1. python连接mysql的connector有很多，我们选择MySQLdb
2. 让python支持MySQLdb模块
#pip2.7 install MySQL-python
3. 查看python2.7可使用的模块是否存在MySQLdb
# ipython

4. 简单封装的模块，测试没问题

self.user = user
self.passwd = passwd
#实例一开始就具备了连接和游标属性
self.conn1 = MySQLdb.connect(host=self.host,port=self.port,user=self.user,passwd=self.passwd)
self.cur1 = self.conn1.cursor()

self.cur1.execute('select ' + self.field + ' from ' + self.db + '.' + self.table)
