mysql的接口错误

Question

我安装了 mysql connector/python 并且正在使用 MAMP。当我尝试连接到数据库时，这是终端中出现的内容：

Traceback (most recent call last):
File "database.py", line 7, in <module>
    raise_on_warnings= True)
File "/Library/Python/2.7/site-packages/mysql/connector/__init__.py", line 179, in connect
        return MySQLConnection(*args, **kwargs)
  File "/Library/Python/2.7/site-packages/mysql/connector/connection.py", line 95, in __init__
    self.connect(**kwargs)
  File "/Library/Python/2.7/site-packages/mysql/connector/abstracts.py", line 719, in connect
    self._open_connection()
  File "/Library/Python/2.7/site-packages/mysql/connector/connection.py", line 206, in _open_connection
    self._socket.open_connection()
  File "/Library/Python/2.7/site-packages/mysql/connector/network.py", line 475, in open_connection
    errno=2003, values=(self.get_address(), _strioerror(err)))
mysql.connector.errors.InterfaceError: 2003: Can't connect to MySQL server on 'localhost:8889:3306' (60 Operation timed out)

我尝试进入 connector 文件夹 并检查了 network.py 脚本，似乎错误是由于接口错误引起的。文档说：

此异常是针对源自连接器/Python 本身的错误引发的，与 MySQL 服务器无关。

errors.InterfaceError 是 errors.Error 的子类

如果需要，这是我的 Python 脚本：

import mysql.connector

con = mysql.connector.connect(user='root',
                              password ='root',
                              host='localhost',
                              database='testdb',
                              raise_on_warnings= True)

cur = con.cursor()

cur.close()
con.close()

如何摆脱界面错误？

Answer 1

从您的主机中删除端口和冒号：

 con = mysql.connector.connect(user='root',
                               password ='root',
                               host='localhost',
                               database='testdb',
                               raise_on_warnings= True)

您的端口已设置为 3306
