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             | 127.0.0.1       |
| debian-sys-maint | localhost       |
| jack             | localhost       |
| root             | localhost       |
| root             | russ-elite-book |
+------------------+-----------------+
5 rows in set (0.00 sec)

mysql> delete from user where user = 'jack';
Query OK, 1 row affected (0.00 sec)

mysql> select user,host from user;

当前回答

mysql> DELETE FROM mysql.db WHERE user = 'jack'

重启服务器:

# mysql。服务器重启

然后执行CREATE USER命令。

其他回答

我也犯了同样的错误。但是命令“FLUSH PRIVILEGES;”不起作用。我喜欢这样:

CREATE USER 'jimmy'@'localhost' IDENTIFIED BY 'test123';
UPDATE mysql.user SET USER='jack' WHERE USER='jimmy';

这篇文章MySQL错误1045(28000):访问拒绝用户'账单'@'localhost'(使用密码:YES)是有用的。有时，会有匿名用户“@‘localhost’”或“@‘127.0.0.1’”。为了解决这个问题，

首先删除“创建用户”失败的用户。创建新用户。向新用户授予所需的特权。冲洗的特权。

如果你在mysql上使用DELETE语句。如果试图删除一个用户，然后尝试用CREATE user重新建立用户，将会得到一个1396错误。通过运行DROP USER 'username'@'host'来摆脱这个错误;

DELETE 
  FROM mysql.user 
 WHERE user = 'jack';

(你会得到1396个错误，如果你试图重新创建杰克)

CREATE USER 'jack'@'localhost' IDENTIFIED BY PASSWORD '*Fi47ytFF3CD5B14E7EjkjkkC1D3F8086A5C0-krn';

(通过运行DROP USER来摆脱这种情况)

DROP USER 'jack'@'localhost';

(我想FLUSH特权不会造成伤害，但肯定会先放弃用户。)

two method 
one :
setp 1: drop user 'jack'@'localhost';
setp 2: create user 'jack'@localhost identified by 'ddd';

two:
setp 1: delete from user where user='jack'and host='localhost';
setp 2: flush privileges;
setp 3: create user 'jack'@'localhost' identified by 'ddd';
