错误104442000：用户'@'localhost'对数据库'db'的访问被拒绝

如何解决错误104442000：用户'@'localhost'对数据库'db'的访问被拒绝

不，您应该MysqL -u root -p在bash中运行，而不是在MySQL命令行中运行。如果您使用的是MysqL，则可以输入。

解决方法

我想开始在MySQL中编写查询。

show grants 显示：

+--------------------------------------+
| Grants for @localhost                |
+--------------------------------------+
| GRANT USAGE ON *.* TO ''@'localhost' |
+--------------------------------------+

我没有任何用户ID，但是当我要成为一个用户时，我没有特权，即使我没有一个用户，我也不知道如何授予特权！

mysql> CREATE USER 'parsa'@'localhost' IDENTIFIED BY 'parsa';
ERROR 1227 (42000): Access denied; you need (at least one of) the CREATE USER pr
ivilege(s) for this operation

我试图以root用户身份登录：

mysql> mysql -u root -p;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'mysql
 -u root -p' at line 1
mysql> mysql -u root -p root;
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'mysql
 -u root -p root' at line 1
