mongoDB可以啟動，但是無法啟動mongo shell？

Question

運行mongod指令，可以啟動mongoDB

這應該算是成功了吧？

但是運行mongo的話，終端會報出這樣的錯誤：

MongoDB shell version: 3.2.7
connecting to: test
2017-01-31T12:56:00.745+0800 W NETWORK  [thread1] Failed to connect to 127.0.0.1:27017, reason: errno:61 Connection refused
2017-01-31T12:56:00.745+0800 E QUERY    [thread1] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed :
connect@src/mongo/shell/mongo.js:229:14
@(connect):1:6

exception: connect failed

不知道是為什麼~求教，謝謝！

MongoDB是用homebrew裝的？
是的話先launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mongodb.plist
然後運行mongod
