Answer 1

My mongo (3.2.9) was installed on Ubuntu, and my log file had the following lines:

2016-09-28T11:32:07.821+0100 E STORAGE  [initandlisten] WiredTiger (13) [1475058727:821829][6785:0x7fa9684ecc80], file:WiredTiger.wt, connection: /var/lib/mongodb/WiredTiger.turtle: handle-open: open: Permission denied 
2016-09-28T11:32:07.822+0100 I -        [initandlisten] Assertion: 28595:13: Permission denied 
2016-09-28T11:32:07.822+0100 I STORAGE  [initandlisten] exception in initAndListen: 28595 13: Permission denied, terminating

2016-09-28T11:32:07.822+0100 I CONTROL [initandlisten] dbexit: rc: 100

So the problem was in permissions on /var/lib/mongodb folder.

sudo chown -R mongodb:mongodb /var/lib/mongodb/
sudo chmod -R 755 /var/lib/mongodb

• Restart the server

Fixed it, although I do realise that may be not too secure (it's my own dev box I'm in my case), bit following the change both db and authentication worked.
