PyCharm - 数据库连接。用户'root'@'localhost'拒绝访问（使用密码：YES）

Question

我正在尝试通过PyCharm为我的本地db（mysql）设置连接。我正在开发macbook pro。

我正在使用此video。

但是，当我尝试测试连接时，我收到了这个错误：

    Connection to Data Source failed
java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

    in LocalDataSource.getConnection(LocalDataSource.java:158)

但我没有问题通过终端连接到mysql

mysql -u root --password=123

UPD

mysql -u root -p -h 127.0.0.1 -D lp
Access denied for user 'root'@'localhost' (using password: YES)

mysql -u root -p -h 127.0.0.1 lp
Access denied for user 'root'@'localhost' (using password: YES)

mysql -u root -p -h localhost lp
connected

UPD

mysql> select host, user, password != '' from mysql.user;
+-----------+------+----------------+
| host      | user | password != '' |
+-----------+------+----------------+
| localhost | root |              1 |
| 127.0.0.1 | root |              1 |
| ::1       | root |              1 |
+-----------+------+----------------+
3 rows in set (0.00 sec)

mysql> select user(), current_user();
+----------------+----------------+
| user()         | current_user() |
+----------------+----------------+
| root@localhost | root@localhost |
+----------------+----------------+
1 row in set (0.00 sec)

以下是我的设置的屏幕截图：

有什么想法吗？

Answer 1

也许你没有对架构的许可？ 试试这个：

 mysql -u root -p -h 127.0.0.1 -D lp

<强>更新 您可以访问数据库，但您无权访问该模式。

 GRANT ALL ON `lp`.* TO 'root'@'localhost';

Answer 2

其中一些或两个都可以解决您的问题：

检查select host, user, password, Select_priv from mysql.user;的结果。

如果所有行的password字段不相同，请执行以下操作：

SET PASSWORD FOR 'root'@'127.0.0.1' = PASSWORD('123');
SET PASSWORD FOR 'root'@'::1' = PASSWORD('123');

如果所有行的Select_priv不是'Y'，请执行以下操作：

GRANT ALL ON *.* TO 'root'@'127.0.0.1' WITH GRANT OPTION;
GRANT ALL ON *.* TO 'root'@'::1' WITH GRANT OPTION;

修改

由于这些都不是真的，唯一剩下的选择是机器上运行了多个MySQL实例，一个接收通过套接字建立的连接，另一个接收通过TCP建立的连接。
