SSL Certification for Websites
---------------------------------

We have to follow this SSL certification for only “apoyar.eu” domain all sites

We have to install the certbot with following command only

• certbot certonly –nginx

• For all websites we are securing should have only TLS 1.2 and 1.3

• We don’t have to use SSL and TLS 1.0 , 1.1

To know, nginx version and certification details we have, go to below path

• cd /etc/nginx

and, run below command

• nginx –V

To know what websites are running on server, go to below path

• cd /etc/nginx/sites-enabled/

and run below command

• grep -rnw '/etc/nginx/sites-available/' -e 'server_name'

For every SSL certification configuration, we have to follow below two redirection

• www --> non-www

• http --> https

for ex.
www.apoyar.eu  http://www.apoyar.eu  https://www.apoyar.eu  https://apoyar.eu

How to create DNS CAA record

• Go to go daddy

• Manage DNS

• Select domain and click on add

• Enter the details as per below
