Christos Hayward asked:
letsencrypt-auto, when run from the command line with e.g.
-d example.com -d www.example.com for arguments, requests interactively whether I want HTTP requests forcibly redirected to HTTPS.
How can I cron this? Can I run it
< input.txt or some form of
yes 2 |? Or does
letsencrypt-auto act differently when it’s not attached to a tty?
First, update to the latest version of
certbot. If you are still calling
letsencrypt-auto then you likely have a very old version that will stop working sooner or later.
All you need to do to renew is call
certbot-auto renew or
certbot renew. Each cert you have obtained already has its own configuration file stored in
/etc/letsencrypt and doesn’t need options explicitly specified again.
Ideally you should be using a
certbot package provided by your Linux distribution. In addition to remaining up to date, these include a systemd timer which you can enable to have the renewal job run automatically.
