allora..ho creato sia l'utente mysql ke il gruppo..ora se da root faccio ./mysql start ho

codice:
linux:/etc/init.d # ./mysql
Usage: ./mysql {start|stop|status|reload|restart|try-restart|force-reload}
linux:/etc/init.d # ./mysql start
Creating MySQL privilege database and starting MySQL...
hostname: Unknown host
Neither host '' and 'localhost' could not be looked up with
/usr/bin/resolveip
Please configure the 'hostname' command to return a correct hostname.
If you want to solve this at a later stage, restart this script with
the --force option
                                                                     failed
linux:/etc/init.d #
ho il presentimento ke devo modificare qlks..ma cosa?anzi..devo modificare l'hostname ma dove?
