Install with Homebrew

brew install mongodb

Set up launchctl to auto start mongod

$ ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents

/usr/local/opt/mongodb/ is a symlink to /usr/local/Cellar/mongodb/x.y.z (e.g., 2.4.9)

Edit: also works with Ubuntu Server 16.04

1 Install dkms. From the guest run:

    sudo apt-get install dkms

Mac OS X 10.10 Yosemite

Custom recipe to get OS X 10.10 Yosemite running from scratch, setup applications and developer environment. I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.

This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.

You are encouraged to fork this and modify it to your heart's content to match your own needs.
