回答1:

First try

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

if that does not work then do the following

1. Stop mysqld service with this ( on UNix-like systems)

   sudo mysqld stop

2. Restart it with the --skip-grant-tables option.

3. Connect to the mysql with just: mysql (i.e. no -p option, and username may not be required).

4. Use the following in the mysql client:

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

5. Flush the privileges by running

   FLUSH PRIVILEGES;

6. Remove --skip-grant-tables option. and restart mysqld

7. Finally run

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