I want to create replica set and for that I had to configure mongodb for internal authentication. I did as per the mongodb documentation. I created key file and gave "600" access to file. I am using root user to start the server but getting following error.
2019-03-17T10:40:28.195+0300 I ACCESS [main] error opening file: /etc/key: Permission denied
I don't understand why for opening file user root is getting permission denied error though I've give read and write access to this file for user root.
