Mac 10.10下Python2.7+Django1.7+MySQL5.5环境搭建

1 Mac系统默认自带Python，查看版本：

命令行输入：python

Python 2.7.6 (default, Sep  9 2014, 15:04:36)

版本号为2.7.6

所以不用安装了

 

2 安装Django，最新的版本1.7

（1）首先使用easy_install安装pip（easy_install是Python的包管理工具，类似Ruby下的gem，pip是升级版的easy_install）， sudo easy_install pip

（2）安装成功后，安装Django， pip install Django==1.7

（3）查看安装路径：默认为/usr/bin，如果看到django-admin.py说明安装成功，django-admin.py是Django的管理工具，用来生成项目和应用

 

3 连接mysql

（1）安装mysql for mac，直接从官网上下载dmg文件安装即可，需要64位版本

（2）安装mysql python驱动， sudo easy_install mysql-python
如果出现

EnvironmentError: mysql_config not found

应该：

• You installed python
• You did brew install mysql
• You did export PATH=$PATH:/usr/local/mysql/bin
• And finally, you did pip install MySQL-Python

 

4 创建第一个项目

（1）创建项目：django-admin.py startproject demoproject

（2）创建应用：

cd demoproject

python manage.py startapp demoapp

创建成功

（3）修改settting.py，将demoapp加入到INSTALLED_APPS

INSTALLED_APPS = (

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'demoapp'

)

（4）修改settting.py，将默认的sqlite数据库换成mysql

DATABASES = {

    'default': {

        'ENGINE': 'django.db.backends.mysql',

        'NAME': 'djangodb',

        'USER': 'root',

        'PASSWORD': 'root',

        'HOST': '127.0.0.1',

        'PORT': '3306',                  

    }

}

（5）在demoproject下输入：python manage.py dbshell，如果能正常进入mysql命令行，则说明连接成功

5 启动应用

（1）同步数据库：执行python manage.py syncdb，第一次启动需要创建superuser，用来管理django后台

Operations to perform:

  Apply all migrations: admin, contenttypes, auth, sessions

Running migrations:

  Applying contenttypes.0001_initial... OK

  Applying auth.0001_initial... OK

  Applying admin.0001_initial... OK

  Applying sessions.0001_initial... OK

 

You have installed Django's auth system, and don't have any superusers defined.

Would you like to create one now? (yes/no): yes

Username (leave blank to use 'thierry'): thierry

Email address: [e-mail]

Password:

Password (again):

Superuser created successfully.

 

（2）启动服务：python manage.py runserver：

Performing system checks...

 

System check identified no issues (0 silenced).
