为了用DB-API编写MySQL脚本，必须确保已经安装了MySQL。复制以下代码，并执行：

import MySQLdb

Traceback (most recent call last):
  File "./hello.py", line 3, in <module>
    import MySQLdb
ImportError: No module named MySQLdb

可以访问：https://pypi.python.org/pypi/MySQL-python从这里可选择适合您的平台的安装包，分为预编译的二进制文件和源代码安装包。

如果选择二进制文件发行版本的话，安装过程基本安装提示即可完成。如果从源代码进行安装的话，先下载源码然后解压缩，进入解压缩后的目录并执行：

python setup.py build

如果出现以下错误：

sh: mysql_config: command not found
Traceback (most recent call last):
  File "setup.py", line 17, in <module>
    metadata, options = get_config()
  File "/Users/macbook/Downloads/MySQL-python-1.2.5/setup_posix.py", line 43, in get_config
    libs = mysql_config("libs_r")
  File "/Users/macbook/Downloads/MySQL-python-1.2.5/setup_posix.py", line 25, in mysql_config
    raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found

则去掉mysql_config=XXX的注释，并改成mysql_config = /usr/bin/mysql_config(以mysql_config文件所在机器上的目录为准，如果不知道其目录，可以使用sudo find / -name mysql_config命令查找)

Traceback (most recent call last):
  File "./hello.py", line 3, in <module>
    import MySQLdb
  File "build/bdist.macosx-10.10-intel/egg/MySQLdb/__init__.py", line 19, in <module>
  File "build/bdist.macosx-10.10-intel/egg/_mysql.py", line 7, in <module>
  File "build/bdist.macosx-10.10-intel/egg/_mysql.py", line 6, in __bootstrap__
ImportError: dlopen(/Users/macbook/.python-eggs/MySQL_python-1.2.5-py2.7-macosx-10.10-intel.egg-tmp/_mysql.so, 2): Library not loaded: libmysqlclient.18.dylib
  Referenced from: /Users/macbook/.python-eggs/MySQL_python-1.2.5-py2.7-macosx-10.10-intel.egg-tmp/_mysql.so
  Reason: image not found

sudo ln -s /usr/local/mysql/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

注意，该软连接的实际目录部分以自己机器上的目录为准

测试代码：

import MySQLdb

# 打开数据库连接
db = MySQLdb.connect("dburl","username","password","dbname" )

# 使用cursor()方法获取操作游标 
cursor = db.cursor()

# 使用execute方法执行SQL语句
cursor.execute("SELECT VERSION()")

# 使用 fetchone() 方法获取一条数据库。
data = cursor.fetchone()

print "Database version : %s " % data

# 关闭数据库连接
db.close()

执行结果：

Database version : 5.6.16-log
