django新建项目，连接mysql数据库

安装django，进入Django目录，运行 python setup.py install

在workplace目录下新建一个名为site01的项目：

cd workplace
django-admin.py startproject site01 ，在workplace目录下自动生成site01目录及其里面的内容

在site01下新建一个名为app01的app：

python manage.py startapp app01

启动项目site01下的WEB服务：
cd site01
python manage.py runserver 0.0.0.0:80

django配置连接mysql数据库

1.python需要先安装mysql模块，否则在django的settings.py中配置mysql连接后，在python manage.py runserver的时候会报错“django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module: No module named MySQLdb”

2.配置相应project下的settings.py，默认使用mysql，修改如下：

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'testly',  #db name
'USER': 'root', #db user
'PASSWORD': '123456789',
'HOST':'192.168.1.1', #db server
'PORT':'3306', #留空表示默认端口
}
}

在运行python manage.py migrate同步数据库时，如果出现如下报错则说明连接mysql的用户没有足够的权限，dba添加相应权限即可

注：root'@'192.168.50.74 全部是用户名



安装MySQL-python步骤如下（Windows10）：

1.运行python mysqlregistry.py，否则在安装MySQL-python时候会提示找不到python2.7
2.http://www.dlldll.com/ 下载libguide40.dll和 libmmd.dll这两个文件，然后拷贝到C:\WINDOWS/system32/ 目录下
3.http://www.codegood.com/downloads 下载MySQL-python-1.2.3.win-amd64-py2.7.exe

安装完成后在python下可以导入import MySQLdb
