This guide walks you through installing an SSL/TLS certificate in Plesk 10. If you operate multiple servers or devices, you'll need to install the certificate on each one that requires secure connections. Before proceeding, ensure you have generated your certificate and completed the validation process.

What You'll Need

  • Your Server Certificate: The certificate provided by the Certificate Authority (CA) for your domain. You should have received it via email or can download it from your Account Dashboard.
  • Your Intermediate Certificates: These files (also called CA Bundle) enable devices connecting to your server to identify the issuing CA. If your certificate came in a ZIP folder, it should contain these files.
  • Your Private Key: This file should be on your server or in your possession if you generated your Certificate Signing Request (CSR). On some platforms like Microsoft IIS, the private key may not be immediately visible, but the server retains it.

How to Install the Certificate

  1. Step 1: Log in to Plesk

    Log in to Parallels Plesk Panel.

  2. Step 2: Navigate to Websites & Domains

    Choose the Websites & Domains tab from the top navigation menu.

  3. Step 3: Access SSL Certificate Settings

    Click on the SSL Certificate link.

  4. Step 4: Select Your Domain

    Click Manage next to the domain for which the certificate is intended.

  5. Step 5: Add SSL Certificate

    Click on Add SSL Certificate.

  6. Step 6: Upload Certificate Files

    Choose one of the following upload methods:

    Option 1: Upload Certificate Files
    Browse for your previously saved Private Key, Certificate (Your Server Certificate), and CA Certificate (Intermediate Certificates).

    Option 2: Upload Certificate as Text
    Copy your previously saved Private Key, Certificate, and CA Certificate from a text editor like Notepad and paste them into the blank text boxes.

    Important notes:

    • If you created the CSR and private key outside Plesk without saving the files, you may encounter issues. Consider re-issuing the SSL certificate with a newly generated key pair.
    • If you received the certificate in a ZIP file, extract it and open your server certificate in a text editor to ensure you copy all text including -----BEGIN CERTIFICATE----- and -----END CERTIFICATE-----.
    • If you don't have the intermediate certificates, download the relevant CA Bundle for your certificate.

  7. Step 7: Submit the Certificate

    Depending on the upload option selected, click either Send Files or Send Text.

  8. Step 8: Configure Hosting Settings

    Navigate back to the Websites & Domains tab, select your Domain Name, and click on Hosting Settings.

  9. Step 9: Enable SSL Support

    Check SSL Support and choose your newly uploaded Certificate Name from the Certificate dropdown menu.

  10. Step 10: Save Settings

    Click OK to confirm and save your SSL certificate settings.

Verify Installation

Visit your website at https://yourdomain.tld and check the certificate/site information to ensure HTTPS/SSL is functioning correctly. You may need to restart your server for the changes to take effect.
