This article will explain how to install an SSL certificate for your domain using Plesk.

Note: You must first obtain an SSL certificate for your website before proceeding with the instructions.

Let us follow the steps:

1. Go to your Plesk account and log in. 

2. Select ‘Domains’ from the left-hand menu. And select your Domain.

3. Select the ‘SSL/TLS Certificates’ option from the drop-down menu.

4. Click on ‘Advanced Settings’ option.

5. On the SSL/TLS Certificates tab, there is an option to upload a (*.crt) SSL Certificate file. Select the option – ‘Add SSL/TLS Certificate’ if you want to upload an SSL certificate and a private key pair established on a different server, or if you want to generate a self-signed certificate. 

6. You will be redirected to a new screen. You can create a request for a certificate in the upper section of this screen. You must fill out the essential information and then click on the relevant option – ‘Request’ or ‘Self-Signed’ – to purchase a certificate from your web hosting company or to generate a self-signed certificate using Plesk.

7. You can upload certificates and private keys in the ‘Upload the certificate files’ section. To upload a file, pick it by clicking on the ‘Choose File’ button. Click ‘Upload Certificate’ when the upload is finished.

8. Your SSL certificate can also be uploaded as text.

9. Go to the ‘Upload certificate as text’ section if your SSL certificate is stored as a text file. You can paste the certificate and private key text into the appropriate fields here. Click on ‘Upload Certificate’ after you’ve entered the txt files. 

10. Return to ‘Domains’ and select the option ‘Hosting Settings’ once your certificate has been created. 

11. On the settings page, go to the ‘Security’ section and check the box next to ‘SSL/TLS support’. Below this choice is a certificate drop-down box; select your certificate from this drop-down box and click ‘Ok.’ 

In this way, using the Plesk control panel you can now install your SSL certificate.
