node.js - MongoDB - 无法连接到 127.0.0.1 :27017, 原因:errno:111 连接被拒绝

Question

我以前遇到过这个问题，通过重新启动 mongo 解决了:

$ sudo systemctl start mongodb

但是我又遇到了这个问题，我尝试像以前一样重新启动它。但这次不行了!

$ mongo
MongoDB shell version: 3.2.6
connecting to: test
2017-03-29T10:48:44.306+0100 W NETWORK  [thread1] Failed to connect to 127.0.0.1:27017, reason: errno:111 Connection refused
2017-03-29T10:48:44.307+0100 E QUERY    [thread1] Error: couldn't connect to server 127.0.0.1:27017, connection attempt failed :
connect@src/mongo/shell/mongo.js:229:14
@(connect):1:6

exception: connect failed

我也尝试过:

1) 删除.lock文件

sudo rm /var/lib/mongodb/mongod.lock 

2)修复mongodb

mongod –repair

3)启动mongodb

$ sudo systemctl start mongodb

4)启动mongo客户端

$ mongo

... i get the same error above!

你知道我还能做什么吗？

我使用 brew 重新启动了 mongodb 服务，它有所帮助:

brew services stop mongodb
brew services start mongodb
