無法使用Mongoose使用Bitnami MEAN STACK連接到MongoDB

Question

我從AWS（具體來說是Bitnami）購買了MEAN技術堆棧，並且一直熱衷於學習如何部署我的第一個節點應用程序。 但是，實際上要使我的mongo連接正常工作，我碰到了很多牆。 我已閱讀文檔並嘗試了各種解決方法來解決以下問題

根管理員密碼已重置。 這是我使用正確的用戶名和密碼對的證明

> bitnami@ip-172-31-43-127:~/edupal$ sudo mongo admin --username root --password
pwdremoved
MongoDB shell version: 3.0.3
connecting to: /opt/bitnami/mongodb/tmp/mongodb-27017.sock:27017/admin
Server has startup warnings:
2015-06-09T20:11:33.967+0000 I CONTROL  [initandlisten]
2015-06-09T20:11:33.967+0000 I CONTROL  [initandlisten] ** NOTE: This is a 32 bi

> db.myCollection.find()
{ "_id" : ObjectId("5578c11040a096b7fef84aad"), "name" : "Bill", "score" : "9" }

到目前為止，我相信我在證書方面信譽良好。 這是我連接數據庫的方式

// Connect to MongoDB
mongoose.createConnection('mongodb://root:pwdremoved@/opt/bitnami/mongodb/tmp/
mongodb-27017.sock/admin');
mongoose.connection.once('open', function() {

  // Load the models.
  app.models = require('./models/index');

  // Load the routes.
  var routes = require('./routes');
  _.each(routes, function(controller, route) {
    app.use(route, controller(app, route));
  });

  console.log('Listening on port 3000...');
  app.listen(8080);
});

我在這里遵循了教程

而且我不斷收到這個錯誤

我不確定自己在做什么錯，並嘗試了多種連接MongoDB的方法。...我已經呆了兩天了。

Bitnami開發人員在這里。

您發布了可以使用root用戶連接到管理數據庫的信息。

bitnami@ip-172-31-43-127:~/edupal$ sudo mongo admin --username root
--password pwdremoved MongoDB shell version: 3.0.3 connecting to: /opt/bitnami/mongodb/tmp/mongodb-27017.sock:27017/admin

但后來您嘗試連接到“索引”數據庫

mongoose.createConnection('mongodb://root:pwdremoved@/opt/bitnami/mongodb/tmp/mongodb-27017.sock/indexes');

該數據庫是否已創建？ 您可以使用以下命令檢查創建的數據庫：

show dbs

如果要使用管理數據庫，則需要使用以下行：

mongoose.createConnection('mongodb://root:pwdremoved@/opt/bitnami/mongodb/tmp/mongodb-27017.sock/admin');

如果您不想使用root用戶和admin密碼，可以查看本指南以了解如何創建數據庫並向新用戶授予特權。

https://wiki.bitnami.com/Components/mongoDB#How_to_create_a_database_for_a_custom_application.3f

我安裝了Meanstack 3.0.3-0，並按照Wiki中有關如何創建示例TODO列表的教程進行操作，一切正常。 您可以通過以下鏈接檢查它。

我希望這有幫助。
