Install Apache Python mod_wsgi

When you install LAMP, php is installed with apache and mysql but in for django you have to install them individually.

First you need to install Python Apache Mod_wsgi. The mod_wsgi is an Apache module used to serve Python scripts over HTTP.

For python 3 you need to install for py3.

$ sudo apt install libapache2-mod-wsgi-py3

Restart Apache. Now create a file on webfolder 'test_wsgi_script.py'.

def application(environ,start_response):
    status = '200 OK'
    html = '\n' \
           '\n' \
           'Alhamdulillah, mod_wsgi is working\n' \
           '\n' \
           '\n'
    response_header = [('Content-type','text/html')]
    start_response(status,response_header)
    return [html]

Now create a configuration file eg. /etc/apache2/conf-available/mod-wsgi.conf with the following contents.

WSGIScriptAlias /test_wsgi /var/www/scripts/test_wsgi_script.py

Enable it.

$ sudo a2enconf mod-wsgi
$ sudo systemctl restart apache2

The Python script is ready to serve over Apache. You can test the script by accessing the URL http://fi3fi.com/test_wsgi in a web browser.

You will notice that this applies system wide and may not be ideal if you have several virtual sites or environment. So lets do for a specific vhost.

<VirtualHost *:80>
ServerName fi3fi.com
 ServerAdmin webmaster@localhost
   WSGIScriptAlias /test_wsgi /var/www/scripts/test_wsgi_script.py
        DocumentRoot /var/www/scripts/

        Options Indexes FollowSymLinks MultiViews

        ErrorLog ${APACHE_LOG_DIR}/error-fi3fi.log
        CustomLog ${APACHE_LOG_DIR}/access-fi3fi.log combined
</VirtualHost>
