i am new to mongodb environment working on a project front end, i need to setup the test database created by backend team on my local machine.
I installed the mongod and copied the files given by my team into c:/data/db and started the db with mongod command. I was able to run loopback api on localhost fine for the first time with all the project data.
Suddenly today when I try to use the same local api server (after starting mongo),it was showing the collections but there is not data inside the collections. When i did 'show dbs' command, it is only showing config, admin and local with each 0.00GB size.
Can anyone help me how to fix it and where i was going wrong.
Any help would be greatly appreciated. Thanks in advance.

I deploy a mongodb in a container. and I also successfully connected to mongodb when my backend runs in the local environment. However, when I tried to move the backend to a container as well, it cannot connect mongodb anymore. The connection string remains the same but it failed.
The error shows that mongodb cannot find the user. However, in my local environment, the same connection string works.
After my googling, most guys said I need to change authSource. I have tried to change authSource to admin, it doesn't work even in my local environment. And I am sure the user exists in my admin database. not in api_dev_db. One wired thing is I can connect to mongodb in my local environment but not work in docker.
Could you kindly help me out?
Here I post some pictures.
These are the env variables I defined in my local environment and they work
This is how I deploy backend service
This is my backend dockerfile
This is the error when I deploy backend in container
This is how I initial mongodb
The problem is I need to remove '' in env variable, which is MONGO_URL=mongodb://api_user:api1234#mongodb:27017/api_dev_db?authSource=api_dev_db
good day to you all.
I am currently having a hard time restoring the MongoDB database.
Here is what happened.
Thanks for looking into this matter
Basically, my server and MongoDB 3.2 server running on DigitalOcean.
I made some changes on mongod.conf file to allow remote access from my local machine. Since then, it no longer worked. I got Mongodb connection failed issue so reinstalled new Mongodb version 4.4 and it doesn't want to load existing data which is located in var/lib/MongoDB. So I downloaded the whole data files as posted above on my local machine.
Now, at least I want to open the current database on my local machine but I couldn't find any proper way to achieve this. Thanks again for looking into this issue.
When I meteor deploy my app, it seems to create an entirely new mongodb instance. I'd like to be able to deploy with the current mongodb have locally.
Same goes the other way -- I'd like to be able to download the mongodb back to my localhost after it has been deployed.
For clarification, I'd really like to know the follow:
1) how to deploy with a fresh mongodb
2) how to deploy to an existing deployed app without overwriting the old mongodb
3) how to download/sync mongodb locally with the existing deployed app
4) how to make local backups of mongodb
You can perform a mongo dump using meteor mongo to export your local database and deploy your app using Meteor Up which should also allow you to automate the database import and deployment process.
"Meteor Up (mup for short) is a command line tool that allows you to deploy any meteor app into your own server."
You can stop the mongodb service and start a mongod instance in a separate terminal, by just typing mongod. This will let you monitor what's happening on the mongodb instance that you just started.
Open another terminal and do export MONGO_URL=mongodb://localhost:27017/nameOfDBgoesHere
This will create a new DB named "nameOfDBgoesHere" and it won't overwrite what you currently have, unless you name it with the same name.
After that just start meteor by typing meteor in your program's folder. In the mongod terminal that you opened you should see some connections opening.
By default mongodb creates it's DB files in /data/db. If you have another meteor app and follow the same steps in another terminal, while keeping the name of the DB you specified in the MONGO_URL you will just connect to it from that app - without overwriting anything.
As for the syncing with a deployed app and the local backups of mongo - it seems like something that the mongodb website covers, but maybe someone can chime in here. Not sure if there is a meteor specific, easy way of doing this.
situation
Hello, I run arch Linux for which there is no meteor package and have an Ubuntu server run within virtualbox for web development. There is a shared folder I mount through database. hich means I can code in to the active environment.
However, like many others, I have a problem with mongodb starting up, specifically the exit code 100.
tracing the problem:
I created the /data/DB directory
gave access rights to my user
ran mongod on its own with no problems
Still I have the issue though.
Question
Where is the configuration file for mongodb which is installed with meteor so I can move it and do I need to create rights for a 'mongodb' user?
Question
What would be the ideal virtual machine for running a meteor development environment in the above set up? Having to create the data directory in the first place tells me Ubuntu server isn't ideal. some extra documentation available to answer this second question appearing on the meteor website would be beautiful
MongoDB does not work correctly on virtualbox shared folders. By default, meteor creates a mongo database in your project's directory, however you can override this behavior with the MONGO_URL environment variable. If you set this variable, meteor will not try to start mongo and will instead connect directly to the mongo endpoint you specify. This allows you to setup mongo however you like (eg using the Ubuntu mongodb package), with data somewhere not in the shared folder.
This question is specific to MongoVUE, but really I am looking to be able to log in to Mongo on EC2 in any way besides through the SSH tunnel. I can do that and get a server and client up and running, create documents, find things etc. I am new to mongo and ec2 so I will admit there are a lot of variables.
Here is what I've done so far:
I have created a unique database and then added a user to that with the db.addUser('name','password') command.
I am using the public dns that AWS provided which looks like, xxxx.us-west-1.compute.amazonaws.com
I have tried to log in with the plain text password as well as the one mongo displays (hashed).
My ultimate goal is to be able to connect through C#, but MongoVue gives me an easier platform to fiddle around with (I hope).
Any help would be great! Thank you.
I was trying to do the same thing and it actually ended up being pretty easy after following the instructions on Mongovue's Blog
http://www.mongovue.com/2011/08/04/mongovue-connection-to-remote-server-over-ssh/
This allows you to not have to open up the MongoDB port externally also.
Make sure you also convert your EC2 .pem key to a Putty Key via PuttyGen first.
Okay, I solved it for those of you that will find this question and be in the same boat. For some reason I could not change my security group on ec2 to the one I had given access to port 27017. So I added that port exception to the security group that was currently assigned to my instance.
I then had to log in through SSH to get the Mongo server up and running (simply run the mongod command in the bin directory) and then it logged right in. I used the username and password that I had set up earlier through the mongo command line.
I hope this helps someone.
