Installing an SSL Certificate in Plesk (Linux or Windows Servers)

In this article, we'll show you how to secure a website managed in Plesk with an SSL certificate.

To give a brief overview of how to set up an SSL certificate in Plesk, you need to add the SSL certificate to the domain and then connect the website to your certificate.


Adding the SSL Certificate

  • Click Domains in the navigation bar on the left.

  • Click the domain you want.

  • In the Dashboard tab, click SSL/TLS Certificates.

The SSL/TLS Certificate for [domain name] page is displayed.

  • Scroll down and click the Manage button below Download or Remove Existing Certificates.

  • Click Add SSL/TLS Certificate.

The Add SSL/TLS Certificate page is displayed.

  • Give the certificate any name you want.

  • Go to the Upload the certificate files section and select the Private Key, Certificate, and the CA Certificate (in this case being the Intermediate certificate) files on your computer.

  • Click Upload Certificate.

Choosing the SSL Certificate as the Default Among Multiple Certificates

If you have uploaded multiple SSL certificates, you must select the desired SSL certificate in the list of certificates in the server pool as the default. To do this, proceed as follows:

  • In the navigation bar on the left, click Tools & Settings.

  • Click SSL/TLS Certificates in the Security section.

  • In the List of certificates in server pool section, select the desired SSL certificate.

  • Click Use as default.

Connecting Your Website with the SSL Certificate

After you add the certificate, you can enable SSL/TLS support and connect the certificate to the website.

  • In the menu on the left, select Domains and click on the desired domain.

  • In the Hosting & DNS tab, select Hosting Settings.

  • Go to the Security section and select the following settings:

    Enable SSL/TLS support.
    Enable the Permanent SEO-safe 301 redirect from HTTP to HTTPS option.

  • In the Certificate section, select your SSL certificate.

  • Click OK.

Your website is now accessible by using https:// instead of the unsecured http://.

Protecting Webmail/Email

  • You will be returned to the domain you selected previously. In the Dashboard tab, select SSL/TLS Certificates.

  • Click Advanced Settings.

  • Select the desired certificate.

  • To use the SSL certificate to protect webmail, click Secure Webmail.

  • To use the SSL certificate to protect emails, repeat steps 1-3 in this section.

  • Finally, click Secure Mail.

Your domain, webmail, and emails have now been successfully secured by your SSL certificate.
