我的設置和我的Mac OS X的安裝MongoDB的我現在能得到它的使用下面的命令開始的MongoDB不使用sudo的Mac OS X
sudo mongod
雖然，當我嘗試才能正確運行與mongod命令運行服務器我得到下面的輸出

BTW，我沒有運行的另一蒙戈實例，我sudo ps -ef | grep mongo檢查它。我怎樣才能讓MongoDB啓動並運行，而不必每次都使用sudo命令呢？我知道濫用sudo會帶來未來可能的泄漏。
大概的文件已經全部由「根」所擁有。如果你刪除它們並在你自己的用戶下運行，那麼這將很好。當然，在任何**體系結構中，「推薦」實際運行在「不同」和「非特權」用戶帳戶下。 –
更不用說「你已經有一個實例在運行」。因此，如果沒有指定另一個目錄，則默認設置將失敗，因爲使用 –
提供的同一位置和相同端口將失敗。並且「警告：soft rlimits太低。文件數量爲256，應該至少爲1000」以root身份運行的進程可以改變自身的軟限制，任何其他用戶都不能。 – msw
