How to Configure SSL for Nginx on Ubuntu 24.10

To configure SSL for Nginx on Ubuntu 24.10, follow these simple steps:

Step 1 : Run the following commands to ensure your system is up-to-date:

sudo apt update

Step 2 : If OpenSSL is not already installed, you can install it using:

sudo apt install openssl -y

Step 3 : Create a self-signed SSL certificate for your domain:

sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/example.devtutorial.io.key -out /etc/ssl/certs/example.devtutorial.io.crt

Fill in the required details when prompted.

Step 4 : Create a configuration file for your domain (e.g., example.devtutorial.io):

sudo nano /etc/nginx/sites-available/example.devtutorial.io

Add the following content:

server {
    listen 80;
    server_name example.devtutorial.io;

    # Redirect HTTP to HTTPS
    return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    server_name example.devtutorial.io;

    ssl_certificate /etc/ssl/certs/example.devtutorial.io.crt; # Path to your SSL certificate
    ssl_certificate_key /etc/ssl/private/example.devtutorial.io.key; # Path to your private key

    root /var/www/example.devtutorial.io/html;
    index index.html;

    location / {
        try_files $uri $uri/ =404;
    }
}

Save and close the file.

Step 5 : Create a symbolic link to enable the configuration:

sudo ln -s /etc/nginx/sites-available/example.devtutorial.io /etc/nginx/sites-enabled/

Step 6 : Check for syntax errors in the Nginx configuration:

sudo nginx -t

Step 7 : Apply the changes by restarting Nginx:

sudo systemctl restart nginx

Step 8 : Visit your domain (e.g., https://example.devtutorial.io) in a browser.

If you see a security warning, bypass it since it is a self-signed certificate.

Congratulations! You have successfully configured SSL for Nginx on Ubuntu 24.10.
