我昨天保存了数据，但是当我尝试通过命令提示符打开MongoDB并触发命令mongod时，它会抛出以下消息

我确保我的数据路径正确，但是无法解决此问题。

Answer 1

尝试以下方法：

Mac: Documents/mongodb/bin/mongod --dbpath Documents/data/db/
Window: "C:\Program Files\MongoDB\Server\3.6\bin\mongod.exe" --dbpath d:\test\mongodb\data

您只需要设置db路径即可。

您可以将存储db路径设置为配置文件：Check this

和check this用于窗口安装。

Answer 2

如果您使用的是Linux，只需增加存储文件的权限并重新启动mongodb，它将起作用。默认存储文件为var / lib / mongodb。要增加权限，请使用：chmod 777 mongod。

MongoDB关闭，代码为：12
