How to Resolve the \'SQLSTATE[HY000] [1045] Access Denied\' Error in MySQL?

Investigating "SQLSTATE[HY000] [1045] Access Denied" Error

Cause:

The access denied error occurs when the provided credentials for database connection are incorrect or insufficient. In the given case, the error message indicates that the user 'test2' with host 'localhost' is denied access.

Solution:

1. Verify User Existence: Execute the following query to confirm if the user 'test2' exists for the given host 'localhost':

SELECT user, host FROM mysql.user

2. Check Matching Host: Ensure that the host specified in the CakePHP configuration matches the host associated with the MySQL user. If the host is set to '%', change it to 'localhost'.
3. Reset Password if Necessary: If the user exists, reset the password using the following command:

SET PASSWORD FOR 'test2'@'localhost' = PASSWORD('mysecretcleartextpassword')

4. Grant Database Privileges: Grant the necessary privileges to the user on the jobs database:

GRANT SELECT ON jobs.* TO 'test2'@'localhost'

5. Flush Privileges: Force MySQL to re-read the privilege tables:

FLUSH PRIVILEGES

Additional Considerations:

• Ensure that the MySQL server has the right firewall rules in place.
• If running on WAMP, check if the WAMP server is configured to listen on port 3306.
• Verify that you are using the correct MySQL version supported by CakePHP.
