The plugin is distributed in RPM form as part of a yum repository for CentOS and AlmaLinux.


Please note: cPanel DNSONLY servers are currently NOT supported, please use our FleetSSL DNSONLY package instead.

Installation procedure

Install the licence file

Licence Type Instructions
Trial Users Trial users may ignore this step, as a 72-hour duration trial licence will be downloaded automatically for you.
Purchased Licence You will have received a licence file by email. Save your issued licence file as /etc/letsencrypt-cpanel.licence and chmod to 0400. If you received a file ending in .json, rename the file to letsencrypt-cpanel.licence.

If you are upgrading from a trial licence to a paid licence, save/overwrite the issued licence file as above. After installing a new licence file, you will need to restart the background service with the following command: service letsencrypt-cpanel restart

Install the plugin:

Instructions for: CentOS, RHEL, AlmaLinux and other EL derivatives

wget -O /etc/yum.repos.d/letsencrypt.repo ;
yum -y install letsencrypt-cpanel

Instructions for: Ubuntu 20.04

wget -qO - | sudo apt-key add - ;
echo 'deb focal main' > /etc/apt/sources.list.d/fleetssl.list ;
apt-get update && apt-get -y install letsencrypt-cpanel ;


If there are no problems, you should be able to run a successful self-test immediately afterwards:

le-cp self-test
[SELF-TEST] Can read config ............ SUCCESS.
[SELF-TEST] Can connect to daemon and check licence ............ SUCCESS.
[SELF-TEST] Can connect to Lets Encrypt ............ SUCCESS.
[SELF-TEST] Can talk to WHM API ............ SUCCESS.

Testing the installation

Now that the installation is complete, you should be able to login to any cPanel server on that server, and see the “Let’s Encryptâ„¢ SSL” icon on the home screen.

You should be able to immediately issue certificates, provided that the domain actually points to the server.
