Just change the default hardcoded mongodb://127.0.0.1 to the location of your MongoDB server.

You can use db.copyDatabase to do this, with a caveat that there is a bug and you can't update the data in Meteor. See <a href="https://github.com/meteor/meteor/issues/61" rel="nofollow">https://github.com/meteor/meteor/issues/61</a>

If you're using the development version of Meteor, you can transfer data from a running MongoDB server by starting your Meteor app, then doing:

<pre><code>mongo --port 3002
</code></pre>

This will connect you to the Meteor app's Mongo server. Now use db.copyDatabase like this:

<pre><code>db.copyDatabase('myappDatabase', 'meteor', 'localhost');
</code></pre>

This will copy the database myappDatabase from a MongoDB server running on the standard port on localhost, to the Meteor app Mongo server. The database name the Meteor app uses is 'meteor'.

Just copy the data to the Meteor MongoDB database - no reason to try to hook Meteor up to the existing database and risk overwriting things.

Use <code>mongoexport</code> to dump your collections individually, then <code>mongoimport</code> to import the files into the database named <code>meteor</code> in the Meteor MongoDB instance. The Meteor MongoDB instance runs on port 3002 with bind_address 127.0.0.1, and the data files are in the Meteor project subdirectory <code>.meteor/local/db</code>.

See <a href="http://www.mongodb.org/display/DOCS/Import+Export+Tools#ImportExportTools-DataImportandExport" rel="nofollow noreferrer">the documentation</a> if you're not familiar with import/export in MongoDB.

All I did was add the IP of my Digital ocean droplet server, instead of localhost, and it worked:

<pre><code>env: {
 ROOT_URL: 'http://yourdomain.com',
 MONGO_URL: 'mongodb://104.236.24.66:27017/meteor',
 PORT: 3002,
 },
</code></pre>

<hr>

EDIT:
use MUP to deploy your meteor projects: <a href="https://github.com/zodern/meteor-up" rel="nofollow noreferrer">https://github.com/zodern/meteor-up</a>

<pre><code>env: {
 ROOT_URL: 'https://www.example.com',
 MONGO_URL: 'mongodb://localhost/meteor',
 },
</code></pre>

Mup uses Docker, and will "link" your 2 containers, thus hosting both the app and mongo on the same VM (server). Your mongoDB shouldn't be accessible from the public IP for security reasons.

You have to keep your app running in one terminal window then open another and type "meteor mongo" and it should work!
