python使用mysql的三个模块：mysql.connector、sqlalchemy、MySQLdb

在python中使用mysql其实很简单，只要先安装对应的模块即可，那么对应的模块都有什么？官方也没指定也没提供，pcat就推荐自己遇到的3个模块：mysql.connector、sqlalchemy、MySQLdb

------------------

1. 安装mysql.connector

MySQL Connector/Python is implementing the MySQL Client/Server protocol completely in Python. No MySQL libraries are needed, and no compilation is necessary to run this Python DB API v2.0 compliant driver.

git clone https://github.com/mysql/mysql-connector-python
cd mysql-connector-python
python setup.py install

官方文档：

http://dev.mysql.com/doc/connector-python/en/

-= 补充 =-

github上的项目总在更新，有时候需要别的依赖有时候又不需要，有的操作系统上面也默认安装了一些模块。如果安装上碰到什么问题可以留言给我。

要求：Protobuf C++ (version >= 2.6.0) and Python Protobuf (version >= 3.0.0)

2. 安装sqlalchemy

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL.

It provides a full suite of well known enterprise-level persistence patterns, designed for efficient and high-performing database access, adapted into a simple and Pythonic domain language.

git clone https://github.com/zzzeek/sqlalchemy
cd sqlalchemy
python setup.py install

官方文档：

http://www.sqlalchemy.org/docs/

3. 安装MySQLdb

MySQL python client forked from MySQLdb, but support asyncronous query

原官网github：https://github.com/dccmx/mysqldb

但推荐下面的这个改进的

This is the legacy (1.x) version of MySQLdb. While it is still being maintained, there will not be a lot of new feature development.

git clone https://github.com/farcepest/MySQLdb1
cd MySQLdb1
python setup.py install

这个MySQLdb其实不怎么推荐，另外如果要在windows里安装的话，推荐安装已经编译好的exe（不然源码安装的话各种问题）：

http://www.codegood.com/downloads

里面MySQL-python-1.2.3.win-amd64-py2.7.exe、MySQL-python-1.2.3.win32-py2.7.exe分别为64位和32位版本

（如果安装MySQLdb后提示：ImportError DLL load failed: %1 不是有效的 Win32 应用程序，那么就安装个64位版本。

如果在64位系统里不能识别到安装在其他盘上的python目录，请参考这文:http://www.cnblogs.com/pcat/p/6021497.html）

官方文档：请看github里doc文件夹里的文件
