Ubuntu更改mongoDB的位置導致連接失敗（操作不允許）

因此，我已經在Ubuntu上安裝了MongoDB Community Edition，遵循here提供的說明。Ubuntu更改mongoDB的位置導致連接失敗（操作不允許）

我成功測試了我的連接，首先啓動該服務，然後使用任何客戶端進行連接。（robomongo和umongo）。

現在由於我的工作類型，我將存儲GB文件到我的機器。因此我需要改變mongoDB的位置。因此，我採取了以下步驟：（提到here以及）：

步驟1：打開mongod.conf在\etc

步驟2：

編輯路徑deired之一。我的新路徑如下

dbPath: /home/shouman/mongodb

步驟3：複製從舊路徑到新的路徑數據

步驟4：更新新目錄權限遞歸777

現在我似乎無法啓動mongoDB之後。我查了日誌文件，在/var/log/mongodb/mongod.lod而且似乎如下面提到

/home/shouman/mongodb/WiredTiger.wt

現在你可以看到從

MongoDB的幾點注意事項現在看到的新位置是一個權限問題。（這也創造了兩個鎖文件）
我檢查的許可此特定的文件，它似乎確定（檢查在結尾處的畫面）
我試圖重新啓動的MongoDB，但仍同樣的問題

這裏全日誌輸出
