I am trying to access Mongodb in the virtualbox hosted Ubuntu. When I am developing app in Ubuntu, I used "meteor create {app_name}"
I didnt change the default Mongodb. So when I am running Meteor app using "meteor" command, I cant access the mongodb.
In my Robomongo app in Windows, I am using this credentials,
"192.168.1.13:3001" as host and port. But It says "failed to connect".
What Do i need to do to connect to my mongodb?
Hey After doing some digging I find out the solution.
steps you need to follow:
Go to the following path cd /etc
There you will find a file called mongod.conf open this file with the help of
sudo vim mongod.conf
3.You will be in a file type i and find bindIp written over there.
4.now you need to change your bindIp of mongodb to 0.0.0.0
5.type ctrl +c then :wq // write and quite
6.sudo service mongod restart
7.Go to your robomongo and create connection and in address field just type your ip (192.168.1.13) // no port number is required in which you are running the code port will be default port on which mongodb runs 27017
I have found that using no bind ip in mongod.conf and adding localhost 127.0.0.1 to the hosts.conf works

I'm trying to install a node.js server for a sentiment analysis service with my Twitter account that retrieve the tweets on my profile and provides a statistical output and saves them on a Mongo db istance.
I have uploaded my node.js code on an AWS virtual machine with an public IP address and with the permission to create an endpoint with HTTP and HTTPS protocols.
I have installed successfully the node.js code on AWS virtual machine with Windows Server 2019 OS, with the npm install -g -n command with 0 dependencies errors, and when I try to connect to the AWS virtual machine with http://ip_public_address:8080 I get the error "impossible to connect - err-connection_timeout".
This is the link to the github project that I need to install and to work on AWS virtual machine:
https://github.com/thisandagain/sentiment
Maybe I am confused about how to connect with the index.html page via AWS virtual machine and I don't know if this page must be retrieved with a IP public address or localhost parameter and what is required, at node.js level code, in order to enable the AWS virtual machine to respond to my browser with the content of index.html page.
Please can you give me advices about to implement successfully this project?
Thanks
Filippo
You don't mention security groups in your question at all, so the likely cause is that you never opened port 8080 in the security group assigned to the EC2 instance. You may also need to open that port in the Windows firewall on that server.
I am learning node.js in an online course to build up a web server and app
before the teaching started, the teacher told me to set up your coding environment, and it got a direction to told me what to do step by step.
Because I using Chromebook, So I started an aws ec2 serve which is ubuntu 18.04 and using cloud9 for my ide
I installed node.js successful on the ec2
And the direction told me to type on those on the terminal
git clone https://github.com/OpenClassrooms-Student-Center/5614116-front-end-app.git frontend
You can then do the following:
cd frontend
npm install
ng serve
This will install all the dependencies needed by the front end app and will launch the development server. Now, if you navigate to http://localhost:4200 , you should see the following (assuming you've followed the steps above successfully):
the direction say if I successfully followed the step, will see something on http://localhost:4200
On the terminal, at last show me
ℹ ｢wdm｣: Compiled successfully.
But how can I connect to http://localhost:4200 which was an ec2?
I tried using IP:4200, the browser keeps on loading the page and nothing shows up on the browser
－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
I found out that the program that teacher gave me to install set the URL to http://localhost:4200
because cloud9 says the program was running, but running at a URL call http://localhost:4200
what should I do？
Localhost refers to your local machine. But as mentionedd that your node.js running on ec2 and want to connect to it from your browser, get the IP of the ec2 and type in your browser- IP:4200
And it should work
The only problem here is you have to add port 4200 in your aws ec2 instance security group to allow inbound traffic.
STEPS:
1. Go to your EC2 instance.
2. Click security group from Description below.
3. Click Inbound then Edit.
4. Click Add Rule
5. Select Custom TCP , Port - 4200 , IP - 0.0.0.0/0
6. Then SAVE.
After that try <EC2-IP:Port> in your browser it will work fine.
EDIT
I think the problem might be that the WebSocket connection does not go through the proxy node.js. How to authorize the connection of the WebSocket?
I have a web app hosted on a nodeJS server. On the same vm I also have a shiny serveur hosting an app. I use node to redirect traffic to port 3838 (shiny) when a somes URL are requested.
I use this code on node :
app.use('/the-shiny-app', proxy({target: 'http://localhost:3838', changeOrigin: true}));
With this setting everything works fine on the shiny app when I go on mydomain/the-shiny-app/* except when I try to run code in a code box.
When I try to run code I get this error on the chrome console :
Connection closed. Info: {"type":"close","code":4503,"reason":"The application unexpectedly exited","wasClean":true}
An example of what I mean by code box :
if I do not use node.js and I redirect the traffic (on OS level) from port 80 directly to 3838 everything works fine.
sudo iptables -A PREROUTING -t nat -p tcp --dport 80 -j REDIRECT --to-ports 3838
I do not know exactly what kind of exchange is made between the browser and the shiny server when we run code, but maybe the protocol used is blocked by node.js.
I found the problem. As Antony Gibbs said you need to setup a WebSocket upgrade. I'm using http-proxy-middleware you cans find the doc here : https://github.com/chimurai/http-proxy-middleware
So I've deployed my meteor app, and have it up and running on an instance.
I've used the following environment variables:
MONGO_URL='mongodb://localhost:27017/meteor'
ROOT_URL='http://<my static ip>'
PORT=3000
And I run the program using the following command:
node bundle/main.js
It prints my "Meteor is starting up" that is printed using the console.log command, and then doesn't error out, but when I navigate to http://< my static ip >:3000 in a browser, I get an ERR_CONNECTION_REFUSED result.
My open mongod terminal says it's connecting fine to the MongoDB database.
Does anyone have any ideas on how to start debugging this issue?
Thanks.
In server you don't need to run meteor application on port 3000. You can run it on port 80 if the port is not being used by any other program.
If you are using port 80 make sure port 80 is opened by the network security rules.
If you are using port 3000 or any other port you will have to make sure that port is opened by the network security rules as above. Additionally you will have to mention the IP in your url, like http://<your_ip>:<port>
I've downloaded a sample socket project from github https://github.com/appcoda/SocketIOChat
I'm using EICapitan and I've installed node js and I've also setup the IP in the sample var socket: SocketIOClient = SocketIOClient(socketURL: NSURL(string: "http://192.168.1.2:3000")!)
When I run node index.js command on terminal it shows Listening on *:3000 But when I run the sample app enter a name to connect user I dont receive any message like user connected. Is there something that I'm missing, I'm a beginner to node.js and socket.io. Any help is appreciated.
Seems like you are trying connect to incorrect ip address.
Get your inet ip from ifconfig and place it to SocketIOClient. I would recommend you to use localhost or 127.0.0.1 for development instead of inet address
