问题描述
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:
- 停止
mysqld并使用--skip-grant-tables选项重新启动它. - 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). 在mysql客户端发出如下命令:
- Stop
mysqldand restart it with the--skip-grant-tablesoption. - Connect to the
mysqldserver with just:mysql(i.e. no-poption, and username may not be required). 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.
