I created a new Database called meanapp.and I add a user meanUser for readWrite role.
When I connect to the mongo DB via mongoose it connects but I got Error as
{ MongoError: not authorized on meanapp to execute command { listIndexes:"jobs", cursor:{}}
So , I tried to grant dbAdmin role to meanUser by executing
db.grantRolesToUser('meanUser',[{role:"dbAdmin", db: "meanapp" }] )
And tried restarting mongo deamon.
And db.getUser('meanUser') shows the dbAdmin role for that user.
Still same error.
Could any one faced this issue or I am missing something?
I refered mongo docs also I could get an idea of this issue.
Thanks for your effort.

I'm trying to connect postgres database from sequelize (node.js).But sequelize throws error like ERROR: database "public" does not exist.
The database url is given below:
postgres://postgres:root#localhost:5432/public
The show db result is given below:
I have modified the database url as follows:
postgres://postgres:root#localhost:5432/postgres, where postgres is valid database.Please find the attached image below:
database and schema in postgresql are not the same object .. you should provide the database name not the schema name
you could get the list of the database using
psql -U pgadmin -l
The postgres database is a default database meant for use by users, utilities and third party applications.
If you don't specify a database while connecting to postgres (using, day, psql), it will connect to postgres DB.
It is possible that you connected to postgres without specifying the DB and created the tables. Hence they were created in postgres DB.

i am trying to connect to my mongo database with following connection string
var Mongo_url = 'mongodb://MyUSer:tech#localhost:27017/chatme?authSource=admin';
I am getting error as
assertionError: null == { [MongoError: Authentication failed.]
name: 'MongoError',
message: 'Authentication failed.',
ok: 0,
code: 18,
Could anyone please clear this "authSource=admin" thing to me.
This is the name of the database that has the collection with the user credentials.
https://docs.mongodb.com/manual/reference/connection-string/#connections-connection-options
This is where the usernames and passwords are set up.
I spent a few hours today trying to solve this problem and unfortunately, this SO post didn't appear in my searches. That was too bad because it's the post with the best answer to the problem.
I hope to help the next person by adding the error message I got.
I'm setting up the connection inside a Docker container that is spun up via a docker-compose yaml file. The user name and password are passed into docker-compose from a .env file.
Connection URI that works
mongodb://aUser:aPassword#mevn-app-mongo:27017/myDb?authSource=admin
Error:
SASL SCRAM-SHA-1 authentication failed for aUser on myDb from client 172.25.0.3:37352 ; UserNotFound: Could not find user aUser#myDb
So we are having an interesting problem. We wanted to add authentication at the MongoDB Layer for more security. But we not getting a favorable outcome.
Pre-Setup
Use mongo shell (against admin table) as root
Switch to desired database (applicationdb)
Execute db.createUser()
Validate user was created successfully
{
"_id" : "applicationdb.appuser",
"user" : "appuser",
"db" : "applicationdb",
"roles" : [
{
"role" : "readWrite",
"db" : "applicationdb"
}
]
}
Scenario 1:
Change mongodb.conf, auth=true
Restart the Mongod service
Connect mongoose using:
mongoose.connect('mongodb://appuser:password#xx.xxx.xxx.xxx:27017/applicationdb');
No errors received for connect, so try to perform a GET through Mongoose causes the operation to timeout without any error (at least that I could find)
Scenario 2:
Change mongodb.conf, auth=false
Restart the Mongod service
Connect mongoose using:
mongoose.connect('mongodb://xx.xxx.xxx.xxx:27017/applicationdb');
No errors received for connect, so try to perform a GET through Mongoose and it returns documents successfully
Why do we get this timeout and never a completed request when using authentication in MongoDB?
Any help would be great, we're at a loss on this one!
You need to restart the mongo service with the --auth option see here
If it doesn't works do this:
Try setting server options in mongoose with keepAlive set. See here and here.
I wrote a node web app and created a mongoDb database on my local system. I was using the following code to connect to local mongodb from node js
var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/db_name'); //local
And everything was working fine on my local machine. So I went on and created an mlab account and created a database. But when I tried to run the code by changing the connection string, connections are still established I believe. But the find and save requests are not invoking the callbacks, even no errors shows up. All requests are getting timed out.
var mongoose = require('mongoose');
mongoose.connect("mongodb://user:pass#ds036789.mlab.com:36789/db_name"); //mlab
Another thing I noticed is that I cannot ping ds036789.mlab.com. But TCP connections are succeeding when I tried the nc command
nc -w 3 -v ds036789.mlab.com 36789
I even tried deploying to azure. Which doesn't work either. Any help is much appreciated. Thanks.
EDIT:
Not being able to ping was due to the fact that I used azure hosting. It is expected. And I also found out that I get this error while trying to connect :
connection error: { [MongoError: auth failed] name: 'MongoError', ok: 0, errmsg: 'auth failed', code: 18 }
Credentials are correct though.
From the error mesasge it seems like you are using invalid auth details
This is most likely happen when you do not create username and password for individual database i.e, db_name in you case.
Check mLabs account and create username and password for db_name database and update your connection string.
According to the error information, as #Astro said, it seems to be caused by using invalid auth user/password which be created for database.
Did you create a new user for connecting the database, not account user for mlab? Such as the figures below shown.
Fig 1. A database user is required for connecting
Fig 2. Users list for the database
Hope it helps.
I figured out the issue, it wasn't an issue with the credentials. It was an issue with the mongoose version. The mongoose version I used didn't support the authentication. I had to remove the package and reinstall the latest version. with
node install mongoose#latest
Hope it helps someone. And thanks for the answers :)
I'm using node.js with mongoose which cannot connect to the DB failing with authentication issue.
Using the connection env variable uri:
:mongodb://root:***#[appname]-[user]-db-0.azva.dotcloud.net:4518
And the result is:
{ [MongoError: auth fails] name: 'MongoError', errmsg: 'auth fails', ok: 0 }
Tried to build up own conn URI based on the environment variables like DOTCLOUD_DB_MONGODB_HOST etc, the URI is correct, passing to the env variable but the problem is still this based on the DB logs:
db.0 Sat Dec 29 00:31:08 [conn66] auth: couldn't find user root, admin.system.users
Could anyone help me how to resolve this missing user root?
Thank you in advance!!!
update: I logged in to mongodb console on the mongodb node via "use admin" and cannot authenticate with that username and password either. Nor create a new user and password. :(
Resolved.
The dotcloud system has provisioned the db instance badly somehow.
Creating a new app, everything is working fine.
