在連接mysql數(shù)據(jù)庫函數(shù)中指定socket文件，如下： 

#!/usr/bin/python
from MySQLdb import connect
conn = connect(db="pzy", user="root", host="localhost", unix_socket="/storage/db/mysql/mysql.sock")
cur = conn.cursor()
count=cur.execute("show databases")
print 'there has %s dbs' % count
conn.commit()
conn.close()
