeyFile /etc/apache2/ssl/server.key
    SSLCACertificateFile /etc/apache2/ssl/intermediate.crt

</VirtualHost>

After configuration is done, we need to turn on the ssl site and (optionally) rewrite mod:

> sudo a2ensite default-ssl
> sudo a2enmod rewrite
> sudo service apache2 reload

to complete Alexey's answer, when i faced the problem i had to disable the 000-default.conf site and use only ssl configuration
