In my case the error was due to missing /data/db folder which the mongodb uses to store your data. Please type this command $sudo mongodin your terminal. If the error message is something like :
在我的情况下，错误是由于缺少 mongodb 用于存储数据的 /data/db 文件夹。请$sudo mongod在您的终端中输入此命令。如果错误消息类似于：
missing data/db folder error
missing data/db folder error
Simply create the folder and you are good to go.
只需创建文件夹即可。

Probably you don't have space in your hard drive.
Check it by typing in the promt df -h
可能您的硬盘驱动器中没有空间。通过在prom中输入来检查它 df -h
Please note that mongo might fail even with 3gb available in the corresponding partition. For details, you might want to check the log: cat /var/log/mongodb/mongod.log
请注意，即使相应分区中有 3gb 可用，mongo 也可能会失败。有关详细信息，您可能需要查看日志：cat /var/log/mongodb/mongod.log

I think except for disk space issuse, you should check the log in /var/log/mongodbto know the details for why mongodb start failed.
我认为除了磁盘空间问题之外，您应该检查登录/var/log/mongodb以了解mongodb启动失败的详细信息。
cat /var/log/mongodb/mongod.log

So, here I need to rm all the files in the /tmp. That works fine for me.
