Question

我从AWS购买了MEAN技术堆栈（Bitnami是具体的），并且一直在热切地学习如何部署我的第一个节点应用程序。但是，我已经打了这么多墙，实际上让我的mongo连接工作。我已阅读文档并尝试了各种方法来解决下面的问题

根管理员密码已重置。以下是我使用正确的用户名和密码

的证明

> 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:

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

到目前为止，我相信我在资历方面表现出色。这是我连接到我的数据库的方式

// 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);
});

我按照教程here

进行了操作

我一直收到此错误

我不确定我做错了什么，尝试了很多连接到MongoDB的变种....我已经被困了两天了。

Bitnami开发者在这里。

您发布了可以使用root用户

连接到管理数据库的信息

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

但后来你试图连接到“索引”数据库

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

是否创建了该数据库？您可以使用以下命令检查创建的数据库：

show dbs

如果您想使用admin数据库，则需要使用以下行：

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

如果您不想使用root用户和管理员密码，可以查看本指南以了解如何创建数据库并向新用户授予权限。

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

我安装了Meanstack 3.0.3-0，我按照wiki中关于如何创建示例TODO列表的教程，一切正常。您可以通过以下链接查看。

https://wiki.bitnami.com/index.php?title=Infrastructure_Stacks/BitNami_MEAN_Stack_(MongoDB%2C_Express%2C_Angular%2C_Node.js)#How_to_create_a_sample_TODO_list_project_with_MEAN.3f

我希望这会有所帮助。

使用Mongoose无法使用Bitnami MEAN STACK连接到MongoDB
