To install lets-encrypt certificate on a machine for use with apache (httpd) use:

1. dnf -y install epel-release mod_ssl
2. dnf -y install certbot python3-certbot-apache
3. certbot apache mode works only when NameVirtualHost is enabled and appropriate VirtualHost are created in apache. If this is not present then add configuration similar to below in '/etc/httpd/conf/httpd.conf' at bottom:

   NameVirtualHost *:80
   
   <VirtualHost *:80>
       ServerAdmin saurabh@sbarjatiya.com
       DocumentRoot /var/www/html
       ServerName server.example.com
       ErrorLog logs/server.example.com-error_log
       CustomLog logs/server.example.com-access_log combined
   </VirtualHost>
   

4. Then request certificate via:

   certbot --apache

   We may have to give email address, accept agreement and optionally agree to share details.

   After that we need to select virtualhosts for which we want to request TLS certificate.
