What SQL settings should I use?

First, HCS runs a useful tool called phpMyAdmin at https://www.hcs.harvard.edu/phpmyadmin/. You can view and modify many of your database settings here. You can also access your MySQL database from the command line by typing

mysql -h mysql.hcs.harvard.edu -u group-name_here -p

at the command prompt. Enter your MySQL password when prompted.

Some settings you would use in connecting to the database in a php script:

DB = group_name
DBUSER = group_name (same)
DBPASS = your_mysql_password
DBSERVER = mysql.hcs.harvard.edu
