Question
Unable to setup certbot properly with nginx + rails
According to the article https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-16-04
I’m running command to test it:
$ sudo certbot renew --dry-run
And get this:
WARNING:certbot.renewal:Attempting to renew cert from /etc/letsencrypt/renewal/my_website.com.conf produced an unexpected error: At least one of the (possibly) required ports is already taken.. Skipping.
** DRY RUN: simulating 'certbot renew' close to cert expiry
** (The test certificates below have not been saved.)
All renewal attempts failed. The following certs could not be renewed:
/etc/letsencrypt/live/my_website.com/fullchain.pem (failure)
** DRY RUN: simulating 'certbot renew' close to cert expiry
** (The test certificates above have not been saved.)
It’s because nginx is running. But: how is it supposted to work? Stopping nginx and my website twice a day to check and possibly renew a certificate won’t be a wise way to go
How to fix it?
I’m using nginx + rails.
In cron I have this job:
$ sudo certbot renew

when I stop nginx and run the same command, it works. But again, I don’t want my website to be offline twice a day, even for a short period of time, due to certbot.
correction: in cron I have this job:
