🔒 Plesk SSL installation

SSL certificates ensure a secure connection between your website and visitors via HTTPS. This guide explains how to create a CSR via cPanel, then order and configure the certificate until final installation.

🎬 Practical Video Guide – SSL Certificate Installation

This video provides a step-by-step practical demonstration of how to install and configure SSL Certificates.
You will see how to generate the CSR, validate the certificate, upload it to the server, and confirm that the website is secured (HTTPS) through a real example.

1️⃣ Generate a Certificate Signing Request (CSR)

The CSR (Certificate Signing Request) is required to obtain your SSL certificate from a Certificate Authority (CA).

Steps:

  1. Log in to your Plesk control panel (for example: https://yourdomain.com:8443

  2. Go to:
    Websites & Domains → [Select your domain]

  3. Click SSL/TLS Certificates.

  4. Click Add SSL/TLS Certificate.

  5. Fill in the CSR details:

    • Certificate name: e.g., domain-ssl-2025

    • Domain name: e.g., yourdomain.com

    • Organization name: Your company or website name.

    • Organization unit: Optional (e.g., IT Department)

    • City, State, Country: Your location info.

  6. Click Request.

  7. Plesk will generate your CSR and Private Key.
    Scroll down to find the CSR code — copy the entire block
    (from —–BEGIN CERTIFICATE REQUEST—– to —–END CERTIFICATE REQUEST—– ).

🗒️ Internal Note:
After generating the CSR, copy both the CSR and the Private Key and add them as a note or comment inside the related support or installation ticket.
This ensures any colleague continuing the process can access the required files and complete the SSL installation smoothly.

2️⃣ Create an SSL Certificate on the Services Page

  1. After payment, go to the service page in your WHMCS.

  2. But before creating, ensure the creation of the email admin@example.com 📧

    1. If the domain is hosted with us, pointing to our nameservers, and MX records point to us, we will follow up with creating the email and receiving the certificate directly ✅

    2. If the email is not working or MX points elsewhere ⚠️, the client must ensure the email exists and can receive messages, as the certificate will be sent there.

    3. Press Creat for Module

3️⃣ Configuring the Certificate in Client Area 

  1. Log in to your Client Area.

  2. Go to the service page for the certificate.

  3. Choose your Webserver type:

    • Windows service: select Plesk

  4. Paste the CSR Code obtained from the technical team ✂️.

  5. Scroll down and click Click to Continue.

  6. Select the domain that will receive the certificate, and set the email to admin@example.com.

3️⃣ Upload the SSL Certificate

Once your CA issues the certificate, you’ll receive one or more files:

  • yourdomain.crt → Your main certificate

  • ca-bundle.crt or intermediate.crt → Intermediate chain files

Steps:

  1. In Plesk, go to:
    Websites & Domains → SSL/TLS Certificates

  2. Click the same certificate name you created earlier.

  3. Under Upload the certificate files, upload:

    • Your main certificate file (.crt)

    • The CA bundle file (.ca-bundle)

  4. Click Upload Certificate.

4️⃣ Install the Certificate on Your Website

Now you’ll need to apply the uploaded certificate to your domain.

Steps:

  1. Go to:
    Websites & Domains

  2. Click Hosting Settings (or Hosting & DNS → Hosting Settings).

  3. Under Security, make sure:

    • ✅ SSL/TLS support is checked.

    • From the Certificate dropdown, select your uploaded certificate.

  4. Click OK or Apply.
