Step $3$: Configure the Web Application $1.$ In order properly configure the web application, you must determine the internal IP address of the SQL Server instance. Open another PuTTY session to your database host and enter the following command: ip addr You will receive output like below. You want to look for device eth$0$ and get the IP address from the inet line. It should start with $172($and not $127$; that is loopback$).2.$ Back on your webserver instance in a text editor of your choice, edit the config.php file. Two changes need to be made: a$.$ Change the value of DATABASE$\_$SERVER$\_$IP$\_$ADDRESS$\_$HERE to the IP address you found in the previous step. b$.$ Change the value of SQL$\_$SERVER$\_$PASSWORD$\_$HERE to the value of your SQL Server Password you set up in a previous milestone
