Hello! I have a local mongo db and I want to transfer it into my ubuntu machine.
So far i have exported the local db issuing the command below:

mongoexport --db local_db --collection myCollection --out myCollection.json

and the json file was created. Now i log in into my machine using putty and try

mongoimport --db cloud_db --collection myCloudCollection --file myCollection.json

and i get the following error:

Failed: error connecting to db server: no reachable servers

Failed: error connecting to db server: no reachable serversmongoimport

i try to restart mongo service sudo service mongod restart but i get the same error.

any help? what Am i doing wrong?

  • Hi,

    Can you connect to your Ubuntu Droplet's MongoDB instance with any other command? Do you see anything in the MongoD logs?

By default, mongoimport will attempt to connect to a MongoDB instance on localhost port 27017. If yours is running on a different port, you will also need to provide --host <hostname>:<port> when using the command.

You can check what port your instance is using by running:

  • netstat -plunt | grep mongo

See here for the full documentation for mongoimport
