I wrote some nodejs services in my ubuntu local.Now I want to deploy my nodejs services into nginx server in my seperate VM.I set up the nginx in my virtual machine.How can I pull my nodejs services to nginx server and how to connect these api's through postman. I getting confusion at nginx config file.
You should setup a reverse proxy with nginx to redirect the traffic to you node application. Install node on your VM, copy your application and install all the dependencies using npm install. Afterwards, you should start the node application using node index.js where index.js is the entry point of your application. You could also use a process manager such as pm2 to start the application. Then, you have to setup the reverse proxy with nginx which is redirecting the traffic to the port of your application. (In your sample code 3000). The application should now be available on the IP of your VM. Below you find a minimal example configuration for nginx.
server {
listen 80;
server_name domain.com;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}

I am trying to deploy a nuxt blog to a virtual private server that runs nginx.
The blog is supposed to be accessible when I browse to https://exampledomain.com/articles
I have managed to run npm run dev on the server successifully... The app is running on localhost:3000 on the server....
I need to set a reverse proxy on the server to redirect all requests from https://exampledomain.com/articles/ to localhost:3000
I have tried this twice and its failing.... When I browse https://exampledomain.com:3000 the app is loading forever.... when I go to https://exampledomain.com/articles it says "Page not working", or "Internal server error"
Kindly assist
This could be happening due to incorrect configuration.
Try
sudo nano /etc/nginx/sites-available/your-domain.com
Remember to change the your-domain.com to your desire domain
server {
listen 80;
listen [::]:80;
index index.html;
server_name your-domain.com;
location / {
proxy_pass http://localhost:3000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
i have simple nodejs app running on ec2 instance with nginx configs
when tried to access the app from browser it give me "ec2-18-223-0-201.us-east-2.compute.amazonaws.com refused to connect."
when trying to curl it from VM
using curl http://localhost:3000 it works correctly, however when trying curl http://127.0.0.1:3000 it give me this output
Found. Redirecting to https://127.0.0.1:3000/
here's my nginx configs
upstream test{
server 127.0.0.1:3000;
}
server {
listen 80;
server_name ec2-18-223-0-201.us-east-2.compute.amazonaws.com www.ec2-18-223-0-201.us-east-2.compute.amazonaws.com;
location / {
client_max_body_size 20M;
client_body_buffer_size 128k;
proxy_pass http://test;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
One thing that should be clear before the actual problem. Is there in redirect policy in node app that returns below output?
curl http://127.0.0.1:3000 it gives me this output
Found. Redirecting to https://127.0.0.1:3000/ because redirection is
expected from Nginx, not from node app.
But I am sure the problem is with Nginx not with Node app as it is able to respond on a local port 3000.
refused to connect to connect mean that the server not running at all or the port may disable from the firewall.
Two possible reasons:
The Port 80 is not allowed in Security Group of the instance so allow 80 in the security group of AWS instance.
The Nginx is not running. Check the log under tail -f /var/log/nginx/error.log and the reason might be the log name of the DNS in the sever section.
So therefor two Suggestion for Nginx config
update your Nginx config to support long DNS name
vim /etc/nginx/nginx.conf and add value under http section in the config
http {
server_names_hash_bucket_size 512;
....
}
2. Remove redundent name from the config, its not be the reason but you should remove server_name ec2-18-223-0-201.us-east-2.compute.amazonaws.com www.ec2-18-223-0-201.us-east-2.compute.amazonaws.com;
I bought ubuntu server in digitalocean.
I am connecting my server IP through ssh on my terminal and i create a small node app and after starting the app, I can able to see my app running on my http://myipaddress:nodeport
How i can i connect my domain to this?
I bought free domain from freenom for testing purpose.
By following some tutorials i make a /etc/nginx/sites-available folder into my server and create a file called default and write code like this
server {
listen 80;
server_name sameer.tk; // i bought this domain from freenom
location / {
proxy_pass http://my_private_ip:3004 //with nodeport
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
But if i hit sameer.tk after the setup its not working, i even restart my nginx.
You no need any nginx for node server.
You may run node server as 80 port and open 80 port in network security group.
After that, you should point domain to your instance public ip address in your domain management panel.

I have developed Rest API using Node JS, Express and MongoDb.
I have istalled MongoDB into one machine with Ubuntu Server OS and Node JS App on machine with Ubuntu Server OS.
Now i need to deploy to Production enviroments with a reverse proxy.
I have seen this post as example:
Deploy Node JS
Now my question is: the reverse proxy server using Nginx must be deploy on a separete machine? Instead Nginx is possible to use Apache?
Thanks for your help
You can deploy nginx on same machine.So your setup will be nginx listening to 80 port of the machine for incoming requests and redirecting all requests to you application as per you have specified in nginx configuration.
if you are deploying nginx on same machine and having application 8080. you can do some thing like this.
server {
listen 80;
server_name example.com;
location / {
proxy_pass http://localhost:8080;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
and if you can configure apache to redirect request to your application you can replace nginx with apache.(but i have not worked with apache so as per me above configurations works.but if you want some help you can read this one link)
I have a node.js backend application running on port 1337 and i want to deploy it to my nginx server so i can get access to my backend from another computer and other netwroks.
i tried this in sites_availables and i enabled this configuration :
server {
listen 80;
server_name x.x.x.x(my server adrress);
location /node {
proxy_pass http://localhost:1337;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
}
}
then i restarted nginx
sudo service nginx restart
now i'm trying to reach x.x.x.x/node through my browser and i get 501 bad getaway.
The reverse proxy pipe from nginx to node is being broken because your path in the nginx config /node does not exist on your node application. You either need to implement that route, or do a rewrite to have nginx rewrite the path when proxying (check out this question: https://serverfault.com/questions/586586/nginx-redirect-via-proxy-rewrite-and-preserve-url)
