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;
+------------------+-----------------+

似乎您需要为数据库创建用户，并为创建的用户授予特权

——>为数据库创建用户

CREATE  USER <'username'>@'%'IDENTIFIED BY <'password'>;

创建用户“root”@“%”，用户名为“root”;

——>授予特权

FLUSH PRIVILEGES;
GRANT ALL PRIVILEGES ON <db name>.* TO '<username>'@'%';

授予mydb上的所有特权。*到“root”@“%”;

其他回答

您不应该以这种方式手动删除用户。MySQL有REVOKE语法用来删除权限，DROP USER语法用来删除权限:

REVOKE priv1,priv2,priv3,etc... FROM 'jack@localhost'; // remove certain privileges
DROP USER 'jack@localhost'; // completely delete the account

最好使用提供的工具，而不是在后台瞎忙活。

MySql的错误解决:错误码1396

Whenever you had try to run query which create a User as Shown Below. MySql> CREATE USER 'springstudent'@'localhost' IDENTIFIED BY 'springstudent'; GRANT ALL PRIVILEGES ON * . * TO 'springstudent'@'localhost'; But when you try to run query which create user within all previleges, Due to bug it create gives previleges without showing user Because of this Problem we need to use this script for flush priviledges MySql> drop user 'springstudent'@'localhost'; flush privileges; create user admin@localhost identified by 'admins_password' After deleting the user, there is need to flush the mysql privileges Then Create User again

Gotchaaa ....Solved ....

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;

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。

我知道这是旧的，但因为这是谷歌的第一个结果，我想我应该添加我的解决方案。在我的情况下，删除用户工作得很好，但重新创建用户给了我一个“错误2013 (HY000):在查询期间失去与MySQL服务器的连接”和“错误2006 (HY000): MySQL服务器已经离开”。我尝试了flush特权->删除用户解决方案，但仍然有相同的错误。

在我的情况下，这个错误是由于mysql从5.1升级到> 5.6。查看错误日志，我注意到它说要运行mysql_upgrade。这样做，我的创建用户语句工作良好!
