Firstly when your issuance email arrives it will contain your web server certificate. Copy your web server certificate into a text editor such as notepad including the header and footer. You should then have a text file that looks like:
-----BEGIN CERTIFICATE-----
[encoded data]
-----END CERTIFICATE-----
Make sure you have 5 dashes to either side of the BEGIN CERTIFICATE and END CERTIFICATE and that no white space, extra line breaks or additional characters have been inadvertently added.
1. Open the Site Management console to manage your web site
2. Select the CERTIFICATE box containing the self-signed certificate and delete this content.
3. Copy the contents on the certificate file previously created from the -----BEGIN CERTIFICATE----- up to and including the -----END CERTIFICATE----- and PASTE this into the CERTIFICATE box
4. Select “Use manually entered certificate” at the bottom and SAVE CHANGES. Be careful not to click SAVE CHANGES more than once!
5. Restart or Reboot the Apache server
6. Be sure to backup your "Certificate" and its matching "private key"
For the admin server:
/home/sites/home/certs/certificate
/home/sites/home/certs/keyFor a virtual server with associated site number:
/home/sites/site##/certs/certificate
/home/sites/site##/certs/keyTest your certificate by using a browser to connect to your server. Use the https protocol directive (e.g. https://your server/) to indicate you wish to use secure HTTP. The padlock icon on your browser will be displayed in the locked position if your certificates are installed correctly and the server is properly configured for SSL.
