Python MySQLdb连接

Question

我想将我的数据从json传输到mysql，为此我安装了python库MySQLdb。它成功导入，但在连接时出错

>>> import MySQLdb
>>> db=MySQLdb.connect(passwd="king123",db="thangs")

Traceback (most recent call last):
  File "<pyshell#1>", line 1, in <module>
    db=MySQLdb.connect(passwd="king123",db="thangs")
  File "C:\Python27\lib\site-packages\MySQLdb\__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "C:\Python27\lib\site-packages\MySQLdb\connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

>>> import _mysql
>>> db=_mysql.connect()

Traceback (most recent call last):
  File "<pyshell#3>", line 1, in <module>
    db=_mysql.connect()
OperationalError: (2003, "Can't connect to MySQL server on 'localhost' (10061)")

db=MySQLdb.connect(passwd="rat123",db="thangs",host="localhost",port=1028,user="mroot")

Traceback (most recent call last):
  File "<pyshell#41>", line 1, in <module>
db=MySQLdb.connect(passwd="king123",db="thangs",host="localhost",port=1028,user="munieb")

Answer 1

您需要指定server and point。

db=MySQLdb.connect(passwd="king123",db="thangs",host="hostname",port=3251,user="user")

Answer 2

我也有同样的问题，对我来说，问题是mysql监听端口3305的ip地址。通过netstat -aon我看到：

Proto  Local Address          Foreign Address        State           PID
...
TCP    0.0.0.0:3306            0.0.0.0:0              LISTENING       884
...

所以我取消了my.ini配置文件下面的注释行：

#bind-address="127.0.0.1" 

然后重新启动mysql，问题就解决了！
