MongoDB一次又一次地往下走

Question

我在mongodb與spring-data之間使用multi-tenancy，在Authentication之後用admin數據庫連接多個數據。每過幾個小時後，mongod服務就會停止。我得到以下日誌，而其關閉：

感謝提前:)

Answer 1

關鍵是使用​​信號運行後臺進程。

Answer 2

2017-01-17T18：17：36.871 + 0000我CONTROL [signalProcessingThread]有 信號2（中斷） ，將在當前cmd結束後終止

您得到了一個SIGINT（「got signal 2（Interrupt）」），當按CTRL + C來「中斷」進程時會發生這種情況。你如何開始mongod過程？它是否在後臺運行？
