这个问题在这里已经有答案了：

mysql:如何允许远程连接mysql（16个答案）
两年前关门了。
我正在尝试将数据从另一个连接到localhost的系统发送到xampp的mysql数据库。
我已经批准了 xampp.conf 但我仍然面临同样的问题。
下面是我面临的两个错误。

Traceback (most recent call last):
  File "test.py", line 7, in <module>
    db = MySQLdb.connect(host="192.168.0.142", user="safepro", passwd="Safepro@123", db="ers")
  File "/usr/lib/python3/dist-packages/MySQLdb/__init__.py", line 81, in Connect
    return Connection(*args,**kwargs)
  File "/usr/lib/python3/dist-packages/MySQLdb/connections.py", line 204, in __init__
    super(Connection, self).__init__(*args,**kwargs2)
_mysql_exceptions.OperationalError: (1130, "Host 'SP004-PRECISION' is not allowed to connect to this MariaDB server")

Traceback (most recent call last):
  File "test.py", line 7, in <module>
    db = MySQLdb.connect(host="127.0.0.1", user="safepro", passwd="Safepro@123", db="ers")

    super(Connection, self).__init__(*args,**kwargs2)
_mysql_exceptions.OperationalError: (1045, "Access denied for user 'safepro'@'localhost' (using password: YES)")

 Help me with the solution, where should I change the setting.

谢谢。
