linux - linux(ubuntu)上的mongod命令吐出随机消息

Question

linux(ubuntu) 上的 mongod 命令吐出随机消息，mongo 拒绝连接 127.0.0.1:27017
终端消息

随后在终端 上运行 mongo 时(我在不同的终端窗口上运行此命令)

MongoDB shell version v4.4.0
connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb
Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed: SocketException: Error connecting to 127.0.0.1:27017 :: caused by :: Connection refused :
connect@src/mongo/shell/mongo.js:362:17
@(connect):2:6
exception: connect failed
exiting with code 1

我的mongodb版本是

db version v4.4.0

    "version": "4.4.0",
    "gitVersion": "563487e100c4215e2dce98d0af2a6a5a2d67c5cf",

    }
}```

我遇到了同样的问题。删除/tmp/mongodb-27017.sock 应该修复它。
您可以在日志中看到它无法删除它:

{
  "t": {
    "$date": "2020-08-20T22:33:58.006+05:30"
  },
  "s": "E",
  "c": "NETWORK",
  "id": 23024,
  "ctx": "initandlisten",
  "msg": "Failed to unlink socket file",
  "attr": {
    "path": "/tmp/mongodb-27017.sock",
    "error": "Operation not permitted"
  }
}
