Deploy Django on Apache

Currently, Apache and mod_python are the most robust combinations for deploying Django on production servers. Mod_python is an Apache plug-in embedded with python in Apache. It loads Python code into the memory when the server starts.

Django requires support for apaceh 2.x and mod_python 3.x.

For Apache configuration, see: http://www.djangoproject.com/r/apache/docs/

 

Deploy using mod_python

1. to configure Django Based on mod_python, install Apache with the available mod_python module.

2. There should be a loadmodule command in the Apache configuration file. It looks like this:

LoadModule python_module /usr/lib/apache2/modules/mod_python.so

3. Configure Apache to locate the request URL to the Django application:

<VirtualHost *:80>
        ServerName www.example.com

        <Location "/mysite1">
            SetHandler python‐program
            PythonHandler django.core.handlers.modpython
            SetEnv DJANGO_SETTINGS_MODULE mysite1.settings
            PythonAutoReload Off
            PythonDebug Off
            PythonPath "['/var/www/html/mysite1'] + sys.path"
            PythonInterpreter mysite1
        </Location>

        <Location "/mysite2">
            SetHandler python‐program
            PythonHandler django.core.handlers.modpython
            SetEnv DJANGO_SETTINGS_MODULE mysite2.settings
            PythonAutoReload Off
            PythonDebug Off
            PythonPath "['/var/www/html/mysite2'] + sys.path"
            PythonInterpreter mysite2
        </Location>

        [......]
</VirtualHost>

It tells Apache that any URL after the path/mysite is processed using Django's mod_python. It passes the value of django_settings_module to know which configuration should be used at this time.

View the mod_python document to obtain a detailed command list.

4. Restart Apache and check http: // www.example.com/mysite:

/etc/init.d/apache2 restart

Deploy with mod_wsgi

1. download and install the mod_wsgi module and generate mod_wsgi.so and wsgi. conf.

2. Load the module in Configuration:

LoadModule python_module /usr/lib/apache2/modules/mod_wsgi.so

3. Modify the Apache configuration file httpd. conf.

<VirtualHost *:80>
        ServerName www.example
        DocumentRoot /var/www/html/mysite
        WSGIScriptAlias / /var/www/html/mysite/apache/django.wsgi
        <Directory />
                Order deny,allow
                Allow from all
        </Directory>
        <Directory /apache>
                Allow from all
        </Directory>
</VirtualHost>

4. Create and configure the wsgi configuration file:

# filename:mysite.apache.django.wsgi

import os, sys

#Calculate the path based on the location of the WSGI script.
apache_configuration= os.path.dirname(__file__)
project = os.path.dirname(apache_configuration)
workspace = os.path.dirname(project)
sys.path.append(workspace)
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
os.environ['PYTHON_EGG_CACHE'] = '/tmp'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
print >> sys.stderr, sys.path    
shell>chmod a+x django.wsgi

5. modify the configuration file settings. py of the Django project:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mysite',                     
        'USER': 'admin',                      
        'PASSWORD': 'admin123',                  
        'HOST': '127.0.0.1',                     
        'PORT': '3306', }
}

TEMPLATE_DIRS = (
    '/var/www/html/mysite/templates',
)

6. Restart Apache to access http://www.example.com/mysite

/etc/init.d/apache2 restart
