I assume that you followed the steps, outlined here.
我假设您已按照此处概述的步骤进行操作。
Most probably you have a problem with mongo lock (or at least I had it once while installing on ubuntu). I solved it with the following commands:
很可能你有 mongo lock 的问题（或者至少我在 ubuntu 上安装时遇到过一次）。我用以下命令解决了它：
sudo rm /var/lib/mongodb/mongod.lock
sudo service mongodb restart
P.S.I by myself recently experienced this problem when I was updating my amazon ec2instance. I have not properly shut down mongo before doing this and this resulted in a problem with mongo lock.
PS我自己最近在更新amazon ec2实例时遇到了这个问题。在执行此操作之前，我没有正确关闭 mongo，这导致 mongo 锁出现问题。

Check your log file of mongodb. you will get to know the exact issue.
检查您的 mongodb 日志文件。您将了解确切的问题。
tail -f /var/log/mongodb/mongodb.log
The issue may because of "ERROR: Insufficient free space for journal files"
问题可能是由于“错误：日志文件的可用空间不足”
Increase your volume space that will fix your issue.
增加将解决您的问题的卷空间。

If you got this after a restart... Make sure that you have over 3GB+ of space free else Mongo Won't start.
如果你在重启后得到这个......确保你有超过 3GB 的可用空间，否则 Mongo 将无法启动。

i got the solution by changing the owner of db directory to 'mongodb'
我通过将 db 目录的所有者更改为 'mongodb' 得到了解决方案
`sudo chown -R mongodb:mongodb /data/*`
then type 'mongo'
然后输入'mongo'

I guess the reason why you cannot connect to mongodb is the insufficient space in the drive on your computer.
我猜您无法连接到mongodb的原因是您的计算机驱动器中的空间不足。
