Ruby on rails 3 mongodb服务器启动时出错

对mongodb来说是全新的。我试图在我的服务器上安装Motorpore CMS，这很酷，但我一直使用SQL/MySQL，所以mongo对我来说是全新的

我安装了所有需要的mongodb模块，但是当我运行：

sudo服务mongod start

时，我得到一个错误代码。当我在日志中查找错误时，以下是输出：

另外，我运行：

sudo服务mongod status

，输出是

mongod已停止

，因此我知道它没有运行

从堆栈来看，这个错误似乎与空间不足有关，但我的服务器有15gb的空闲空间，我正在运行sudo，所以我知道这不是权限错误…我如何分配更多空间…或者更好的是，我应该分配更多空间给什么

非常感谢您的帮助。

将smallfiles=true添加到“/etc/mongodb.conf”

现在尝试启动服务，我想这应该可以解决问题

设置为true可修改MongoDB以使用较小的默认数据文件大小。具体来说，smallfiles减少了数据文件的初始大小，并将其限制为512 MB。smallfiles设置还可以将每个日志文件的大小从1GB减少到128MB。
