Installing your Plesk Server SSL Certificate

Download the Primary, Intermediate, and Root certificate files from your the trusted CA site you used.

Select ‘Domains’ from the left hand menu.

Click on the domain name that the certificate is for.

Click on the ‘Certificates’ menu item.

You will have the option to either “Upload certificate files” or “Upload certificate as text.” Either way will work fine for your purposes.

To upload the files – just click “Browse” next to the “Certificate” box and navigate to the location of the your_domain_name.crt file you received from the trusted CA site.

Then, next to “CA certificate”, click and browse to the Intermediate.crt file. Select it, then select ‘Send File’. This will install the certificates against their corresponding Private Key.

To Upload certificates as text – Open your_domain_name.crt and YourCA.crt as text files and copy the entire body of those files into the boxes provided under “Upload certificate as text”.

The your_domain_name.crt should be uploaded as the “Certificate”, and the Intermediate.crt as the “CA Certificate”.

Next, click on Server > IP Addresses, then click on the IP Address for your Web site.

Change the certificate for your site to use the new SSL Certificate you have just installed.

Click the ‘Server’ item from the left hand menu.

Click on the ‘Service Management’ menu item.

Stop and Start the WEB Server (Apache) to activate the certificate.

NOTE: Restarting Apache will NOT work. You must stop the service, then start it again to complete the installation.
