The goal of this exercise is - when you run curl http://127.0.0.1/ in the terminal you get My name is <name> and my ID is <id> (do not display both names) with HTTP response code 200. This exercise is a mix of system and service troubleshooting.
Run the curl command in verbose mode and see what the output looks like.
What is MySQL?
Find out where the MySQL configuration and log files live. What do the configuration options mean?
ETA - this exercise shouldn’t take more than 3-4 days. If you are stuck, please ask for help.
While you are doing the exercise, I would really recommend logging somewhere the commands you run and noting what information that gives you and whether or not that was helpful in reaching the end goal which is displaying the data from MySQL.
