Install a certificate on Plesk (9 and 10) (in server mode - shared IP)

You received your certificate by email with one or several intermediate certificates and a root certificate. Keep this email within reach.

1- Retrieve your certificate(s) on your server

In the delivery email you'll find several links. Click on them and download the associated files:

• A: your server certificate
• B: the certification chain

Keep the 2 pages open.

2- Set up Plesk

Login to the Plesk Control Panel as an administrator.

To manage your certificates on PLESK go to:
Tools & Utilities > SSL Certificates (in the Resources group).

Your SSL certificate will be displayed containing a CSR and a private key.
Select the certificate and add elements:

• the certificate (file A) in "Certificate"
  Send the certificate in text format
  Copy your certificate content (file A) that is accessible from the delivery e-mail.
  
  It should begin with:
  -----BEGIN CERTIFICATE-----
  
  And end with:
  -----END CERTIFICATE-----
  
  And paste it in "Certificate'
• Now, you need to install the certification chain (file B) in "CA Certificate".
  Send the certificate in text format
  Copy the certification chain content (file B) that is accessible from the delivery e-mail.
  
  It should begin with something like:
  subject=/C=US/ST=UT/L=Salt Lake City/O=The USERTRUST Network/CN=USERTrust Legacy Secure Server CA issuer=/C=US/O=Entrust.net/OU=www.entrust.net/CPS incorp. by ref. (limits liab.)/OU=(c) 1999 Entrust.net Limited/CN=Entrust.net Secure Server Certification Authority
  -----BEGIN CERTIFICATE-----
  
  And ends with:
  -----END CERTIFICATE-----
  
  And paste the whole file content in "CA Certificate".

Once the certificate installed (it appears in the list on the bottom of the page) you have to link the certificate to your IP address.



Go back to the "Tools & Utilities" page and click "IP Addresses".



Click the IP address and select the certificate in the dropdown list. Here you can change the certificate that is displayed by default.

3- Restart Plesk and run a test

Plesk normally take accounts your modifications directly so run a test on several browsers.

If it does not work, restart your Plesk server via the platform.

Case of a PLESK server using SNI (multiple certificates on a same server)

The SSL has to be configured in 2 different places:

• on the server for the NON-SNI part with the main certificate (as explained up here)



• regarding the domain, you'll have to:
  
  a) select power user mode
  
  b) click on "secure your web site", select the website and create the certificate in this section
  
  c) go back to "Websites & Domains" and click on the website name in the Domain column (website settings)
  
  d) select Enable SSL and the certificate. Regenrate the configuration and re-activate will be done in a matter of seconds.
