}
access_log /var/log/nginx/www.holhol24.internet.get admission to.log;
error_log /var/log/nginx/www.holhol24.internet.error.log;
location ~ .php$ {
come with fastcgi_params;
fastcgi_intercept_errors on;
fastcgi_pass unix:/run/php/php7.4-fpm.sock;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
}

Once you might have created the digital host configuration document, create a root listing to carry your web page’s information.
sudo mkdir -p /usr/percentage/nginx/www.holhol24.internet/
Then, exchange the possession and team of the listing.
sudo chown -R www-data:www-data /usr/percentage/nginx/www.holhol24.internet/
Finally, position the check HTML document at the file root of your area.
echo "This is a test site @ www.holhol24.net" | sudo tee /usr/percentage/nginx/www.holhol24.internet/index.html

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 Nginx to make use of the certificates.

Redirect non-www HTTP requests to www HTTPS with Nginx (non-compulsory)
You might love to configure the Nginx server 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.
sudo nano /and so forth/nginx/conf.d/www.holhol24.internet.conf
Add the underneath data on the finish of the document.
# Redirect NON-WWW HTTP to WWW HTTPS
server {
if ($host = holhol24.internet) {
go back 301 https://www.holhol24.internet$request_uri;
}
server_name holhol24.internet;
pay attention 80;
go back 404;
}
Then, restart the Nginx carrier.
sudo systemctl restart nginx
Verify Let’s Encrypt Certificate

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 scores via going to the underneath URL.

Renew Let’s Encrypt Certificate
Let’s Encrypt certificate have a validity of 90 days, and it’s extremely really helpful to resume the certificate earlier than they expire. Thanks to the systemd carrier, which runs two times an afternoon and routinely renews certificate which can be about to run out.
But, I like to recommend you run the underneath command to simulate the automated renewal of your certificates.
sudo certbot renew --dry-run
Output:
