I am trying to restore a MongoDB on an EC2 instance. I am currently running Mongo 4.0. I am restoring a .tgz, which I then unzip, and it contains a directory with all of my files. I previously used this command:
sudo mongorestore --db newDB mongoDump-2018-07-25-0200/viboDB/
Now that I am trying to update our database, I am getting the following error.
building a list of collections to restore from mongoDump-2018-07-25/0200 dir
Failed: viboBI2.Songs: error reading database: command listCollections requires authentication
I have logged into the mongo shell, and used db.auth() to authenticate as an admin. I have tried restarting mongo as well. Any help would be appreciated!
For restoring the Database you need to provide authentication.
mongorestore -u USERNAME -p PASSWORD --authenticationDatabase admin -d dbNAME PATH/TO/DIRECTORY
you can also provide host and port by adding -h and --port

I am trying to export my local mongodb data to an atlas cluster and i created a dump and now i am using the command,
mongorestore --host Cluster0-shard-0/cluster0-shard-00-00-qwo7v.mongodb.net:27017,cluster0-shard-00-01-qwo7v.mongodb.net:27017,cluster0-shard-00-02-qwo7v.mongodb.net:27017 --ssl --username username --password <PASSWORD> --authenticationDatabase admin
to try to restore it but is giving me the system cannot find the file specified.
But if i type mongorestore then it works but it doesn't restore to the atlas cloud server whatever.
What am i doing wrong?
Edit: The path i have used is C:\Program Files\MongoDB\Server\4.2\bin\dump\gfg and dump\gfg but it is still not working.
Usage of MongoRestore.exe can be found here.
Standalone MongoDB
When you use mongorestore, you need to provide the location of the file/dump you need to restore
mongorestore --host=mongodb1.example.net --port=27017 --username=user --authenticationDatabase=admin /opt/backup/mongodump-2011-10-24
last portion of the command is missing that defines the location of the data that needs to be restored.
ReplicaSet
To Restore MongoDB on a Replica, You have to stop the mongod and replace the files for mongodb. Please read here for restoring database on replica set.
For restore from standalone to replica,
mongorestore --host myReplSet/mongo0.example.com:27020,mongo1.example.com:27012 --db <dbname> <folder_location>
If this still does not work, check path and ensure its properly escaped (spaces in name) or quoted.
Your code with quotes and path:
mongorestore --host Cluster0-shard-0/cluster0-shard-00-00-qwo7v.mongodb.net:27017,cluster0-shard-00-01-qwo7v.mongodb.net:27017,cluster0-shard-00-02-qwo7v.mongodb.net:27017 --ssl --username username --password <PASSWORD> --authenticationDatabase admin "C:\Program Files\MongoDB\Server\4.2\bin\dump\gfg"
Using mongorestore, I am trying to restore a MongoDB database to a new server (both version are 3.4). The new server has -auth enabled, so you are required to login. The database does not exist so I want mongorestore to create it using the --db option. This works when authorization is not enabled but if I enable authorization the restore fails with the following error:
Failed: error connecting to db server: server returned error on SASL authentication step: Authentication failed.
I am using an admin account with the root role when I attempt the restore.
Backing up prod and restoring to dev is a fairly regular activity for us, but we can't just drop the existing database and recreate it because of the error above, not unless we disable authorization which doesn't make much sense. Is there a better way to do this/avoid the SASL errors/not have to disable auth?
I was getting the same error and while I couldn't figure out what was wrong restoring with my admin user (my hunch is a ! in the password which escaping did not help) I was able to restore by creating a new user specifically for the role.
In mongo shell:
>use admin;
>db.createUser({
user: 'restoreuser',
pwd: 'restorepwd',
roles: ['restore']
});
In terminal:
$mongorestore --host databasehost:12345 --username restoreuser --password restorepwd --authenticationDatabase admin --db targetdb ./path/to/dump/
Thanks to Adamo Tonete over at Percona, he helped us solve this problem. If you want to restore a database using your admin user with the root role, you need to specify the authentication database and user in the mongorestore command.
mongorestore --host hostname:27017 -u adminuser -p pass --authenticationDatabase admin -d TargetDatabase /Data/TargetDatabaseRestore
That tells mongo to use the admin database to authenticate the user you are passing in. If that user has the correct rights assigned, it will be able to create the new database.
First Access your db to 4366 port then run this command
mongorestore --port 4366 -u admin -p password --authenticationDatabase admin -d dealmoney /home/yash/Desktop/prodDump/teatingToProductionLastDump/dealmoney .
I have a MongoDB database that resides on a remote server machine whose IP address is 192.168.1.20 on a local network. For development and testing purposes, and since I am not allowed to modify or delete the database on the server for security purposes, I want to copy the database on my local machine for my personal use.
Can anyone please tell me, how do I achieve this?
I do this by creating a dump of the remote db to my local machine, which I then restore:
Make sure you have a mongo instance up and running (eg. run mongod.exe from your bin folder in a terminal window. On my windows computer that's C:\mongodb\bin)
Make a dump from remote db: Open a new terminal window, move to the bin folder again, run:
mongodump -h example.host.com --port 21018 -d dbname --username username --password yourpass
(Change the parameters to suit your own situation.)
Restore the dumped database: Once the dump has been made, run the following command so that you have a local db:
mongorestore -d theNameYouWantForYourLocalDB dump\nameOfRemoteDB
(replace nameOfRemoteDB with the name of the remote db, the same as in previous command, and replace theNameYouWantForYourLocalDB with the name that you want your new local db to have)
There is copy database command which I guess should be good fit for your need.
db.copyDatabase("DATABASENAME", "DATABASENAME", "localhost:27018");
Alternatively, you can just stop MongoDb, copy the database files to another server and run an instance of MongoDb there.
EDIT 2020-04-25
Quote from MongoDB documentation
MongoDB 4.0 deprecates the copydb and the clone commands and their mongo shell helpers db.copyDatabase() and db.cloneDatabase().
As alternatives, users can use mongodump and mongorestore (with the mongorestore options --nsFrom and --nsTo) or write a script using the drivers.

This should be a comment to the answer of #malla, but I don't have enough reputation to comment so I'm posting it here for other's reference.
In step 2, When you are trying to dump file from a remote server, remember to add out option so that you can restore locally later: (in my first try, I didn't add it and it failed, saying dump\db_name was not found).I'm not sure whether my way efficient or not. But it worked for me.
Step 2:
mongodump -h example.host.com --port 21018 -d dbname --username username --password yourpass --out <path_you_want_to_dump>
Step 3:
mongorestore -d theNameYouWantForYourLocalDB \<path_you_want_to_dump> + nameOfRemoteDB
The mongoexport command:
http://docs.mongodb.org/manual/core/import-export/
Or, mongodump command:
http://docs.mongodb.org/manual/reference/program/mongodump/
mongodb has commandline tools for importing and exporting. Take a look at mongodump --collection collection --db test and mongorestore --collection people --db accounts dump/accounts/
http://docs.mongodb.org/v2.2/reference/mongodump/
http://docs.mongodb.org/v2.2/reference/mongorestore/
this even works over the network
You can use the mongoexport command to copy the database to your local machine.
So I have been playing around with meteor and mongodb and have a working version set up on my localhost. Unfortunately, when I do meteor deploy xxx.meteor.com it doesn't deploy my database as well.
How do I do this?
Meter deploy only deploys a fresh database. To copy over your data you have to use mongorestore with your local mongodb dump, which you can make with mongodump (docs)
So first dump your database somewhere
mongodump --host localhost:3002
Get your mongodb`s credentials by running (in your project dir):
meteor mongo myapp.meteor.com --url
This will give you your database details in the form:
mongodb://username:password#host:port/databasename
Then you can plug these into mongorestore (docs) and restore your local database over
mongorestore -u username -p password -h host:port -d databasename ~/desktop/location_of_your_mongodb_dump
Perhaps I have a complete misunderstanding of how mongodump is supposed to work, but I can't seem to get it to do anything besides returning a JavaScript execution failed: SyntaxError: Unexpected identifier error.
Here's what I'm doing:
Mongod is running
I want to backup a database called "mydb"
I'm inside the mongo shell
I tried the command mongodump --db mydb and get the above error
I've tried both mongodump and mongoexport, both have the same issue
What am I doing wrong here?
Try the following it will work
i.Open the terminal
ii. Enter mongodump --collection collectionname --db dbname (Don't go inside mongo shell);
iii.If default port is different(other than 27017) then go for the following command
mongodump --host mongodb1.example.net --port 37017 --username user --password pass --out /opt/backup/mongodump-2011-10-24
mongodump,mongorestore is not commands of mongodb shell. It is separate mongodb utlity. You can find it under mongodb bin folder.
Usually you will need to add all mongodb utilities to the system Path variable and after this easy backup/restore databases from any place in the command line or in the terminal.
Your command looks mongodump --db mydb good if your databases in on default port(27017).
I faced the problem in taking mongo dump and I also wanted to store the dump to S3. Finally I ended up with a bash script to take mongo dump and store it to S3. I used mongodump to take backup.
mongodump -h $MONGO_HOST:$MONGO_PORT -d $MONGO_DATABASE
Where $MONGO_HOST,$MONGO_PORT and $MONGO_DATABASE are bash variables for host, port and database-name respectively.
You can also use --username user --password pass option for mongodump command if you have username and password setup on the database.
Here is the script to take mongodb dump and store it to S3 with a cron.
