If they're different, restart or reload the web server. Check whether the certs are different (i.e renewed) using sha256sum.The tarball is copied to the private server using scp and extracted to /etc/letsencrypt/live/$DOMAIN.It assumes your certs are located in /etc/letsencrypt/live/$DOMAIN You'l need to make sure you have the correct SSH keys configured so that the SSH commands can run without user interaction. Connect to your remote host via SSH and obtains a tarball of your remote SSL certs.Set up a script renew-letsencrypt-certificates.sh on your private server to run automatically.

I have a separate article about how to use certbot.
Do this separate to your private server.Ĭonfigure certbot to auto renew your SSL certificates as you normally would. You'll need your domain name with a web server accessible online, which could be serving a 404 response, or just an empty page. Here's an example of how we can get around this and use HTTP-01 challenge. We'll assume your internal network's web server is not accessible from the internet and that you're running your own DNS server pointing a A record (or CNAME) of to an internet facing server. It can also be a slow process since you may need to wait for the TTL for your domain. The alternative is a DNS challenge, which requires a DNS provider with an API interface. Let's Encrypt needs to access which it won't be able to do if your internal or private server is not internet facing. If you have a web site on an internal network that is not accesible by a public URL, then the most popular HTTP-01 challenge for Let's Encrypt is not going to work. Use a script like renew-letsencrypt-certificates.sh to copy the SSL certs from the remote machine to our local private machine.Remote VPS uses certbot to renew SSL certificates as normal.
This can be served as an empty site or just as a 404 response. Domain must have a DNS A record pointing to a public facing web server so Let's Encrypt can find it for the HTTP-01 challenge.Use internet facing domain on an internal network, I normally use subdomains for this.
