That opened up MySQL in the command line, if that’s what it was supposed to do.
I don’t have a wp-config.php file, only wp-config.php. I believe the configuration process through the browser should create the non sample file. I tried creating it myself and putting in the relevant information. However, when I tried to connect through the browser I was just met by a white screen with black writing at the top saying that it couldn’t connect to the database.
