无法使用Python的MySQLdb连接到localhost

Question

我是新手,所以可能有错误的术语,但是当我运行以下脚本时:

import MySQLdb

conn = MySQLdb.connect (host = 'localhost',
   user = 'erin',
   passwd = 'erin',
          db = 'sec')

我收到错误:

  File "/Library/Python/2.6/site-packages/MySQL_python-1.2.3-py2.6-macosx-10.6-universal.egg/MySQLdb/__init__.py", line 81, in Connect
    return Connection(*args, **kwargs)
  File "/Library/Python/2.6/site-packages/MySQL_python-1.2.3-py2.6-macosx-10.6-universal.egg/MySQLdb/connections.py", line 187, in __init__
    super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)")

该目录中没有名为mysql.sock的文件,但我不知道套接字是什么或如何使用MySQLdb模块为它指定正确的位置.

Answer 1

我设法通过将主机设置为"127.0.0.1"而不是"localhost"来解决此问题.

Answer 2

如果你的mysql套接字没有放在/tmp/mysql.sock中,你可以用它来指定它

conn = MySQLdb.connect (unix_socket = 'path_to_your_socket', host = 'localhost', user = 'erin', passwd = 'erin', db = 'sec')

编辑:对于macosx上的mamp,mysql套接字路径应该是这样的 /Applications/MAMP/tmp/mysql/mysql.sock

Answer 3

您的mysql安装可能会将套接字放在其他位置.您可以在mysql conf文件中配置它.
