I think so. I thought sometimes you need to do localhost.localdomain but I can’t recall when that was the case.

If you are going to copy over the bb-config-sample.php to bb-config.php, you need to insert the proper values in the file. Otherwise, the config file is invalid, as it’s telling you right here.
