Good practice is to check the logs first and find out the actual cause. Here is the log location /var/log/mongodb/ – Muhammad Tariq

It looks like mongo db fails to startup, usually it can be because the lack of permissions on mongodb's internal folders.

Try to check/set:

chown -R mongodb:mongodb /var/lib/mongodb
chown mongodb:mongodb /tmp/mongodb-27017.sock

I've found the thread that talks about here
