How To Secure Apache with Let’s Encrypt on Ubuntu 22
How To Secure Apache with Let's Encrypt on Ubuntu 22.04 || MANOJ DAMOR || CODING FUNDA
As of my last knowledge update in September 2021, I can provide you with a general guide on how to secure an Apache web server with Let’s Encrypt on Ubuntu. Please note that software versions and procedures may have changed since then. I recommend checking the official Let’s Encrypt and Ubuntu documentation for any updates or changes specific to Ubuntu 22.04.

Here are the steps to secure Apache with Let’s Encrypt on Ubuntu:
Step 1: Update Your Server
sudo apt update
sudo apt upgrade
Step 2: Install Apache
If you haven’t already installed Apache, you can do so using the following command:
sudo apt install apache2
Step 3: Install Certbot
Certbot is a tool provided by Let’s Encrypt to obtain and manage SSL certificates for your server. Install Certbot and the Apache Certbot plugin:
sudo apt install certbot python3-certbot-apache
Step 4: Configure Apache
Certbot can automatically configure Apache to use the SSL certificate. However, make sure your Apache default configuration is ready. You can create or modify an Apache configuration file for your site in the /etc/apache2/sites-available/ directory, typically with a .conf extension.
For example, you can create a new configuration file:
sudo nano /etc/apache2/sites-available/your-site.conf
Inside the configuration file, configure your virtual host to listen on port 80 and include the SSL certificate lines like this:
<VirtualHost *:80>
ServerAdmin [email protected]
ServerName yourdomain.com
DocumentRoot /var/www/your-site-directory
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Save the file and exit.
Step 5: Obtain SSL Certificate
Use Certbot to obtain an SSL certificate for your domain and configure Apache:
sudo certbot --apache -d yourdomain.com
Certbot will prompt you to provide an email address and agree to the terms of service. It will also ask if you want to redirect HTTP traffic to HTTPS; it’s a good idea to enable this option.
Step 6: Automatically Renew Certificates
Let’s Encrypt certificates expire after 90 days. To automatically renew them, Certbot installs a cron job. You can test the renewal process with this command:
sudo certbot renew --dry-run
Step 7: Adjust Your Firewall (if applicable)
If you are using a firewall, such as UFW, make sure to allow HTTPS traffic:
sudo ufw allow 'Apache Full'
Step 8: Test Your Configuration
Restart Apache to apply the changes:
sudo systemctl restart apache2
Visit your website using HTTPS (https://yourdomain.com) to ensure that the SSL certificate is working correctly. You should see a padlock icon in your browser’s address bar.
Your Apache web server should now be securely configured with Let’s Encrypt SSL certificates on Ubuntu 22.04. Keep in mind that SSL/TLS best practices may evolve, so it’s essential to stay updated with the latest recommendations and security advisories for your specific server configuration.
