Hi @luca1982, You can use the MONGO_URL environment variable to define which MONGO Database should be used by your Meteor App. Refer to=> Environment Variables | Meteor API Docs

I have not used mLab, I think it should be something like

=> refer to https://docs.mlab.com/ , Step 3 in the Quick Start Guide.

Select a datacenter in mlab where your meteor application is hosted. Then mlab will provide you a connection string. Use that connection string as your MONGO_URL when you start your meteor app.

Hi @luca1982, I hope you are running your meteor application using the command “meteor” from the command line. You need to set the MONGO_URL environment variable before running your application. You need to do it in the same Command-line session so that the environment variables is effective. Here is how you can set the MONGO_URL environment variable.

In Windows:

In Mac:

  1. In the terminal, type "export MONGO_URL=“mongodb://<dbuser>:<dbpassword>@ds012345.mlab.com:56789/mydb” and press Enter.
    You should use the connecting string from mlab instead of the example text in bold
  2. You can then type “export” and it will show the currently set Environment variables. You can verify if MONGO_URL is setup properly.
  3. Type “meteor” and press Enter.
    Enjoy your local Meteor App connected to the remote Mongo DB from mlab.
