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。

对于Windows
而不是
mongodb: / / localhost: 27017 / yourDatabase
写
mongodb: / / yourComputerName: 27017 / yourDatabase
例子:
mongodb: / / Gabriel-Laptop: 27017 /商店
要查找您的计算机/笔记本电脑名称，请在搜索栏中输入“查看您的计算机名称”，“设备名称”附近的名称就是您要查找的名称。
注意:我在某处读到，不建议在Windows操作系统中为MongoDB使用localhost关键字(很可能在这里)。
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:)。
对于我来说:
操作系统:CentOS 7
错误

原因
Mongod不跑
但如果运行mongod，将不会为没有访问权限的工作
解决方案
使用root命令运行mongod
sudo /data/mongodb/bin/mongod --config /data/mongodb/conf/mongodb.conf &
