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
St         


        

Answer 1

When I ran mongod.exe from Windows Terminal I got a message Unrecognized option: mp. There was an empty mp: in the end of mongod.cfg. Removing that solved the problem for me.
