In attempting to config FC pipes I've run in to the fact that my host provides no sql socket. To my request for socket info they replied: "You won't be using the socket method to connect, you'll be giving it the hostname.
Any web application needs to access the MySQL server through that host name, not a local socket. In your WordPress configuration file, for example, the variable to set would be 'DB_HOST' and you should use the host name."
Please advise for using DB_HOST to config FC pipes, instead of MYSQL_SOCKET.
