The plugin is distributed in RPM form as part of a yum repository for CentOS 6 and 7.
- Root SSH access to WHM
- i386 or x86_64 CentOS 6 or 7 (5 is not supported)
- WHM/cPanel of at least STABLE version or newer (CloudLinux and LSWS compatible)
Add the letsencrypt package repository:
wget https://cpanel.fleetssl.com/static/letsencrypt.repo -O /etc/yum.repos.d/letsencrypt.repo
Next, install the plugin through yum via
yum -y install letsencrypt-cpanel
The repository will install the plugin to the system - this might take a minute.
Now that the installation is complete, you should be able to login to any cPanel server on that server, and see the “Let’s Encrypt™ SSL” icon on the home screen. You should be able to immediately issue certificates, provided that the domain actually points to the server.
