MEAN.js Could not connect to MongoDB

Question

in creating my app with MEAN.js can not do mongodb connect on port 27017 in any way. I installed mongodb manually in directory

~$ ls -la /etc/init.d/mongod 

output

lrwxrwxrwx 1 root root 56 Nov 4 20:45 /etc/init.d/mongod -> /home/myuser/projects/packages/linux-mongodb/bin/mongod 
I try to run the file or `` server.js` grunt` the NASC repository command and got the following error:

Running node server.js i receive this output:

Application loaded using the "development" environment configuration 
Failed to load c ++ bson extension, using pure JS version 
Insecurely using http protocol 
MEAN.JS application started on port 27017 
Could not connect to MongoDB! 
Error: connection closed 

Repository URL: https://github.com/meanjs/mean

Some hint of what might be? I look forward personal contact. Thanks in advance!

I am no longer using MEAN.js, but I continue my studies with MongoDB and node.js

The problem was that I did not know how to start mongodb to connect to the database

This year I learned a lot about mongodb and node.js and I understood what I needed to do.

With your help I have three steps:

1. Open a console with mongod --dbpath /project/path-do-database/
2. I connected my API to mongodb, passing the right port
3. Open a second console by starting the node.js API with node ornodemon and passing the project's main javascript file.

Answer 1

I know it is probably late, but error logs says it all:

 ERROR: dbpath (/data/db) does not exist.

I belive you need to create /data/db folders or it was created somewhere else. It is already answered here: mongodb Mongod complains that there is no /data/db folder

Answer 2

Basically, you need to have 2 terminals running at the same folder. One for mongoDB, one for your application.

On the first terminal,

1>> npm install -g meanjs
1>> yo meanjs

then fill up your application name, author name, etc.

1>> npm install

Open up a 2nd terminal to start the mongodb server

2>> mongod 

Go back to the first terminal and run it

1>> npm start

Answer 3

You are starting your meanjs app on the same port as your mongodb server (27017). If you do not specify a port for meanjs, it will start on 3000 in a development environment.
