1. Introduction to DigitalOcean

DigitalOcean is a cloud infrastructure provider that offers scalable compute platforms with simple and intuitive management tools. It is popular among developers for its ease of use, robust performance, and affordable pricing. DigitalOcean’s Droplets can be configured with various Linux distributions, including Ubuntu, CentOS, and Debian, making it a flexible choice for hosting web servers.

2. Setting Up a DigitalOcean Account

Before creating a web server, you need to set up an account on DigitalOcean.

  • Visit DigitalOcean’s website.
  • Click on “Sign Up” and fill in your details.
  • Verify your email address.
  • Add a payment method; DigitalOcean offers a free trial credit, so you can try their service without immediate charges.
  • Once your account is verified, log in to the DigitalOcean Control Panel.

3. Creating a Droplet (Virtual Server)

A Droplet is a virtual server instance. Here’s how to create one:

  • In the DigitalOcean dashboard, click the Create button, then select Droplets.
  • Choose an operating system. Ubuntu (latest LTS version) is recommended for beginners.
  • Select a plan. The basic plan with 1GB RAM and 1 vCPU is sufficient for a simple web server.
  • Choose a data center region close to your target audience.
  • Add SSH keys (recommended for secure access). If you don’t have an SSH key, you can create one using tools like ssh-keygen on Linux/macOS or PuTTYgen on Windows.
  • Give your Droplet a hostname.
  • Click Create Droplet.

Your Droplet will be ready in a minute or two.

4. Connecting to Your Droplet via SSH

To manage your server, you need to connect via SSH:

  • On Linux/macOS, open a terminal and type:
  ssh root@your_droplet_ip
  • On Windows, use an SSH client like PuTTY and connect to your server’s IP address.

The first time you connect, you may be prompted to confirm the server’s fingerprint. Type “yes” to proceed. You will then enter the root password or use your SSH key for authentication.

5. Installing a Web Server

You can choose between Apache and Nginx, the two most popular web servers.

Installing Apache

Run the following commands:

sudo apt update
sudo apt install apache2

Enable Apache to start on boot:

sudo systemctl enable apache2
sudo systemctl start apache2

Test the installation by opening your browser and navigating to http://your_droplet_ip. You should see the Apache default welcome page.

Installing Nginx

Alternatively, install Nginx:

sudo apt update
sudo apt install nginx

Start and enable Nginx:

sudo systemctl enable nginx
sudo systemctl start nginx

Visit http://your_droplet_ip to see the Nginx welcome page.

6. Configuring Your Web Server

After installation, configure your web server to serve your website files.

For Apache

  • Website files are located in /var/www/html by default.
  • Change ownership to your user for easier file management:
  sudo chown -R $USER:$USER /var/www/html
  • Place your website files (HTML, CSS, JS) in this directory.
  • To customize the server configuration, edit /etc/apache2/sites-available/000-default.conf.

For Nginx

  • Website files are located in /var/www/html as well.
  • Change ownership similarly:
  sudo chown -R $USER:$USER /var/www/html
  • Edit the default server block configuration at /etc/nginx/sites-available/default.
  • Reload Nginx after changes:
  sudo systemctl reload nginx

7. Deploying a Sample Website

Create a simple HTML file to test your server:

echo "<!DOCTYPE html><html><head><title>My DigitalOcean Server</title></head><body><h1>Welcome to My Web Server</h1></body></html>" > ~/index.html
sudo mv ~/index.html /var/www/html/index.html

Refresh your browser at http://your_droplet_ip to see your custom page.

8. Setting Up a Domain Name (Optional)

To make your website accessible via a domain name:

  • Purchase a domain from a registrar.
  • Go to the domain’s DNS settings.
  • Add an A record pointing your domain to your Droplet’s IP address.
  • On your server, configure your web server to recognize the domain:
  • For Apache, create a new site configuration file in /etc/apache2/sites-available/yourdomain.com.conf.
  • For Nginx, create a server block in /etc/nginx/sites-available/yourdomain.com.
  • Enable the configuration and reload the web server.

9. Securing Your Web Server

Security is crucial. Here are basic steps:

  • Create a new user: Avoid using root for daily tasks.
  adduser yourusername
  usermod -aG sudo yourusername
  • Disable root SSH login: Edit /etc/ssh/sshd_config and set PermitRootLogin no.
  • Enable UFW firewall:
  sudo ufw allow OpenSSH
  sudo ufw allow 'Apache Full'    # or 'Nginx Full' if using Nginx
  sudo ufw enable
  • Install SSL with Let’s Encrypt: Use Certbot to enable HTTPS.
  sudo apt install certbot python3-certbot-apache   # For Apache
  sudo apt install certbot python3-certbot-nginx    # For Nginx
  sudo certbot --apache                              # Or --nginx
