How to Recover Root Privileges in MySQL Using --skip-grant-tables
In case you accidentally locked yourself out of your MySQL database by revoking root privileges, here's a step-by-step guide to regain access using the --skip-grant-tables option.
Prerequisites:
- You have the MySQL root password.
- You can still log in to MySQL.
Steps:
-
Stop the MySQL Service:
Open the Administrator Tools and go to Services. Locate the MySQL service and stop it.
-
Edit the Configuration File:
Locate the MySQL configuration file (my.ini or my.cnf) on your system. The default locations are:
- Windows: C:Program FilesMySQLMySQL Server 5.5my.ini
- MySQL >= 5.6: C:ProgramDataMySQLMySQL Server 5.6my.ini
-
Add the --skip-grant-tables Option:
In the [mysqld] section of the configuration file, add the following line:
skip-grant-tables
-
Restart the MySQL Service:
Return to the Services window and start the MySQL service again.
-
Log In Without a Password:
Open a command prompt and log in to MySQL. You should now be able to access the database without entering a password.
-
Reset the Root Password (Optional):
If desired, you can reset the root user's password by running the following command:
ALTER USER 'root'@'localhost' IDENTIFIED BY '<new_password>';</new_password>
-
Remove the --skip-grant-tables Option:
Once you have regained access, be sure to remove the --skip-grant-tables option from the configuration file and restart the MySQL service.
