[Error: failed to connect to [localhost:27017]] from NodeJS to mongodb

Question

I am having problem connecting to MongoDB from NodeJS using following sample code. I tried running "mongod" with or without sudo but nodejs code still fail to connect. I am able to successfully connect to database using "mongo". Running on : MAC OS 10.6.8 ``` var mongoClient = require('mongodb').MongoClient; mongoClient.connect("mongodb://localhost:27017/test", function(error, db) { if(!error){ console.log("We are connected"); } else console.dir(error); }); ``` get following error running above code : [Error: failed to connect to [localhost:27017]] Also tried mongoose but similar error: ``` var mongoose = require('mongoose'); mongoose.connect('mongodb://localhost/test'); var db = mongoose.connection; db.on('error', console.error.bind(console, 'connection error:')); db.once('open', function callback () { console.log("DB connected"); // yay! }); ``` Output: connection error: [Error: failed to connect to [localhost:27017]] Here is the log of mongod ``` mongod --help for help and startup…

Accepted Answer

Never mind, I was able to resolve the issue by using 127.0.0.1 instead of localhost, not sure why I have to use ip address. My tomcat, apache, redis, and even node server all works using localhost but not the mongodb. Is there is config I need change to make it work using local host?
