我在mysql中有一个数据库，我想连接到它 . 我试图从Python中使用这个名为MySQLdb的模块 . 我为这个数据库（abc）创建了一个用户（称为abc）和密码（abc），它有一个表并且连接正常（当我通过mysql命令行连接时） .
但是当我运行我的python脚本时，连接中出现错误 . 我的脚本是：
#!/usr/bin/python
import MySQLdb
# Open database connection
db = MySQLdb.connect("localhost","abc","abc","abc")
# prepare a cursor object using cursor() method
cursor = db.cursor()
# execute SQL query using execute() method.
cursor.execute("SELECT VERSION()")
# Fetch a single row using fetchone() method.
data = cursor.fetchone()
print "Database version : %s " % data
# disconnect from server
db.close()
我的错误是：
Traceback (most recent call last):
File "./test.py", line 8, in <module>
db = MySQLdb.connect("localhost","abc","abc","abc")
File "/usr/local/lib/python2.7/dist-packages/MySQLdb/__init__.py", line 81, in Connect
return Connection(*args, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/MySQLdb/connections.py", line 193, in __init__
super(Connection, self).__init__(*args, **kwargs2)
_mysql_exceptions.OperationalError: (1044, "Access denied for user 'abc'@'localhost' to database 'abc'")
怎么了？我的脚本或我的mysql中的东西？我将我的localhost更改为127.0.0.1（正如另一篇文章所述，但没有解决我的问题 .
我还检查了我对这个mysql用户的权限：
SHOW GRANTS;
+------------------------------------------------------------------------------+
| Grants for abc@localhost |
+------------------------------------------------------------------------------+
| GRANT USAGE ON *.* TO 'abc'@'localhost' |
| GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, CREATE VIEW ON `abc`.* TO 'abc'@'localhost' |
+------------------------------------------------------------------------------+

您可能需要重新启动mysql守护程序才能使权限生效 . 或者使用
flush privileges命令 . https://dev.mysql.com/doc/refman/5.7/en/privilege-changes.html
