MySql Access Denied

aboboras has asked for the wisdom of the Perl Monks concerning the following question:

I'm deplying a server and can't connect to MySql with Perl. I receive the error "Access denied for user 'root'@'localhost' (using password: YES)"

On my users table i have root with all privileges at localhost and also at '%'(any host). I can access the database under 'root' user from the linux shell but with Perl script it does not work.

$dbh = DBI->connect ("DBI:mysql:host=localhost;database=mydb", "root", "mypass", {PrintError => 0, RaiseError => 1});

Also, do not allow your application to connect to the database as a rootly user, lest you run afoul of The Bobby Tables problem. (Yes, you would be astounded at just how many web-apps are out there, available to the general public, which do have the authority to issue a `DROP TABLE` command! Or, heh heh, `GRANT ALL PRIVILEGES TO ...`) Your application should connect with one or more application-specific IDs which practice the “principle of least privilege.” The MySQL system should be configured to consider, not only the user-name but also the IP-address that is making the connection. Each and every user-id should allow only the least amount of access required to do the job at hand, and, where possible, more than one such id should be used as appropriate. You may as well start dealing with these issues now.
