Why Am I Getting \'Access Denied for User\' in MySQL?

MySQL: Resolving "Access Denied for User" Error

While creating and granting privileges to a new MySQL user, you may encounter the error "Access denied for user". This issue arises when the user does not have appropriate privileges or is attempting to connect to the database from an unauthorized location.

To troubleshoot this error, start by verifying the grant statement. Ensure that you provide the correct username and that you are granting privileges on the specific database and tables that the user needs to access. For example, instead of using "GRANT ALL ON .", you may grant only the necessary privileges on the specific tables or schema, such as:

GRANT SELECT, INSERT, UPDATE, DELETE ON servname_shbusers.* TO 'servname_shb'@'localhost';

Additionally, ensure that the user is attempting to connect to the database from a permitted host. By default, MySQL restricts user access to localhost. If the user is trying to connect from a different hostname or IP address, you need to grant them privileges explicitly for that host, as seen below:

GRANT ALL ON *.* TO 'servname_shb'@'remote-host';

Once you have corrected the grant statement and verified the connection host, remember to flush the privileges using the command:

FLUSH PRIVILEGES;

This ensures that the new privileges take effect immediately.

If the error persists, check if the user's password has expired. You can reset the password using the following statement:

ALTER USER 'servname_shb'@'localhost' IDENTIFIED BY 'new_password';

Remember, when handling MySQL privileges, it is crucial to grant only the necessary permissions to limit potential security risks.
