I recently setup a MySQL server and encounted the following error when I ran the mysql console (and incidentally the administrator GUI tool):
ERROR 1045: Access denied for user: 'root@localhost' (Using password: YES)
I had done a standard installation and reached the last page in the configuration wizard when the security check stage failed with an error suggesting that the MySQL port was blocked by a firewall.
closed the wizard, checked there was no firewall running and then and tried running mysql and the administrator GUI and found the same error in both cases.
Can anyone suggest a solution to the problem or perhaps resources for diagnosing MySQL problems.
