インストール
Homebrewでインストール
brew install mongodb

==> Caveats
To have launchd start mongodb at login:
ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
Then to load mongodb now:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
Or, if you don't want/need launchctl, you can just run:
mongod
/usr/local/Cellar/mongodb/2.2.2-x86_64: 20 files, 170M, built in 98 seconds
上にあるようにログイン時に起動してロードするには
ln -sfv /usr/local/opt/mongodb/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
起動
mongod
接続
mongo
