I am setting up Subdomain based MU on my domain.Everything is hosted by me running on one CentOS/Webmin VPS. Will I be better off setting the MySQL user's domain as localhost, 127.0.0.1 or with a wildcard %.mydomain.com? Which is more secure? Is localhost === 127.0.0.1? If not what is the difference?
Also, what is my domain from MySQL's or Wordpress' pov when I am connected by ssh terminal? How about When I connect by Webmin or Usermin? Does MySQL see me as Webmin or my Unix user?
