[SOLVED] Installing MongoDB- mongod –config /usr/local/etc/mongod.conf –fork returns: bash: mongod: command not found

Downloading MongoDB
I’m finding it hard to download MongoDB in the background. I’m successful with the command:

brew services start mongodb-community@4.2 ,

but every time i try the command:

mongod –config /usr/local/etc/mongod.conf –fork,

it writes:

bash: mongod: command not found.

The command:

brew services list

works and runs the following:

Name Status User File

mongodb-community@4.2 started myName ~/Library/LaunchAgents/homebrew.mxcl.mongodb-community@4.2.plist

However, when I run:

mongod –config /usr/local/etc/mongod.conf –fork

It writes:

bash: mongod: command not found

Any help?

I am quite new to Computer Science and I only got recently acquainted with the Terminal so be nice!


mongod is not found, /usr/bin/mongod – or wherever it is installed – should work.

Typically when you install a service, then you don’t need to start it.

brew services start mongodb-community@4.2 should be automatically executed when you boot the computer, I think this it at least the default behaviour.

When it runs then you cannot execute mongod --config /usr/local/etc/mongod.conf – you cannot start mongod multiple times (unless you use a different config file with different storage.dbPath and net.port)

In principle brew services start mongodb-community@4.2 and mongod --config /usr/local/etc/mongod.conf are the same. With mongod ... you just get a terminal window staying open, while brew services start runs in background.
