无法连接到服务器127.0.0.1:27017

我来自riak和redis，在那里我从未有过这个服务启动或互动的问题。

这是蒙古人普遍存在的问题，我对此一无所知。重启也无济于事。我是蒙哥的新手。

mongo
MongoDB shell version: 2.2.1
connecting to: test
Fri Nov  9 16:44:06 Error: couldn't connect to server 127.0.0.1:27017 src/mongo/shell/mongo.js:91
exception: connect failed

这是我在日志里看到的。

我在ubuntu上得到这个错误，但你可以尝试以下命令:

sudo service mongod start

我是一个windows用户，我在2018年11月安装了MongoDB，我不想设置数据/db目录。但是过了几天，当我打开的时候，收到了一条错误信息:

MongoDB shell version v4.0.4
connecting to: mongodb://127.0.0.1:27017
2018-12-05T20:42:40.108+0530 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 :: No connection could be made because the target machine actively refused it. :
connect@src/mongo/shell/mongo.js:257:13
@(connect):1:6
exception: connect failed

然后我试图修复使用所有上述答案，没有工作。当我试着运行mongod时，它说

MongoDB starting : pid=12220 port=27017 dbpath=C:\data\db\ 64-bit host=bla

我试图通过文件系统和cmd改变db路径(到程序文件)，但这些都不起作用。

对我有效的解决方法是:

打开任务管理器(ctrl + shift + esc) -> Services选项卡，有一个状态为stopped的MongoDB行。然后我右键单击开始，一切都工作得很完美:)。

如果以上方法都不奏效:进入service (start>search>services)，启动mongodb服务。然后，在cmd提示符中，进入bin后，键入:/>mongo

错误:无法连接到127.0.0.1:27017服务器，连接尝试失败:SocketException:错误连接到127.0.0.1:27017::导致::没有连接可以建立，因为目标机器主动拒绝它。

这个错误是因为Mongo服务器被关闭

遵循以下步骤

打开任务管理器进入>服务找到MongoDB 右键单击并选择Start

我也有同样的问题，我已经删除了E:\Mongo Data Files\db\mongod。锁文件，所以它开始工作。该问题是由于服务器不适当的关闭。所以锁文件不干净。
