如何恢复 MySQL root 用户的完全权限?

2022-01-30 00:00:00 mysql mysql-error-1045 privileges

我不小心删除了我的 MySQL root 用户的一些权限，包括更改表的能力.有什么方法可以将此用户恢复到其原始状态(具有所有权限)?

I accidentally removed some of the privileges from my MySQL root user, including the ability to alter tables. Is there some way I can restore this user to its original state (with all privileges)?

UPDATE mysql.user SET Grant_priv = 'Y', Super_priv = 'Y' WHERE User = 'root';
# MySQL returned an empty result set (i.e. zero rows).
FLUSH PRIVILEGES ;
# MySQL returned an empty result set (i.e. zero rows).


#1045 - Access denied for user 'root'@'localhost' (using password: YES)
GRANT ALL ON *.* TO 'root'@'localhost'

推荐答案

如果 GRANT ALL 不起作用，请尝试:

If the GRANT ALL doesn't work, try:

  1. 停止 mysqld 并使用 --skip-grant-tables 选项重新启动它.
  2. 使用 mysql 连接到 mysqld 服务器(即没有 -p 选项，并且可能不需要用户名).

  3. 在mysql客户端发出如下命令:

  1. Stop mysqld and restart it with the --skip-grant-tables option.
  2. Connect to the mysqld server with just: mysql (i.e. no -p option, and username may not be required).

  3. Issue the following commands in the mysql client:

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';

FLUSH PRIVILEGES;

之后，您应该能够运行 GRANT ALL ON *.* TO 'root'@'localhost'; 并让它工作.

After that, you should be able to run GRANT ALL ON *.* TO 'root'@'localhost'; and have it work.
