Why Am I Getting Access Denied Errors After Changing My MySQL Root Password?

MySQL Root Password Change: Resolving Access Denied Errors

Changing the MySQL root password should be a straightforward process, but it can sometimes result in Access denied errors when attempting to log in. This article addresses specific troubleshooting steps to resolve this issue:

Issue Description

Despite following the recommended steps of executing mysqld_safe --skip-grant-tables, updating the root password, and verifying its presence in the user table, users encounter Access denied errors upon attempting to log in with the new password. This issue persists even after removing and reinstalling MySQL.

Solution

To resolve this problem, execute the following commands in the MySQL shell:

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

The first command updates the root user's password on localhost to 'mypass'. The second command flushes the privileges table to ensure the changes take effect immediately.

Explanation

The error messages indicate that the new root password is not being recognized. This can occur if the initial password update did not propagate correctly or if there are additional configuration or permission issues.

By executing the commands above, you explicitly set the root user's password on localhost and then refresh the privileges table. This ensures that MySQL recognizes the updated password and grants the appropriate permissions.

Additional Notes

• Replace 'mypass' with your desired root password.
• If you are using a different hostname or bind-address, specify it accordingly in the command.
• After executing these commands, restart the MySQL daemon to apply the changes.
