Question

How to configure MongoDB 3.4 auto start with authentication when OS Ubuntu 16.04 reboot?

I can make this work without authentication but when I add “authorization: enabled” into /etc/mongod.conf, the mongod.service stops working. Please help.

    This problem is solved after changing all file owners to mongodb:mongodb. The files are mongodb.key and files under /var/lib/mongodb. Many thanks to hensen.

Hi @linaizhong

Add the following to /etc/mongodb.conf (I’m expecting you’re using MongoDB 3+)

security:
   authorization: enabled

If you already have the security: section, then make sure the second line is indented.

      Can you activate logging:
      https://docs.mongodb.com/manual/reference/configuration-options/#systemLog.path
      And then post the log here after you try to start MongoDB again.

          Did you fix your problem, since you marked it as an accepted answer?
          If yes, then can you post the solution.

          If no, then it looks like your /var/lib/mongodb is not owned by the user/group that runs MongoDB. If your user/group is mongodb then run this to set the permissions for the path:

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