本文实例讲述了django框架创建应用操作。分享给大家供大家参考，具体如下：

18.1.5 安装Django

安装Django

node2:/root#pip install Django
/usr/local/python27/lib/python2.7/site-packages/cryptography/hazmat/primitives/constant_time.py:26: CryptographyDeprecationWarning: Support for your Python version is deprecated. The next version of cryptography will remove support. Please upgrade to a 2.7.x release that supports hmac.compare_digest as soon as possible.
utils.DeprecatedIn23,
Looking in indexes: http://mirrors.aliyun.com/pypi/simple/
Requirement already satisfied: Django in /usr/local/python27/lib/python2.7/site-packages (1.11.9)
Requirement already satisfied: pytz in /usr/local/python27/lib/python2.7/site-packages (from Django) (2017.2)
You are using pip version 18.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

18.1.6 在Django 中创建项目:

node2:/django/mysite#django-admin.py startproject learning_log
node2:/django/mysite#ls -ltr

-rwxrwxrwx 1 root root 804 Oct 25 2017 manage.py
-rwxrwxrwx 1 root root 608 Nov 25 2017 query_mysql.py
drwxrwxrwx 3 root root 4096 Nov 27 2017 form
drwxrwxrwx 2 root root 4096 Nov 27 2017 online
-rwxrwxrwx 1 root root 262 Dec 5 2017 test.py
-rwxrwxrwx 1 root root 646 Dec 5 2017 test.pyc
-rwxrwxrwx 1 root root 113 Dec 5 2017 __init__.pyc
drwxrwxrwx 2 root root 4096 Dec 5 2017 home
-rwxrwxrwx 1 root root  0 Dec 5 2017 __init__.py
-rwxrwxrwx 1 root root  27 Dec 5 2017 a1.py
-rwxrwxrwx 1 root root  5 Dec 5 2017 celerybeat.pid
drwxrwxrwx 7 root root 4096 Dec 12 2017 static
drwxrwxrwx 4 root root 4096 Jan 28 2018 blog
drwxrwxrwx 2 root root 4096 Sep 16 2018 portal
drwxrwxrwx 2 root root 4096 Apr 24 10:15 mysite
drwxrwxrwx 4 root root 4096 Apr 25 02:17 news
drwxr-xr-x 3 root root 4096 Apr 25 09:25 learning_log

/django/mysite/learning_log/learning_log

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'learning_log',

18.1.7 创建数据库

Django 将大部分与项目相关的信息都存储在数据库中,因此我们需要创建一个供Django使用的数据库

配置mysql数据库

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'tlcb',
'USER': 'root',
'PASSWORD': '1234567',
'HOST': '192.168.137.3',
'PORT': '3306',
}
}

node2:/django/mysite/learning_log#python manage.py migrate
Operations to perform:
Apply all migrations: admin, auth, contenttypes, sessions
Running migrations:
Applying contenttypes.0001_initial... OK
Applying auth.0001_initial... OK
Applying admin.0001_initial... OK
Applying admin.0002_logentry_remove_auto_add... OK
Applying contenttypes.0002_remove_content_type_name... OK
Applying auth.0002_alter_permission_name_max_length... OK
Applying auth.0003_alter_user_email_max_length... OK
Applying auth.0004_alter_user_username_opts... OK
Applying auth.0005_alter_user_last_login_null... OK
Applying auth.0006_require_contenttypes_0002... OK
Applying auth.0007_alter_validators_add_error_messages... OK
Applying auth.0008_alter_user_username_max_length... OK
Applying sessions.0001_initial... OK
node2:/django/mysite/learning_log#

18.1.8 创建应用:

django-admin.py startproject learning_log

希望本文所述对大家基于Django框架的Python程序设计有所帮助。
