It sounds like you may have an instance sitting around from a previous install, or somesuch.
ps auxww | grep sql | grep logger.
Kill it (make sure it's the logger instance, not the other one).
Try restarting, see if you can get in then.
If not, you can try resetting the password with zmlogmypasswd, but if the root sql passwd is out of sync, that won't work - you'll have to restart the instance with --skip-grant-tables (that's your search term, btw) and set it manually. |
