Unable to connect to database server

If you still have to install Drupal, proceed to the installation page.

If you have already finished installing Drupal, this either means that the username and password information in your settings.php file is incorrect or that we can't connect to the MySQL database server. This could mean your hosting provider's database server is down.

The MySQL error was: No such file or directory.

Currently, the username is cruzricardo and the database server is localhost.

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