pymysql連接mysql數據庫時出現的問題

1. 出現的問題

   Traceback (most recent call last):
   File “”, line 1, in
   File “D:\Python27\lib\site-packages\pymysql_init_.py”, line 94, in Connect
   return Connection(*args, **kwargs)
   File “D:\Python27\lib\site-packages\pymysql\connections.py”, line 325, in init
   self.connect()
   File “D:\Python27\lib\site-packages\pymysql\connections.py”, line 599, in connect
   self._request_authentication()
   File “D:\Python27\lib\site-packages\pymysql\connections.py”, line 861, in _request_authentication
   auth_packet = self._read_packet()
   File “D:\Python27\lib\site-packages\pymysql\connections.py”, line 684, in _read_packet
   packet.check_error()
   File “D:\Python27\lib\site-packages\pymysql\protocol.py”, line 220, in check_error
   err.raise_mysql_exception(self._data)
   File “D:\Python27\lib\site-packages\pymysql\err.py”, line 109, in raise_mysql_exception
   raise errorclass(errno, errval)
   pymysql.err.OperationalError: (1045, u"Access denied for user ‘root’@‘PC-111362’ (using password: YES)")

2. 原因
   mysql數據庫的授權設置存在問題

3. 解決辦法

use mysql;
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY '123456'; 
flush privileges;
