WSGIScriptAlias /wsgi-scripts/ /var/www/wsgi-scripts/
<Directory /var/www/wsgi-scripts>
Order allow,deny
Allow from all
</Directory>


mkdir /var/www/wsgi-scripts/

vi /var/www/wsgi-scripts/myapp.wsgi

def application(environ, start_response):
    status = '200 OK'
    output = b'Hello World!'
    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)
    return [output]

Now chmod the file to 705

chmod 705 /var/www/wsgi-scripts/myapp.wsgi
