How to install Let’s Encrypt
Login to the Server
cd /etc/yum.repos.d/ && wget https://letsencrypt-for-cpanel.com/static/letsencrypt.repo

yum -y install letsencrypt-cpanel
The installation process usually takes about a minute. If all goes well and the installation was successful, a test should run automatically.
Once you’re logged into cPanel, you should see a Let’s Encrypt for cPanel button under Security. Click on it to access your active domains list to install a certificate.
