Banalny problem przy instalacji Drupala., Ale nie umiem sobie poradzić. Opcje

[mako241]

Przy instalacji podaję poprawne dane database name, database username, database password. Mimo to otrzymuję komunikat:

Kod

Failed to connect to your MySQL database server. MySQL reports the following message: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2).

* Are you sure you have the correct username and password?
* Are you sure that you have typed the correct database hostname?
* Are you sure that the database server is running?

For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.

Taki sam efekt przy próbie na serwerze nazwa.pl i yoyo.pl.
Sites/default/default.settings.php jest ustawione na ustawione 777.
W czym problem?
