I have the following command
mongo clean_collection.js --host localhost --username root --password example
Clean_collection.js file contains:
conn = new Mongo();
db = conn.getDB("MyDb");
var myColl = db.getCollection('MyCollection');
myColl.drop();
But MongoDb returns:

i am trying to pull records form mongo data base with json format to do that i am running below js :
conatin of get_DRMPhysicalresources_Data.js
cursor = db.physicalresources.find().limit(10)
while ( cursor.hasNext() ){
print( JSON.stringify(cursor.next()) );
}
the command i run to get the records :
mongo host_name:port/data_base_name -u user -p 'password' --eval "load(\"get_DRMPhysicalresources_Data.js\")" > DRMPhysicalresources.json
and i am able to get the result as josn formate inside DRMPhysicalresources.json , now i want to switch to other data base using use command i try add use db as below :
conatin of get_DRMPhysicalresources_Data.js
use db2_test
cursor = db.physicalresources.find().limit(10)
while ( cursor.hasNext() ){
print( JSON.stringify(cursor.next()) );
}
the command i run to get the records :
mongo host_name:port/data_base_name -u user -p 'password' --eval "load(\"get_DRMPhysicalresources_Data.js\")" > DRMPhysicalresources.json
but i am getting below errors :

is there are any way to add use db2_test without break it ?
You can try this:
db = new Mongo().getDB("myOtherDatabase");
or
db = db.getSiblingDB('myOtherDatabase')
( this is the exact js equivalent to the 'use database' helper)

I want to use authentication in my mongodb. So I created a user. Which this user I can connect on command line and insert data without any problem.
But when I want to use this user in grails, I get this error:
{ "serverUsed" : "127.0.0.1:27017" , "ok" : 0.0 , "errmsg" : "auth failed" , "code" : 18 , "codeName" : "AuthenticationFailed"}
When I connect from commandline, everything works:
mongo --port 27017 -u "mongouser" -p "pwd" mydb
My code in Grails:
MongoCredential credential = MongoCredential.createMongoCRCredential("mongouser", "mydb", "pwd".toCharArray())
def mongoClient = new MongoClient( new ServerAddress(host, port), [credential ] )
gMongoCon = new GMongo(mongoClient)
What is wrong here?
Add your mongo credentials in Config.groovy or external config as follows,
grails
{
mongo
{
host = "YOUR_HOST_NAME_OR_IP_ADDRESS" // e.g localhost
port = 27017
username = "mongouser" //Username
password = "pwd" //password
databaseName = "mydb" //Database name
}
}
Note: change the bind_ip from /etc/mongod.conf if the application and
mongo are on different server.
This solution works:
MongoCredential.createCredential(username, datatable, password)
I have a MongoDB server where I have enabled authentication and created users with DB-specific permissions. The user for this app is defined as shown below i.e. geoAdmin has read, readWrite and dbOwner permissions for the relevant database:
MongoDB shell version: 3.0.0
connecting to: 192.168.2.89/test
> use geo_db
switched to db geo_db
> db.getUser("geoAdmin")
{
"_id" : "geo_db.geoAdmin",
"user" : "geoAdmin",
"db" : "geo_db",
"roles" : [
{
"role" : "read",
"db" : "geo_db"
},
{
"role" : "dbOwner",
"db" : "geo_db"
},
{
"role" : "readWrite",
"db" : "geo_db"
}
]
}
The following query works OK i.e. connecting to the remote server from my local mongo client:
mint:~ $ mongo 192.168.2.89:27017 -u geoAdmin -p secret --authenticationDatabase geo_db
MongoDB shell version: 3.0.0
connecting to: 192.168.2.89/test
> use geo_db
switched to db geo_db
> db.LAD_DEC_2013_GB_BFE.findOne({},{'properties.LAD13NM':1})
{
"_id" : ObjectId("54ffe2824f0787ec1293017f"),
"properties" : {
"LAD13NM" : "Hartlepool"
}
}
I then connect to the same remote host from a ReactiveMongo Play app on the same local client, with this URL in the app config file:
# ReactiveMongo
mongodb.uri = "mongodb://geoAdmin:secret#192.168.2.89:27017/geo_db"
But when my app tries to read from the same collection, I get a MongoDB "code = 13" error:
[DetailedDatabaseException: DatabaseException['not authorized for query on geo_db.LAD_DEC_2013_GB_BFE' (code = 13)]]
The app works fine if I connect to a local MongoDB which does not have authentication enabled.
Any ideas what might be going wrong here?
ReactiveMongo 0.11.7.play23 is supporting mongo 3.0 auth-protocols, but is still using the old as default.
With ReactiveMongo 0.11.7.play23 -plugin, you can make it authenticate with mongo 3.0, by adding "?authMode=scram-sha1" to the end of your mongodb.uri.
E.g.:
mongodb.uri = "mongodb://geoAdmin:secret#192.168.2.89:27017/geo_db?authMode=scram-sha1"
mongo 2.6 uses MONGODB-CR auth protocol and 3.0 uses MONGODB-SHA-1 by default
reactivemongo use MONGODB-CR auth protocol(not sure)
downgrade mongodb 3.0 auth mechanisms to MONGODB-CR
login mongo noauth
remove all user
update the version document for the authSchema.
ex.
db.getSiblingDB("admin").system.users.remove( {} )
db.getSiblingDB("admin").system.version.update(
{ _id: "authSchema" },
{ $set: { currentVersion: 3 } }
);
add authSource parameter to mongodb url
ex.
mongodb.uri = "mongodb://geoAdmin:secret#192.168.2.89:27017/geo_db?authSource=geo_db"
I am trying to get MongoDB running on my localhost (Windows) with authentication.
To do so, I first have to add a user, right?
I did so by starting the daemon using this command:
C:\[…]\mongod.exe -f C:\[…]\mongo.config
mongo.config contains the following:
# Basic database configuration
dbpath = C:\[…]\db\
bind_ip = 127.0.0.1
port = 20571
# Security
noauth = true
# Administration & Monitoring
nohttpinterface = true
After that I connected via this command:
C:\[…]\mongo.exe --port 20571 127.0.0.1
There I added a user:
> use admin
switched to db admin
> db.addUser('test', 'test')
{ "n" : 0, "connectionId" : 1, "err" : null, "ok" : 1 }
{
"user" : "test",
"readOnly" : false,
"pwd" : "a6de521abefc2fed4f5876855a3484f5",
"_id" : ObjectId("50db155e157524b3d2195278")
}
To check if everything worked I did the following:
> db.system.users.find()
{ "_id" : ObjectId("50db155e157524b3d2195278"), "user" : "test", "readOnly" : false, "pwd" : "a6de521abefc2fed4f5876855a3484f5" }
Which seemed OK to me.
After that I changed "noauth = true" to "auth = true" in the mongo.config file and restarted the daemon.
Now I expected to be able to connect with user and password:
C:\[…]\mongo.exe --port 20571 -u test -p test 127.0.0.1
Which denied access to me with this message:
MongoDB shell version: 2.0.4
connecting to: 127.0.0.1:20571/127.0.0.1
Wed Dec 26 16:24:36 uncaught exception: error { "$err" : "bad or malformed command request?", "code" : 13530 }
exception: login failed
So here's my question: Why does the login fail?
I can still connect without providing user and password, but can't access any data because "unauthorized db:admin lock type:-1 client:127.0.0.1". Which is actually what I expected.
As Andrei Sfat told me in the comments on the question I made 2 major errors.
First, I thought I could pass the IP to the Client as a simple argument. But you have to use --host for that.
Instead, the parameter I thought was the IP address actually should be the db name.
So the correct command to connect to a Server is as follows:
C:\[…]\mongo.exe --port 20571 -u test -p test --host 127.0.0.1 admin
Second, users are per database. As I only added the user "test" to the db "admin", it only works there.
Obviously the auth = true configuration wasn't load successfully. Did you forget the -f paramter when you restart the mongod.exe?
C:\[…]\mongod.exe -f C:\[…]\mongo.config
I have restarted 2 shards on non standard ports, by chaning their .conf files. Now when I connect via mongo and issue a listshards I get:
mongos> db.runCommand( { listshards : 1 } );
Tue Oct 23 17:36:21 uncaught exception: error {
"$err" : "error creating initial database config information :: caused by :: socket exception [CONNECT_ERROR] for vserver-dev-2:37017",
"code" : 11002
}
(37017 is the old port).
How can I update the shard ports on the router (mongos) ?
Manual updating the ports on the mongo config server:
mongo
use config
configsvr> db.shards.update({_id: "shard0000"} , {$set: {"host" : "vserver-dev-2:37018"}})
configsvr> db.shards.find()
{ "_id" : "shard0000", "host" : "vserver-dev-2:37018" }
