  • Open the Terminal app and type brew update.
  • After updating Homebrew brew install mongodb
  • After downloading Mongo, create the “db” directory. This is where the Mongo data files will live. You can create the directory in the default location by running mkdir -p /data/db Make sure that the /data/db directory has the right permissions by running

sudo chown -R id -un /data/db

Enter your password

Run the Mongo daemon, in one of your terminal windows run mongod. This should start the Mongo server. To stop the Mongo daemon hit ctrl-c

While sudo would work as Kanishkah Anwari mentioned, a better practice is to make sure that the user who is starting the monogod instance has write permission to the /data/db folder. Running things in sudo mode can open up other issues in general.

Post back if that doesn't work and we can help trouble shoot further from there.

Hey Ken,

so currently I have to run in one window sudo mongod and then open another window and run mongo in order to the shell to start.. How would I go about automating that process? I use to be able to run mongo and the shell would start automatically from my user.. but for some reason maybe an update I can not do that.

I'm sure you could write a bash script or something that would allow you to type something akin to start-mongo and the script would start the mongod instance then launch a new terminal window with mongoshell running.

Depending on your use case, MongoDB's recommended best practice at this point is to use MongoDB Atlas as it is much easier to work with than having to manage your own servers. Atlas, as a product, was released after the Treehouse content was produced so it was never shown as an option.

Feel free to reach out directly if you'd like to learn more about Atlas.
