In order to install an SSL certificate on cPanel, you need to have generated a CSR and requested an SSL certificate. Please read the manual Generate a CSR in cPanel for more information.
The SSL certificate will be sent to you by email after the request has been processed, but can also be downloaded through your account on the Networking4all website.
The installation of an SSL certificate in cPanel is done in the cPanel control panel.
Select ‘SSL/TLS Manager’ in the control panel. Go to ‘generate, view, upload or delete SSL certificates’. Open the SSL certificate file in a text editor, copy the contents and paste them into the field ‘upload a new certificate’. Click ‘upload’.
Click ‘go back’. You will automatically be sent to a page where you can install the CA bundle. The fields for the certificate and key will have been filled with the certificate. Copy the entire contents of the CA bundle file and paste it in the field ‘CA Bundle’. Select ‘install certificate’.
Your certificate has been installed. Restart your Apache server to load the new configuration and complete the installation process.
