我的 mongodb 版本是 2.6.12
忽然無法使用
錯誤訊息如下

MongoDB shell version: 2.6.12
connecting to: test
2020-09-28T09:15:31.869+0800 warning: Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2020-09-28T09:15:31.870+0800 Error: couldn't connect to server 127.0.0.1:27017 (127.0.0.1), connection attempt failed at src/mongo/shell/mongo.js:146
exception: connect failed

請問各位高手有什麼想法，因為沒法使用好像也不能用備份指令先備出來
還是說我看 mongo 的資料夾中有 dbname.0 和 dbname.ns 這兩個檔案可以直接下載下來重新安裝 mongo 後貼回來就能用了

看更多先前的討論...收起先前的討論...

你的mongodb啟動了嗎
也有可能你的mongodb使用不當讓它掛掉需要重啟

有趣的是 service mongod restart 是成功的
Starting mongod (via systemctl): [ OK ]
但是
service mongod status
