Django Centos 6.4 installation instructions for noobs.
So you want to build your first django centos 6.4 based web site? This is quite easy to install and configure. I’ll cover how to install Python/Django on your centos.
- CentOS 6.4 (For the matter of fact, this tutuorial is good for all the CentOS 6.x series)
- Apache (httpd)
What is Python?
“Python is a general-purpose, high-level programming language whose design philosophy emphasizes code readability. Its syntax is said to be clear and expressive.” from Wikipedia.
What is Django?
“Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design.” from https://www.djangoproject.com/
you may need the EPEL repositories for Centos.
cd /opt/ wget http://mirrors.nl.eu.kernel.org/fedora-epel/6/i386/epel-release-6-8.noarch.rpm rpm -Uvh epel-release-6-8.noarch.rpm rm epel-release-6-8.noarch.rpm -f
yum install python
test python by typing: “python” and you should see something similar to: (CTRL+D to exit)
At the time of writing (September 30 2013), the version of python@EPEL is 2.6.6
Django works with any Python version from 2.6.5 to 2.7. It also features experimental support for versions 3.2 and 3.3. All these versions of Python include a lightweight database called SQLite so you won’t need to set up a database just yet unless you need other SQL
Django works with several DB engines. for simplicity, Install SQLite:
yum install sqlite
If you need other SQL Server else then SQLite, you can follow:
MySQL/MongoDB/CouchDB on RHEL/Centos 6.3
If you don’t need SQL and you installed Python 2.5 or later, you can skip this step for now.
You can install using EPEL repositories any yum (like in the old article I wrote), but I recommend to use the easy_install method from the python-setuptools package, which I’ll show next:
yum install python-setuptools easy_install django
Test Django by typing python on your command and then:
import django print django.get_version()
As you can see, the RPM version is version 1.5.4, while the current release in the EPEL version is 1.3.1. Internationalization: in template code is not available in 1.3.1 for example but only from Django 1.4
From the command, cd into a directory where you’d like to store your app, then run the following command:
django-admin.py startproject mysite cd mysite
Note: if you are installing Django using EPEL repos, the command will be django-admin and not django-admin.py.
python manage.py runserver
You’ve started the Django development server, a lightweight Web server – easier to startwithout having to deal with configuring a production server — such as Apache — until you’re ready for production.
Browse to http://127.0.0.1:8000/ with your Web browser. You’ll see a “Welcome to Django” page. It worked!
To change port:
python manage.py runserver 8080
If you need to start the server to answer not only locally, use:
python manage.py runserver 0.0.0.0:8000
Remember: Apache loads Django environment when starting and keep running it even when source is changed! I suggest you to use Django ‘runserver’ (which automatically restarts on source code changes) in development sessions, unless you need some Apache-specific features.
Edit mysite/settings.py. It’s a normal Python module with module-level variables representing Django settings.
Django using Apache
To run your Django application inside apache – use either mod_python or mod_wsgi, Support for mod_python will be deprecated in a future release of Django. If you are configuring a new deployment, you are strongly encouraged to consider using mod_wsgi or any of the other supported backends.
OPTION A: Install mod_python (NOT recommended)
For this to work, you must have apache installed and configured.
yum install mod_python
python using mod_python
you need to configure you apache/VirtualHost to:
AddHandler mod_python .py PythonHandler mod_python.publisher | .py AddHandler mod_python .psp .psp_ PythonHandler mod_python.psp | .psp .psp_ PythonDebug On
Create a ‘test.py’ file in your apache server. put inside:
<% req.write("Hello World!") %>
and browse to www.your.server/test.py and you should see the “Hello World!” there.
Django using mod_python
Edit your httpd.conf file:
<Location "/mysite/"> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE mysite.settings PythonOption django.root /mysite PythonDebug On </Location>
Option B: Install mod_wsgi (RECOMMENDED)
Deploying Django with Apache and mod_wsgi is the recommended way to get Django into production.
yum install mod_wsgi
to use mod_wsgi, create an apache folder inside your project and create a django.wsgi file:
import os, sys sys.path.append('/var/www/django') sys.path.append('/var/www/django/mysite') os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler()
and configure your apache with:
<VirtualHost *:80> ServerName www.example.com ServerAlias www.example.com WSGIScriptAlias / /var/www/django/mysite/apache/django.wsgi # Alias /robots.txt /var/www/django/mysite/static/robots.txt # Alias /favicon.ico /var/www/django/mysite/static/favicon.ico Alias /static/admin/ /usr/lib/python2.6/site-packages/django/contrib/admin/media/ Alias /static/ /var/www/django/mysite/static/ Alias /media/ /var/www/django/mysite/media/ <Directory /var/www/django/mysite> Order allow,deny Allow from all </Directory> <Directory /var/www/django/mysite/media> Order deny,allow Allow from all </Directory> <Directory /var/www/django/mysite/static> Order deny,allow Allow from all </Directory> </VirtualHost>
