MongoDB的數據/ DB沒有找到

Question

我給這個路徑進行數據/ DB

/usr/local/Cellar/mongodb/3.2.6/data/db 

接下來的步驟是爲了建立一個綁定到MongoDB的文件夾

sudo mongod --directoryperdb --dbpath /usr/local/Cellar/mongodb/3.2.6/data/db --logpath /usr/local/Cellar/mongodb/3.2.6/log/mongodb.log --logappend -rest 

當初始化須藤mongod的製作在終端出現以下錯誤：

2016-06-08T14:45:06.970+0200 I CONTROL [initandlisten] MongoDB starting : pid=8107 port=27017 dbpath=/data/db 64-bit host=iMac-Krystyna-2.local

你能解釋什麼是錯的，也許顯示一些常見的實踐冰，以便與MongoDB正常工作？

Answer 1

您需要以root身份創建此目錄

要麼需要使用sudo， sudo mkdir -p /data/db

或者您需要做su - 才能成爲超級用戶，然後用mkdir -p /data/db

創建目錄

Answer 2

MongoDB嘗試在系統的根目錄下找到data/db文件夾。嘗試在/ data/db下創建文件夾。
