Multiple MySQL instances - clean MySQL hostname required

Hi guys,

I have 2 instances of MySQL configured in my linode (one for dev and another for release). MySQL connection string for my dev MySQL instance is mysql:unix_socket=/var/run/mysqld/mysqlddev.sock;dbname= whereas my rel instance simply connects with localhost as my hostname.

Ideally what I want is to have developer friendly connection string for both mysql instances. something like

mysql:host=dev-mysql.mydomainname.com; //for dev instance

mysql:host=rel-mysql.mydomain.com; //for rel instance.

Can anyone help one how I can configure these settings?
