Just installed a clean version of mongodb on Fedora 17 64-bit, but the Mongo service wont run.
I followed these instructions during installation
Running
I just had the same issue and in my case it was caused by installing mongodb following instructions of some websites using non-official repo. If you have the same issue and the answer above are not solving your problem, try uninstalling "mongodb-org" package and reinstalling it following the instructions of the official documentation : https://docs.mongodb.com/manual/tutorial/install-mongodb-on-red-hat/
Remainder to uninstall package in fedora:
sudo dnf remove
