mongodb - 无法与 MongoDB 连接

Question

我在与 mongo 连接时遇到问题。

me@the_host:~$ mongo

MongoDB shell version v4.0.0
connecting to: mongodb://127.0.0.1:27017
2018-06-28T17:06:37.445+0200 E QUERY    [js] 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:251:13
@(connect):1:6
exception: connect failed

我去看了/var/log/mongodb/mongod.log：

2018-06-28T17:16:11.763+0200 I COMMAND  [initandlisten] Assigning UUID b237b94b-b3a3-4ba1-9c39-c87d6f3555db to collection local.startup_log

2018-06-28T17:16:11.764+0200 F -        [initandlisten]

我执行mongod --journalOptions 4然后mongod --repair，但错误仍然相同。我不知道下一步该怎么做。。

之前克服过这个问题的任何人都可以指出正确的方向吗？
