Hi,
I have mongodb installed locally on my osx laptop and on a remote ubuntu
server. Both have mongodb running and I can verify this using the http
diagnostics on port 28017. I'm running the same code on both computers. On
osx everything works fine, but on Ubuntu I can't make a connection to the
database through NodeJS. I keep getting this error:
Error: failed to connect to [localhost:27017]]
message: listen EADDRNOTAVAIL
stack: Error: listen EADDRNOTAVAIL
at errnoException (net.js:769:11)
at Server._listen2 (net.js:892:19)
at listen (net.js:936:10)
at Server.listen (net.js:993:9)
at asyncCallback (dns.js:67:16)
at Object.onanswer [as oncomplete] (dns.js:120:9)
What I don't understand is that I can connect on Ubuntu locally via the
mongo commandline interface. I can also connect to the database on Ubuntu
via the mongo command on my OSX computer. So nothing seems to be wrong with
the installation of MongoDB itself.
Can anyone think of a reason why I can't connect via NodeJS? I have tried
using the mongodb and mongoose packages. Both give me the same error.
Here are the 2 ways I tried:
var mongo = require("mongodb");
var host = "localhost";
var port = mongo.Connection.DEFAULT_PORT;
var db = new mongo.Db('node-mongo-examples', new mongo.Server(host, port,
{}), {});
db.open(function(err, db){
if(err){
log.error('MongoDB connection error:', err);
}else{
log.info("OPEN MONGO CONNECTION");
}
});
And the with mongoose:
var mongoose = require('mongoose');
var db = mongoose.createConnection('localhost', 'node-mongo-examples');
db.on('error', function(err){
log.error('MongoDB connection error:', err);
});
db.once('open', function () {
log.debug("OPEN MONGO CONNECTION");
});
In the logs I see nothing special, and nothing happens either
