For QA_MYSQL_HOSTNAME, try '127.0.0.1' or 'localhost' if MySQL is on the same server.
For persistent connections, set the QA_PERSISTENT_CONN_DB at the bottom of this file; do NOT
prepend the hostname with 'p:'.
If you are using port number other than default (3306), add the port number after host name.
e.g. 127.0.0.1:3307
