Node.js is a free, open-source, and popular JavaScript runtime environment built on Chrome’s V8 JavaScript engine. It’s used for traditional websites and back-end API services.

Apache is an open-source and one of the most popular web servers in the world. You can also use Apache as a frontend proxy server for backend applications including, Node.js.

In this post, we will show you how to configure Apache as a reverse proxy for the Node.js application on Ubuntu 20.04.


  • A fresh Ubuntu 20.04 server on the Atlantic.Net Cloud Platform
  • A root password configured on your server

Step 1 – Create Atlantic.Net Cloud Server

First, log in to your Atlantic.Net Cloud Server. Create a new server, choosing Ubuntu 20.04 as the operating system with at least 2GB RAM. Connect to your Cloud Server via SSH and log in using the credentials highlighted at the top of the page.

Once you are logged in to your Ubuntu 20.04 server, run the following command to update your base system with the latest available packages.

apt-get update -y

Step 2 – Install Node.js

First, you will need to install the required dependencies to your system. You can install them with the following command:

apt-get install curl gnupg2 build-essential wget -y

Once installed, add the Node.js repository with the following command:

curl -sL | bash -

Once the repository is added, run the following command to install Node.js:

apt-get install nodejs -y

Once the Node.js is installed, verify the Node.js version using the command below:

node -v

You should see the following output:


Step 3 – Create a Node.js Application

Next, you will need to create a Node.js application to your server.

First, create a directory for your application with the following command:

mkdir project

Next, change the directory to project and create a nodeapp.js file:

cd project
nano nodeapp.js

Add the following lines:

const http = require('http');
const hostname = 'localhost';
const port = 8000;

const server = http.createServer((req, res) => {
    res.statusCode = 200;
    res.setHeader('Content-Type', 'text/plain');
    res.end('Welcome to Node.js!\n');

server.listen(port, hostname, () => {
    console.log(`Server running at http://${hostname}:${port}/`);

Save and close the file, then run the application with the following command:

node nodeapp.js

If everything is fine, you should get the following output:

Server running at http://localhost:8000/

Press CTRL+C to stop the application.

Step 4 – Create a Systemd Service File for Node.js

Next, you will need to create a systemd service file to manage the Node.js service. You can create it with the following command:

nano /lib/systemd/system/nodeapp.service

Add the following lines:

Description=Node.js Application

ExecStart=/usr/bin/node nodeapp.js



Save the file when you are finished, then reload the systemd daemon to apply the configuration changes:

systemctl daemon-reload

Next, start the nodeapp service and enable it so that it can start automatically at system reboot:

systemctl start nodeapp
systemctl enable nodeapp

Next, verify the status of the nodeapp service by running the following command:

systemctl status nodeapp

You should see the following output:

● nodeapp.service - Node.js Application
     Loaded: loaded (/lib/systemd/system/nodeapp.service; disabled; vendor preset: enabled)
     Active: active (running) since Wed 2021-03-24 11:33:12 UTC; 7s ago
   Main PID: 10551 (node)
      Tasks: 11 (limit: 2353)
     Memory: 7.6M
     CGroup: /system.slice/nodeapp.service
             └─10551 /usr/bin/node nodeapp.js

Mar 24 11:33:12 ubuntu2004 systemd[1]: Started Node.js Application.
Mar 24 11:33:12 ubuntu2004 node[10551]: Server running at http://localhost:8000/

Step 5 – Configure Apache as a Reverse Proxy

First, install the Apache package with the following command:

apt-get install apache2 -y

Next, create an Apache virtual host configuration file for Node.js:

nano /etc/apache2/sites-available/nodeapp.conf

Add the following lines:

<VirtualHost *:80>
    ServerName your-server-ip

    ProxyRequests Off
    ProxyPreserveHost On
    ProxyVia Full

    <Proxy *>
        Require all granted

    ProxyPass /
    ProxyPassReverse /

Save and close the file, then enable the virtual host configuration file:

a2ensite nodeapp.conf

Next, disable the default virtual host configuration file and enable the required proxy modules with the following command:

a2dissite 000-default 
a2enmod proxy proxy_http rewrite headers expires

Finally, restart the Apache service to apply the changes:

systemctl restart apache2

Step 6 – Access Node.js Application

Now, open your web browser and access your Node.js application using the URL http://your-server-ip. You should see your application in the following page:


In the above guide, you learned how to configure Apache as a reverse proxy for the Node.js application. This will help you to host your Node.js application from the local system to the production environment – try it on your dedicated hosting account from Atlantic.Net.
