错误1044(42000):用户'@'localhost'对数据库'db'的访问被拒绝 [英] ERROR 1044 (42000): Access denied for user ''@'localhost' to database 'db'

问题描述

我想开始用MySQL编写查询.

I want to begin writing queries in MySQL.

show grants显示:

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

我没有任何用户ID，但是当我想让一个用户没有特权时，即使我没有一个用户，我也不知道如何授予特权！

I do not have any user-id but when I want to make a user I don't have privilleges, also I don't know how to make privileges when even I don't have one user!

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用户身份登录:

I tried to sign in as root:

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

推荐答案

否，您应该在bash中运行mysql -u root -p，而不是在MySQL命令行上运行. 如果您使用的是mysql，则可以通过输入 exit 退出.

No, you should run mysql -u root -p in bash, not at the MySQL command-line. If you are in mysql, you can exit by typing exit.
