mysql - 错误 1044 (42000) : Access denied for user '' @'localhost' to database 'db'

Question

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，但是当我想创建一个用户时，我没有权限，即使我没有一个用户，我也不知道如何创建权限!

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

我尝试以 root 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

Answer 1

不，您应该在 bash 中运行 mysql -u root -p，而不是在 MySQL 命令行中。 如果您在 mysql 中，则可以通过键入 exit 退出。
