我正在查看http://www.mongodb.org/display/DOCS/Quickstart+Windows 并按照说明操作.谁能告诉我运行MongoDB有什么问题(我使用的是Windows 7)？

Answer 1

安装MongoDB后,您应手动创建数据文件夹.

By default MongoDB will store data in /data/db, 
but it won't automatically create that directory. To create it, do:

$ sudo mkdir -p /data/db/
$ sudo chown `id -u` /data/db

You can also tell MongoDB to use a different data directory,
with the --dbpath option.

有关更多详细信息,请访问MongoDB wiki页面.

Answer 2

我认为你的日志输出清楚地说明了它;

exception in initAndListen: 10296 dbpath (/data/db) does not exist, terminating

您可以简单地创建此目录或更好地将其定义为配置文件中的配置值,然后将其用作mongod -f C:\path\to\your\mongodb.conf.

Answer 3

像这样明确指定数据库路径,看看是否能解决问题.

mongod --dbpath data/db

Answer 4

mongod --dbpath "c://data/db"

运行上面的代码,这将启动服务器.

Answer 5

对于Windows 7

您可以为指定的备用路径\data\db与DBPATH设置为mongod.exe,

如下例所示:

c:\mongodb\bin\mongod.exe --dbpath c:\mongodb\data\db

要么

您可以通过配置文件设置dbpath.
