mongodb的默認db路徑是/data/db/。

所以，當你運行：

mongod

MongoDB的檢查/數據/ DB /存在，並且如果用戶訪問它。在你的情況下，沒有這樣的目錄，因此錯誤。

但是，您可以使用mongod的--dbpath參數（或使用配置文件）覆蓋默認數據庫路徑。

mongod --dbpath /var/lib/mongodb/data/db

在這種情況下，而不是檢查/數據/分貝/ MongoDB的檢查/ var/lib中/ mongodb的/數據/分貝。你的情況，你有指定的目錄，你有權訪問它，因此它運行。

而這樣做並不能啓動mongo shell。要啓動shell，首先如上所述啓動mongod並保持運行。然後在另一個終端執行

mongo

這將啓動mongo shell。

它不運行，但它仍然退出，如果你在框中向下滾動 – Sammaye

@Sammaye：它看起來像mongod啓動成功，當他使用--dbpath選項。 – 4J41

哦，確定它沒有，文本的最後一個塊有他運行兩個命令 – Sammaye

當我從創建數據/ db目錄將解決您的問題，這個問題看。

創建它，然後像這樣添加，如果你有C盤中的目錄路徑。

mongod --dbpath "c://data/db"

設置DBPATH後，你應該開始MongoDB的是服務。

sudo service mongodb start
