Node.js MongoDB-无法连接到127.0.0.1:27017，原因：错误号：111连接被拒绝,node.js,mongodb,express,Node.js,Mongodb,Express,我以前遇到过此问题，通过重新启动mongo解决了此问题： $ sudo systemctl start mongodb 但是我又遇到了这个问题，我试着像以前一样重新开始。但是这次不行了 $ 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: err

我以前遇到过此问题，通过重新启动mongo解决了此问题：

$ sudo systemctl start mongodb

但是我又遇到了这个问题，我试着像以前一样重新开始。但是这次不行了

$ mongo

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

$ sudo systemctl start mongodb

3）启动mongodb

mongod –repair

$ 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，它帮助：

brew services stop mongodb
brew services start mongodb

请尝试

sudo systemctl status mongodb.service

，这可能会让您更好地了解它崩溃的原因：）@georoot谢谢。请看我的编辑上面。你能看到是什么引起的吗？

——quiet

标志正在抑制错误。直接从终端运行

mongod

，命令是

mongod--config/etc/mongodb.conf

@georoot对不起，我不明白现在该怎么办。使用什么？当我运行

$sudomongod--config/etc/mongodb.conf时，我没有得到任何回报。
