Step 1: Install Let’s Encrypt SSL
HTTPS is a protocol for secure communication between a server (instance) and a client (web browser). Due to the introduction of Let’s Encrypt, which provides free SSL certificates, HTTPS are adopted by everyone and also provides trust to your audiences.
Here we will install Certbot to install Let’sEncrypt SSL using Snap.
sudo apt update
sudo apt install snapd -y
sudo snap install core
sudo snap refresh core
Install Certbot tool.
sudo snap install --classic certbot
Configure Certbot to be executable as as a command.
sudo ln -s /snap/bin/certbot /usr/bin/certbot
Now we have installed Certbot to install Let’s Encrypt for Debian 11.
Execute the following command to install your certificates.
sudo certbot --apache --agree-tos --redirect -m youremail@email.com -d domainname.com -d www.domainname.com
Select the appropriate option and hit Enter
This command will install Free SSL, configure redirection to HTTPS and restarts the Apache server.
Step 2: Renewing SSL Certificate
Certificates provided by Let’s Encrypt are valid for 90 days only, so you need to renew them often. So, let’s test the renewal feature using the following command.
sudo certbot renew --dry-run
This command will test the certificate expiry and configures the auto-renewable feature.
Step: 3: Test the Setup
Once you have done the able steps you can create a new test HTML file in your web directory.
sudo nano /var/www/html/domainname/public/index.html
Paste the below code inside the file.
<!DOCTYPE html>
<html>
<body>
<h1>Test page with HTTPS</h1>
</body>
</html>
Save the file.
Now go ahead and check your domain name in browser (domainname.com).
You will see that your domain got redirected to HTTPS and see the HTML output.
