Creating a MongoDB database

First create a directory for the database and set permissions:

$ mkdir /data/db
$ sudo chown -R `id -un` /data/db

Then start the Mongo daemon

mongod

This will run continuously in the terminal and should say somewhere that it is waiting for connections on port 27017. This command must be executed before you run any backend that interacts with the Mongo database.

MongoDB Compass

Compass is a graphical interface for viewing and interacting with the data in your Mongo database. It will automatically load to the default Mongo port: 27017.

Arch Linux troubleshooting

Most times any problems will be a result of a Mongo process that is already running. Resolve with:

# Kill running Mongo process...
# Identify PID
sudo lsof -iTCP -sTCP:LISTEN -n -P
sudo kill [pid]

Otherwise try the below.

# Check that the systemd service is runnign for Mongo
sudo systemctl status mongodb

# If not, enable and start service (only need to do this once for machine)
sudo systemctl enable --now mongodb
sudo systemctl start --now mongodb

# If issues with Mongo daemon...
# Remove the current socket
rm /tmp/mongodb-27017.sock

For additional command line utilities you will also need to install mongodb-tools from the AUR.
