2、Python version:2.6.6
3、Django version:1.2.7
创建项目：
1、[root@localhost ~]#django-admin.py startproject mysite
2、[root@localhost mysite]#python manage.py startapp app01
3、[root@localhost mysite]#mkdir templates
4、[root@localhost mysite templates]#tourch login.html && tourch success.html
文件配置：
settings.py
[root@localhost mysite]# cat settings.py
# Django settings for mysite project.
DEBUG = True
TEMPLATE_DEBUG = DEBUG
ADMINS = (
# ('Your Name', 'your_email@domain.com'),
)

'default': {
'ENGINE': 'django.db.backends.', # Add 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'oracle'.

'USER': '', # Not used with sqlite3.
'PASSWORD': '', # Not used with sqlite3.
'HOST': '', # Set to empty string for localhost. Not used with sqlite3.
'PORT': '', # Set to empty string for default. Not used with sqlite3.
}
}
# Local time zone for this installation. Choices can be found here:
# http://en.wikipedia.org/wiki/List_of_tz_zones_by_name
# although not all choices may be available on all operating systems.
# On Unix systems, a value of None will cause Django to use the same
# timezone as the operating system.
# If running in a Windows environment this must be set to the same as your
# system time zone.
