You have read the following tutorial:

Example of the subdomain used in this tutorial:

Step 1: Create an ‘A’ record for the subdomain

  1. Go to your DNS settings page and open the records where you have main domain DNS settings.
  2. Now add an A record with subdomain in Enter Name field (only add subdomain part. For example if you are going to create a subdomain then only enter apps and in the IP address field, enter the droplet IP.

Step 2: Create subdomain directory and index file

Create the subdomain and add the index file:

# Create directory
sudo mkdir $subdomain_dir
# Create index.html
sudo touch $subdomain_dir/index.html

Edit the index file content as you want. The content looks like this:

<!DOCTYPE html>
<title>Welcome to Example Appstore!</title>
    body {
        width: 35em;
        margin: 0 auto;
        font-family: Tahoma, Verdana, Arial, sans-serif;
<h1>Welcome to Example Appstore!</h1>
<p>This site is under active development.</p>

Step 3: Create NGINX server block for the subdomain

This enables the subdomain in the NGINX server.

# 1. Copy the default config for the new subdomaine
sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/$mysubdomain
sudo ln -s /etc/nginx/sites-available/$mysubdomain /etc/nginx/sites-enabled/$mysubdomain
# 2. Open the config file
sudo nano /etc/nginx/sites-available/$mysubdomain
# 3. Edit the file
# The content should look something like this
server {
        listen 80;
        listen [::]:80;
        root /var/www/apps;
        index index.html;
# 4. Restart NGINX
sudo service nginx restart

Step 4: Add SSL certificate for security

# Obtain an SSL Certificate
sudo certbot --nginx -d $mysubdomain

Step 5: Access to the subdomain
