無法使用mongod和mongo啟動MongoDB服務

Question

您好，我的MongoDB存在問題，它工作正常，並且在我重新啟動服務器並顯示了一些錯誤之后。

當我執行命令

$ mongo

它回應

MongoDB shell version: 3.2.13
connecting to: test
2017-05-29T01:11:42.948+0000 W NETWORK  [thread1] Failed to connect to     127.0.0.1:27017, in(checking socket for error after poll), reason: errno:111 Connection refused

exception: connect failed

我也跑了這個命令

$ mongod

它有我這個錯誤信息

***aborting after fassert() failure

然后我嘗試

sudo service mongod start
sudo service mongod status

它給我這個失敗錯誤

我嘗試刪除套接字文件並嘗試一下，但是沒有用。 謝謝高級！ :)

Answer 1

我不確定這是否是正確的答案。 但是，在我看來

2017-05-29T01：17：58.469 + 0000 E NETWORK [initandlisten]無法解除套接字文件/tmp/mongodb-27017.sock errno的鏈接：1 不允許操作

是主要問題。 也許您可以仔細檢查誰擁有這個？ 還可以嗎？

在我的mongo中看起來像這樣：

希望能有所幫助

Answer 2

rm /var/lib/mongodb/mongod.lock
systemctl restart mongod
systemctl status mongod
