错误1396 (HY000):为'jack'@'localhost'创建用户操作失败

我似乎无法重新创建一个我已经删除的简单用户，即使是MySQL的根用户。

我的案例:用户'jack'之前存在，但我从mysql中删除了它。用户才能重新创建它。我在那张桌子上没看到这东西的痕迹。如果我对其他一些随机用户名执行这个命令，比如'jimmy'，它就能正常工作(就像它最初对'jack'所做的那样)。

我做了什么破坏用户'jack'，我如何撤销这个破坏，以重新创建'jack'作为MySQL安装的有效用户?

参见下面的示例。(当然，最初，jack这个词从被创造到被移除之间有很长一段时间。)

mysql> CREATE USER 'jack'@'localhost' IDENTIFIED BY 'test123';
Query OK, 0 rows affected (0.00 sec)

mysql> select user,host from user;
+------------------+-----------------+
| user             | host            |

| root             | russ-elite-book |

我的经验与这个错误导致我做显式删除mysql。用户，但不是从mysql.db

如果create中的用户名存在于user或db中，就会得到这个错误。通过做从mysql删除。user == 'user@bar'; delete from mysql.db where User == 'user@bar';

在MySQL 5.6中使用Drop user userid;不管用。使用方法:删除用户userid @ localhost;和/或删除用户'userid'@'%';通过这种方式，我可以删除用户并重新创建它。

一个简单的工作围绕这个问题。由于“delete”命令只是删除mysql数据库“user”表中的用户记录，我们可以将其重新添加，然后完全删除该用户。然后可以创建同名用户。

步骤1。在mysql数据库中查找用户表的记录格式

use mysql;
select * from user;

步骤2。根据步骤1中显示的列，使用用户名创建一个虚拟记录。将其插入到表中，例如，提醒将“用户名”替换为您的用户名。

Insert into user value ('%','username','N','N','N','N','N',
'N','N','N','N','N','N','N','N','N','N','N','N','N','N','N',
'N','N','N','N','N','N','N','N','N','','','','','0','0','0',
'0','mysql_native_password',
'*52C5E3AC6BC5E2E0BFF86978BF62A1481AC79D58','N',
'2016-12-10 23:59:12',null,'N');

注意:有时您可能会在插入时遇到问题，只需更改数据即可使其工作。

步骤3。删除该用户。

drop user username;

现在您可以创建具有相同名称的用户。
