Quick reply will be appreciated.


Give another try yourselves.
Check your log again. expressly your warning and error lines.
If you see the problems, please ask my best friend, he knows what you need to do.

After 3 minutes with google I find a lot of possible solutions for your problem. Please learn, as I did.

Also, perhaps you are better served with the MongoDB forums:

I can heartily recommend the MongoU online courses! M001 and M103 are a great start for those making their first steps with MongoDB.

I think 5 min with google faster then ask a question in a forum.

I think reading the error message would be the fastest solution ^^

exception in initAndListen: 28595 13: Permission denied, terminating

And there’s your problem. Mongo can’t write to it’s storage path. Fix left up for the end user.

Oh for sure…

But I always / often assume that people actually want to learn and understand the products they’re working with, which is why I suggested that OP @Tafsir_Alam check out the online MongoDB trainings.

Working with Graylog is what originally made me check out MongoU. In the mean time I’ve finished at least four of their courses and I’m considering their basic DB admin cert :slight_smile:


are you sure?
I think it can’t listen on port. eg. it is in use.

Yes I’m sure :wink: Because:

WiredTiger is the storage engine - part of the whole init part of initAndListen :wink:


thanks, I missed this part.

Not a problem. Mongo isn’t always exactly clear on what’s going on :smiley:
