localhost exception does not work for me

[Karrar mohammed]

I'm running mongod on virtual machine (vagrant) and inside the config file ,I've set the authorization to enabled

it is known that the mongod with security enabled(both authentication and authorization) can not authenticate the user since there are no users and here you can create the superuser ("root") on the admin db via connecting to the mongod via the localhost (localhost exception)

but after I connect to the server, when I want to create a root user on admin, an error message pops up saying

Error: couldn't add user: there are no users authenticated

by the way, the steps I followed are exactly the same as that in the course of cluster administration from MongoDB University

how to fix this?

well even with auth enabled, the local user exception exists until the first user is created.... so the error message may just be due to an incorrect command...

one can use a command to create the first user from the vagrant prompt

or one can connect to mongo shell then

use Admin

and here put the create user

depending on where you launch your create user command the syntax differs somewhat but are very similar....

if you post an example it is perhaps just a syntax issue

Hi,

If the localhost exception isn't working for you, I would suspect one of the following scenarios:

• you are not connecting via localhost from the VM's point of view (for example, using the private IP assigned via Vagrant/Virtualbox or connecting via port forwarding from the host machine)
  
  
• you have previously created users on this deployment (which would disable the localhost exception)
  
  
• your MongoDB configuration file has disabled the localhost exception by setting the enableLocalhostAuthBypass parameter to false.

The easiest fix for this would be to restart your MongoDB instance without access control enabled, create the desired admin user, and then restart your MongoDB with access control enabled.

If you want to try to troubleshoot why the localhost exception isn't working, please reply with some more details including your MongoDB server version and the specific mongo command line you are using to connect.

Regards,

Stennie

I'm connecting to mongod like this 

mongo --host 127.0.0.1:28000

28000 is the port defined inside the config file

but how to connect via the localhost from the vm's point of view??

I haven't used vagrant but in virtual box vm you would have to set the nic to bridged to be able to connect from outside of the vm

your screen shot does not show if this mongod is part of replica set

if it is - then run the config of all nodes so they are all set up

log into 1 node i.e. mongo --port 28000

and then run

rs.initiate() 

then

use admin  to change to the admin db

then your create user code
