When the rA server is on ur Root u dont need to change anything. Only the ip adress on map, login and char and inter. No bind ip Adress!. The sites available have nothing todo with ur MySQL. If ur MySQL server is on another server u need a few changes otherwise u should everything set back to default. Localhost or 127.0.0.1. Otherwise the rA Server tries to access the MySQL server from outside but its local. And then u need to open port etc. Thats make no sense.
For more clarity about if ur MySQL is on another server:
