Mongodb service won't start

Question

I am not sure why, and the service was working fine just yesterday, all of a sudden I can not get MongoDB to start up.

[root@purr ~]# service mongod start

Answer 1

In my case, it was also showing some lock problems whenever my local system shuts down without stopping the MongoDB server.

But it just worked only by using sudo command:-

$ sudo mongod --port 27017
