MongoDB

Basic command

Run MongoDB Community Edition

Follow these steps to run MongoDB Community Edition. These instructions assume that you are using the default settings.

You can run MongoDB as a macOS service using brew, or you can run MongoDB manually as a background process. It is recommended to run MongoDB as a macOS service, as doing so sets the correct system ulimit values automatically (see ulimit settings for more information).

To run MongoDB (i.e. the mongod process) as a macOS service, run:

brew services start mongodb-community@5.0

To stop a mongod running as a macOS service, use the following command as needed:

brew services stop mongodb-community@5.0
