Let’s Encrypt is a certificates authority that gives unfastened SSL certificate for internet sites. It was once introduced in 2014 with the objective of all internet sites being safe and HTTP.
In addition to providing SSL certificate, it additionally is helping implementation and automated renewal of certificate. Let’s Encrypt is the arena’s biggest certificates authority, utilized by greater than 250 million internet sites.
When penning this submit, Let’s Encrypt helps the automated set up of certificate on Apache, Nginx, Plex, and Haproxy.
Here, we can see find out how to set up Let’s Encrypt SSL Certificate in Apache on Debian 11.
Prerequisites
Install Apache Webserver
I like to recommend you put in the Apache webserver to your machine sooner than you continue additional.
READ: How to Install LAMP Stack on Debian 11
OR
Use the apt command to put in the Apache webserver.
sudo apt replace sudo apt set up -y apache2
Enable Modules
Use the under command to allow SSL and rewrite modules.
sudo a2enmod ssl rewrite
Create Virtualhost
First, we can want to create an Apache digital host to serve the HTTP model of your web page.
sudo nano /and so forth/apache2/sites-available/www.holhol24.internet.conf
Use the under configuration on your web page. Do take into accout to switch the values according to your requirement. If you don’t use the www subdomain, you’ll be able to take away the ServerAlias.
ServerName holhol24.internet ServerAlias www.holhol24.internet ServerAdmin admin@holhol24.internet DocumentRoot /var/www/html/www.holhol24.internet ErrorLog ${APACHE_LOG_DIR}/www.holhol24.net_error.log CustomLog ${APACHE_LOG_DIR}/www.holhol24.net_access.log blended /var/www/html/www.holhol24.internet> Options FollowSymlinks AllowOverride All Require all granted
Once you may have created the digital host configuration record, allow the website.
sudo a2ensite www.holhol24.internet
Next, create a root listing to carry your web page’s information.
sudo mkdir -p /var/www/html/www.holhol24.internet/
Then, trade the possession and staff of the listing.
sudo chown -R www-data:www-data /var/www/html/www.holhol24.internet/
Finally, position the check HTML record at the record root of the web page.
echo "This is a test site @ www.holhol24.net" | sudo tee /var/www/html/www.holhol24.internet/index.html
Restart the Apache carrier to re-read the configurations.
sudo systemctl reload apache2
Create / Update DNS Record
To generate a Let’s Encrypt SSL certificates, it is very important level your area in your server IP. So, move in your area registrar and create an A/CNAME file on your area. For instance, the under symbol presentations the A/CNAME file for the area www.holhol24.internet.
NOTE: After making adjustments within the DNS file, it is very important look ahead to a couple of mins to hours relies on the TTL you place for the DNS file.
Install Let’s Encrypt SSL Certificate in Apache
Install Certbot
The Certbot ACME shopper handles the certificates issuance and set up without a downtime. It is out there as a snap bundle for Debian working machine. So, first, set up the Snapd bundle.
sudo apt replace sudo apt set up -y snapd
Then, replace the snapd to the newest model.
sudo snap set up core; sudo snap refresh core
Finally, set up the Certbot shopper the use of the snap command and hyperlink it so as to invoke the certbot command from any place irrespective of the present running listing.
sudo snap set up --classic certbot sudo ln -s /snap/bin/certbot /usr/bin/certbot
Install Let’s Encrypt Certificate
Use the certbot command to create a Let’s Encrypt certificates and configure Apache to make use of the certificates.
sudo certbot --apache
You will want to apply the interactive urged and set up the certificates. Since I’ve created a digital host for each holhol24.internet and www.holhol24.internet, I can additionally want to set up SSL certificate for each domain names. Then, I can redirect the entire site visitors to www.holhol24.internet by way of rewrite laws.

Once you turn on HTTPS on your area, the Certbot shopper will position important rewrite laws to redirect site visitors from HTTP to the HTTPS website.
In my case, it has positioned two laws for under redirections.
- http://holhol24.internet >> https://holhol24.internet
- http://www.holhol24.internet >> https://www.holhol24.internet
As you’ll be able to see, the primary redirection isn’t reached to the www HTTPS model of the area. So, chances are you’ll want to apply the under segment to set it up.
Redirect non-www HTTP requests to www HTTPS with Apache
You might need to configure the Apache webserver to redirect the site visitors from the non-www HTTP website to the WWW HTTPS website, I.e., http://holhol24.internet >> https://www.holhol24.internet.
Edit the Let’s Encrypt SSL digital host record (no longer your unique digital host record).
sudo nano /and so forth/apache2/sites-available/www.holhol24.net-le-ssl.conf
Add the under laws sooner than the . Change the area identify as in line with your requirement.
# Redirect NON-WWW HTTP to WWW HTTPS
RewriteEngine on
RewriteCond %{SERVER_NAME} =holhol24.internet
RewriteRule ^ https://www.holhol24.internet%{REQUEST_URI} [END,NE,R=permanent]1,L]
Then, restart the Apache carrier.
sudo systemctl restart apache2
Verify Let’s Encrypt Certificate
You can check the Let’s Encrypt certificates by means of visiting your web page.
http://your-http-web-site
OR
https://your-https-web-site
You will have to get the HTTPS model of your website now.
Test SSL Certificate
Test your Let’s Encrypt SSL certificates for any problems and its safety rankings by means of going to the under URL.

Renew Let’s Encrypt Certificate
As , Let’s Encrypt certificate have a validity of 90 days, and you have got to make sure they’re renewed on time. The renewal procedure is now automatic and because of the systemd carrier supplied by means of the Certbot shopper. So, you wouldn’t have to resume them manually.
However, it is suggested to check certificates renewals by means of simulating the automated renewal of SSL certificate by means of working the under command.
sudo certbot renew --dry-run
Output:

If the output confirms that the check renewal is a success, the automated renewal will occur as anticipated.
Conclusion
That’s All. I am hoping you discovered find out how to Install Let’s Encrypt SSL Certificate in Apache on Debian 11.
