Python 学习入门（4）—— 连接 MySQL

下载 MySQL for Python，最新版 MySQL-python-1.2.4b4.tar.gz

1）提前安装：mysql_config 环境

否则后面 python setup.py build 会提示找不到 “EnvironmentError: mysql_config not found”，安装命令如下：

sudo apt-get install libmysqlclient-dev

2）然后，再安装MySQLdb

$ tar zxvf MySQL-python-1.2.2.tar.gz
$ cd MySQL-python-1.2.2
$ sudo python setup.py build
$ sudo python setup.py install

3）验证成功安装
