With neither FleetSSL cPanel or cPanel® AutoSSL supporting DNSONLY servers, we've decided to make a free and convenient packaging of the awesome acmetool project and some custom configuration + hooks for free, automatically renewing SSL on your DNSONLY nameservers.
Ensure you meet the prerequisites:
1. You will be fetching the package from our yum repository:
wget https://cpanel.fleetssl.com/static/letsencrypt.repo -O /etc/yum.repos.d/letsencrypt.repo
2. Install the package
yum -y install letsencrypt-cpanel-dnsonly
3. Wait for the certificate
The issuing and installation process should run as a post-installation step automatically, completing in your terminal within a minute or so. You should now have a valid certificate on port :2087
You typically should not need to do anything after installing the package.
I need to re-install the service certificate that was already issued. You may use the following command:
/usr/local/letsencrypt-cpanel-dnsonly/acmetool test-notify $(hostname)
I want to run renewal by hand or troubleshoot the renewal process. You may use the following command, but acmetool may decline to do anything if the existing certificate is valid and long duration. An automatically-added cron job usually runs this task.
/usr/local/letsencrypt-cpanel-dnsonly/acmetool --xlog.severity=debug reconcile
You may find the full documentation to acmetool on the project website..
I changed my server hostname. A re-install will get you going:
yum -y reinstall letsencrypt-cpanel-dnsonly
Why? Not having an easy SSL solution for DNSONLY servers seemed like a bit of a blind spot. Changing our plugin to work with DNSONLY was too involved (it's not our core use case), using generic Let's Encrypt™ tools by hand was tedious for a large number of servers, so this is the middle ground!
I need help. This project is community supported. This means, you may not email us at FleetSSL about it - sorry, we are not providing technical support! You may open an issue on the Github project if you believe you have found a bug or you would like to contribute code or documentation.
