Now to deploy in a first step an application on the fix IP with our a domain name

Hey! There are a lot of ways to deploy a Django project. Are you running into a specific issue?

To deploy a Python app in a virtualenv using Mod_wsgi and Apache, first install the dependencies:

sudo apt-get install python-pip python-virtualenv libapache2-mod-wsgi apache2

Now put your Django project files onto the server and create your virtualenv. Generally a directory in /var/www/ will do. They key is to make sure to use the correct path is in your Apache configuration. If your virtualenv is located in /var/www/myapp/ then your Apache config (/etc/apache2/sites-enabled/000-default.conf ) would be:

<VirtualHost *:80>
    ServerName www.example.com
    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/myapp

    WSGIDaemonProcess myapp python-path=/var/www/myapp:/var/www/myapp/env/lib/python2.7/site-packages
    WSGIProcessGroup myapp
    WSGIScriptAlias / /var/www/myapp/myapp/wsgi.py

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