How To Create an SSL Certificate on Apache for Ubuntu 24.04

In today’s digital landscape, securing your website with HTTPS is essential for protecting user data and enhancing trustworthiness. One of the key elements in achieving this security is the implementation of an SSL (Secure Socket Layer) certificate. This guide will walk you through the steps necessary to create an SSL certificate on an Apache server running Ubuntu 24.04.

What is an SSL Certificate?

An SSL certificate encrypts data exchanged between the server and the client’s browser, ensuring that sensitive information remains confidential. It is vital for e-commerce sites, login pages, and any platform that handles private user data.

Prerequisites

Before you get started, make sure you have:

1. A server running Ubuntu 24.04.
2. Apache installed and configured. You can install Apache using the following command:

   sudo apt update
   sudo apt install apache2

3. Access to the terminal and root or sudo privileges.
4. Domain name pointing to your server’s IP address.

Step 1: Install Certbot

For automatically managing SSL certificates, we will use Certbot, which is a tool from the Electronic Frontier Foundation (EFF). It makes the process of obtaining and renewing SSL certificates easy.

1. First, update your package list:

   sudo apt update

2. Now install Certbot along with the Apache plugin:

   sudo apt install certbot python3-certbot-apache

Step 2: Obtain an SSL Certificate

With Certbot installed, obtaining an SSL certificate is straightforward.

1. Run the following command to obtain the certificate:

   sudo certbot --apache

2. You’ll be prompted to enter your email address. This will be used for urgent notices regarding your certificate (e.g., expiration).
3. Accept the terms of service and choose whether to share your email with the EFF.
4. Certbot will automatically detect the available Apache configurations and will prompt you to select the domain(s) for which you want to enable HTTPS.
5. After making your selection, Certbot will:

• Obtain the SSL certificate from Let’s Encrypt.
• Automatically configure Apache to use the new certificate.
• Provide options for redirecting HTTP traffic to HTTPS.

Once complete, you should see a success message indicating that your SSL certificate has been installed.

Step 3: Verify SSL Installation

To check that your SSL certificate is installed correctly, visit your website using https://yourdomain.com. You should see a padlock icon in the address bar, indicating that the connection is secure.

You can also verify your SSL certificate using online tools like SSL Labs’ SSL Test.

Step 4: Set Up Auto-Renewal

Let’s Encrypt certificates are valid for 90 days. However, Certbot can automatically renew them. The installation process typically sets up a cron job for automatic renewals, but you can manually verify this:

1. Test the renewal process with:

   sudo certbot renew --dry-run

If successful, you don’t need to take further action as Certbot will automatically renew your SSL certificates.

Conclusion

Implementing an SSL certificate on your Apache server running Ubuntu 24.04 enhances the security of your website and builds trust with your users. With tools like Certbot, managing SSL certificates becomes a hassle-free process. Always ensure your certificates are up-to-date to maintain optimal security for your site.
