Why Can\'t I Access My MySQL Database After Resetting the Root Password?

Resolving MySQL Root Password Reset Issues after Failed Login

Changing your MySQL root password should be a straightforward process, but sometimes, unexpected difficulties can arise.

Troubleshooting Steps

According to your query, you've attempted common reset methods like using mysqld_safe --skip-grant-tables, updating the root password, and verifying the user table. Yet, you're still facing access denied errors when logging in with the new password.

Solution

In such cases, consider the following:

1. Execute the Following Queries:

   SET PASSWORD FOR 'root'@'localhost' = PASSWORD('mypass');
   FLUSH PRIVILEGES;

   This will explicitly set the password for the root user and flush the privilege tables, ensuring the password change is reflected.

2. Disable MySQL Anonymous User:

   If the above method doesn't resolve the issue, check whether an anonymous user (with no username or password) is enabled. You can disable it by adding skip-name-resolve to your MySQL configuration file (my.cnf).

3. Change Password from Unix Shell:

   Connect to MySQL using the user interface, but without starting the MySQL daemon. Then, issue the SET PASSWORD query as follows:

   mysql -u root --skip-password
   SET PASSWORD FOR 'root'@'localhost' = PASSWORD('mypass');
   FLUSH PRIVILEGES;
   systemctl restart mysql

4. Uninstall and Reinstall MySQL:

   If all else fails, consider uninstalling and reinstalling MySQL to ensure a clean state. After reinstalling, follow the reset password steps meticulously and check if the issue persists.

By implementing these troubleshooting measures, you can resolve any remaining issues and regain access to your MySQL database with the updated root password.
