Installation of an SSL Certificate on Parallels Plesk

Article Rating: 2 / 5 Votes: 32

Installing a Certificate on Parallels Plesk®

To install your certificate, you will need to log in to your Plesk® account. The screenshots are from the latest Plesk release (v9), but the instructions apply to versions 7-9.

You will have received your certificate from us, a file typically named 'your_domain_com.crt' as well as the intermediate certificates UTNAddTrustServer_CA.crt and NetworkSolutions_CA.crt.  The root certificate AddTrustExternalCARoot.crt may also be provided.

  1. Log in to Plesk. Click on 'Domains' from the left-hand menu, then click the domain you wish to request the certificate for. Click the 'SSL Certificates' icon.


  1. Click the name of the certificate in the list. 
  2. Scroll down until you see two boxes for uploading text: 'Certificate' and 'CA certificate'. Open the certificate (a file typically named 'your_domain_com.crt') in a text-editor and copy and paste the whole contents into the 'Certificate' box.

    Now you must create the 'CA certificate' to be pasted into the second box. Firstly, paste in the contents of the root certificate (AddTrustExternalCARoot.crt). Then paste the contents of each intermediate certificate you have been sent, one after another (UTNAddTrustServer_CA.crt and NetworkSolutions_CA.crt).


  1. Click the 'Send Text' button. This will upload and install the certificate. Should you receive an error along the lines of 'The CA certificate does not sign the certificate', then please re-check Step 3, where you paste all the certificate files together.
