這幾天一直在折騰mongodb數據庫，一直出現如下這個問題
MongoDB shell version v3.6.0 connecting to: mongodb://127.0.0.1:27017 2017-12-27T09:54:34.775+0800 W NETWORK [thread1] Failed to connect to 127.0.0.1:27017, in(checking socket for error after poll), reason: Connection refused 2017-12-27T09:54:34.778+0800 E QUERY [thread1] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed : connect@src/mongo/shell/mongo.js:237:13 @(connect):1:6 exception: connect failed
嘗試各種方法都不行
當mongodb service 沒有運行的時候會發生這樣的錯誤
嘗試了新建一個/data/db 目錄，也不奏效。
后來通過搜索，尋找到來解決方法，運行命令
brew services start mongodb
再去調用數據庫命令
mongo
就可以完美解決問題了
最終mac下顯示成功的提示
