nodejs mongodbを使ってmongodbに接続するshard分布サービスです.

var MongoClient = require('mongodb').MongoClient
  , format = require('util').format;

var url = format("mongodb://%s,%s/%s"
  , "192.168.0.60:27017"
  , "192.168.0.64:27017"
  , "test");

//var url = "mongodb://192.168.0.60/test";
console.log(url);
MongoClient.connect(url, function(err, db) {
  if(!err) {
    var collection = db.collection('test');
    console.log(collection);
    collection.find({}).toArray(function(errfind, items) {
      if(!errfind) {
        console.log(items);
      } else {
        console.log(errfind);
      } 
      db.close();
    });

    console.log("We are connected");
  }
//  db.close();
});
