it seems to me it’s not forbidden to do the following. Have Tab #1 open in your browser to very carefully study the one lecture right before your Lab in question. That lecture - like most - have a “lecture notes” part down below the embedded lecture video where you can find examples of the important files with some brief commenting where they should fit into the process in question.
Let that Tab #1 stay open, and put the following Lab next to Tab #1 in a Tab #2 in your browser. That way you can match the successive points of question in your Lab in Tab #2 with the files in Tab #1.
In my opinion you can see the Labs as a matching exercise, where you often have to match the given questions (in your Tab #2) with example config files and instructions (in your Tab #1), you know?
That said, let’s go back to your questions here. First, you absolutely need to fill in the given
mongod.conf file. Copy over its ingredients from Tab #1 and then carefully match its entries with the terms in the Lab question. Do a
cat mongod.conf in the IDE terminal below to double-check.
mongo -f mongod.conf to start the daemon. Do
ps ef | grep mongod to double-check.
Then connect to
mongod process via
mongo shell. Do
> db you might get
test then do
> show dbs to double-check you are in the right place. And so forth.
Hope you can move forward, Regards, M.
