Question

I came across a scenario in which the MongoDB password was removed from the DB. Then Lithium showed “Connection was reset.. “, instead of lithium error.

I will explain you step by step:

In Connections.php

Connections::add('default', array(
 'type' => 'MongoDb',
 'host' => 'localhost',
 'database' => 'CWMG'
));

Added user in Mongo:

C:\>Mongo
> use CWMG
> db.addUser('mongo','awesomeness');

Change Connections.php

Connections::add('default', array(
  'type' => 'MongoDb',
  'host' => 'localhost',
  'database' => 'CWMG',
  'login' => 'mongo',
  'password' => 'awesomeness'
));

Now remove the user from Mongo

db.removeUser('mongo');

Change the connection Connections.php – now not using password…

Connections::add('default', array(
 'type' => 'MongoDb',
 'host' => 'localhost',
 'database' => 'CWMG'
));

Now, Connections.php will not work; If you browse the site.. we get an error: “Connection was reset”, some times it will redirect to another website.

The only solution, I found, is to add the user back in MongoDB and also the same in Lithium.

So my question is how do I remove a user from MongoDB, once added?

Answer 1

Finally, I found the solution. It is MongoDB which stores the password association. To remove it I first tried

1. Export Mongo Database
2. Stopped the service
3. Delete Mongo Database
4. Started the service
5. Imported Mongo Database

Checked for the solution.

Same problem

So I tried the final and the only solution:

1. Export Mongo Database
2. Stopped the service
3. Deleted the MongoDB folder
4. Installed Mongo again
5. Started the service
6. Imported Mongo Database

Yes! It is now working OK!
