Local MongoDB Connection issue using Meteor - meteor

Question

I need to connect a Local MongoDB to Meteor. I did a "LeaderBoard" example in which I tried to connect to Local DB by using the below procedure:
meteor mongo lboard.meteor.com //Deploy project name is lboard.meteor.com
MongoDB shell version: 2.4.8
connecting to: production-db-b3.meteor.io:27017/lboard_meteor_com
then i try to switch DB using the below procedure:
> use lboard_meteor_com
//This time i got the below error
switched to db lboard_meteor_com
Thu Jan 23 15:09:42.125 trying reconnect to production-db-b3.meteor.io:27017
Thu Jan 23 15:09:48.127 reconnect production-db-b3.meteor.io:27017 failed couldn
't connect to server production-db-b3.meteor.io:27017
Also, I get an error in the server console as shown below and I am new to meteor so please have a look at the below and above error and tell me what to do.
Server Console Error Log & What i am did in server is:

Answer 1

If you want to use a local MongoDB instance you should instead set the MONGO_URL environment variable before starting meteor:
export MONGO_URL=mongodb://localhost:27017/dbname
meteor
To connect to the local MongoDB instance, you should also use the mongo shell rather than meteor mongo:
$ mongo dbname
MongoDB shell version: 2.4.9
connecting to: test
