尝试修复root mysql用户权限

Question

第一步是关闭 MySQL，然后在禁用显示授权的情况下重新连接：

/Applications/MAMP/Library/bin/mysqld --skip-grant-tables
--skip-networking --port=3306 --socket=/Applications/MAMP/tmp/mysql/mysql.sock &

从那里我连接到没有用户/密码的 MySQL 并修复了授予权限：

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

所以现在我的 mysql.user 行看起来像：

然后我关闭了 mysql 并在没有授权表选项等的情况下重新启动：

/Applications/MAMP/Library/bin/mysqld --port=3306 --socket=/Applications/MAMP/tmp/mysql/mysql.sock &

然后我用 root 用户和密码重新连接，并再次授予自己对所有本地数据库的权限：

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost'

还是没有运气。

mysql> SELECT * FROM exp_throttle LIMIT 1;
ERROR 1142 (42000): SELECT command denied to user 'root'@'localhost' for table 'exp_throttle'

我是否遗漏了一些明显的东西？

Answer 1

更新查询后你需要刷新权限

FLUSH PRIVILEGES;

为了阐明您可以运行的权限

SELECT user()
SELECT current_user()

在这两种情况下都应该有 root@localhost。然后看看你目前的赠款

SHOW GRANTS;

如果在安全模式下恢复权限没有帮助，请尝试添加另一个具有完全权限的用户并使用新用户连接到数据库。
