In the troubleshooting section, the manual states that the problem is permissions, and that:

GRANT ALL PRIVILEGES ON [dbname].* to '[user]'@'[hostname]' identified by '[password]';

will solve the problem. A note also indicates that "Redhat linux is broken..."

and that the hostname should be "localhost.localdomain"

Thus, the following command:

GRANT ALL PRIVILEGES ON nyhos.* TO 'mysql@localhost.localdomain' identified by
'passwd';

would seem to be the command,
