How to Install Let's Encrypt SSL in Apache on Ubuntu 22.04

To install Let's Encrypt SSL on Apache in Ubuntu 22.04, you can use the Certbot tool. Certbot is a free and automated tool for obtaining and renewing SSL certificates. Here are the steps:

Step 1 : Install Certbot

First, you need to install the Certbot package. Open a terminal and run the following commands:

sudo apt update
sudo apt install certbot python3-certbot-apache

Step 2 : Configure Apache for the New Domain

sudo nano /etc/apache2/sites-available/example.devtutorial.io.conf

Add a VirtualHost block for your domain:

<VirtualHost *:80>
    ServerAdmin webmaster@example.devtutorial.io
    ServerName example.devtutorial.io
    DocumentRoot /var/www/html/example.devtutorial.io/public_html

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    <Directory /var/www/html/example.devtutorial.io/public_html>
        Options -Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

Replace /var/www/html/example.devtutorial.io/public_html with the actual path to your website's root directory.

Step 3 : Enable the New Virtual Host

Enable the new virtual host configuration:

sudo a2ensite example.devtutorial.io.conf

Step 4 : Restart Apache

Restart Apache to apply the changes:

sudo systemctl restart apache2

Step 5 : Obtain SSL Certificate

- Now, run Certbot for the new domain to obtain an SSL certificate:

sudo certbot --apache -d example.devtutorial.io

- Certbot will guide you through the process, enter your email, and agree to the terms.

Step 6 : Restart Apache

After obtaining and configuring the SSL certificate, restart Apache to apply the changes:

sudo systemctl restart apache2

Step 7 : Test Renewal for the New Domain

As before, test the renewal process for the new domain:

sudo certbot renew --dry-run

Step 8 : Verify SSL Configuration: Open your web browser and enter the URL for your domain.

You've successfully configured Apache and obtained an SSL certificate for the new domain using Let's Encrypt and Certbot. Your website should now be accessible over HTTPS.
