If you want certs only, do this: sudo yum install epel-release sudo yum install certbot sudo letsencrypt certonly -a standalone -d srv08.karloluiten.nl crontab -e add: 30 */12 * * * /usr/bin/letsencrypt renew >> /var/log/le-renew.log (add the previous logfile in /etc/logrotate.d/syslog for example, or make your own) certs are now in /etc/letsencrypt/live/srv08.karloluiten.nl/cert.pem
