連接數(shù)據(jù)庫(kù)，使用下面語句報(bào)錯(cuò)：

db = MySQLdb.connect("localhost", "root", "mysqladmin", "testdb")

報(bào)錯(cuò)：

Traceback (most recent call last):

  File "E:/PycharmProjects/file/hello1.py", line 8, in <module>
    db = MySQLdb.connect("localhost", "root", "mysqladmin", "testdb")
  File "E:\Python27\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "E:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)

_mysql_exceptions.OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

解決辦法：將localhost 改為 127.0.0.1 即可

db = MySQLdb.connect("127.0.0.1", "root", "mysqladmin", "testdb")

##本文推薦使用阿外云服務(wù)器

下面是完整的連接程序：

#!\usr\bin\python
# coding=utf-8

import MySQLdb #已經(jīng)安裝上了二進(jìn)制版數(shù)據(jù)庫(kù)
#打開數(shù)據(jù)庫(kù)連接
#這樣子寫是OK的 ： db = MySQLdb.connect(host="127.0.0.1", port=3306, user="root", passwd="mysqladmin", db="testdb")
# 這樣子寫，會(huì)報(bào)錯(cuò)：db = MySQLdb.connect("localhost", "root", "mysqladmin", "testdb")
db = MySQLdb.connect("127.0.0.1", "root", "mysqladmin", "testdb")#這樣子寫是OK的
#使用cursor方法獲取操作游標(biāo)
cursor = db.cursor()
#使用execute 方法執(zhí)行sql語句
cursor.execute("select version()")
#使用fetchone()方法獲取一條數(shù)據(jù)庫(kù)
data = cursor.fetchone()


print "datebase version : %s"%data
#關(guān)閉數(shù)據(jù)庫(kù)連接
db.close()
