How to Install an SSL Certificate in DirectAdmin Panel

Securing your website with an SSL certificate is crucial in today’s digital landscape. An SSL certificate encrypts data transmitted between your website and its visitors, ensuring security and trust. DirectAdmin, a popular web hosting control panel, provides a straightforward way to install SSL certificates. This detailed guide will walk you through the process of installing an SSL certificate in the DirectAdmin panel.

What you’ll need

Before you start the installation process, ensure you have the following:

  • Access to DirectAdmin Panel: You need administrative access to your DirectAdmin control panel.
  • SSL Certificate Files: You should have your SSL certificate files, including the certificate itself, the CA bundle (if provided), and the private key.

Steps to install an SSL certificate in DirectAdmin Panel

Step 1: Generate a Certificate Signing Request (CSR)

A Certificate Signing Request (CSR) is required to obtain an SSL certificate from a Certificate Authority (CA). Here’s how to generate a CSR in DirectAdmin:

  1. Log in to DirectAdmin: 
    • Access your DirectAdmin control panel using your admin credentials.
  2. Navigate to SSL Certificates:
    • From the main dashboard, click on “SSL Certificates” under the “Advanced Features” section.
  3. Generate CSR:
  • Click on the “Create A Certificate Request” tab.
  • Fill in the required details:
    • Common Name (CN): Your domain name (e.g.,
    • Organization: Your company name.
    • Organizational Unit: Your department (e.g., IT, Marketing).
    • City, State, and Country: Your business location.
  • Click on “Save” to generate the CSR.
  • Copy the generated CSR as you will need to provide it to the Certificate Authority (CA) when purchasing the SSL certificate.

Step 2: Purchase and Obtain Your SSL Certificate

After generating the CSR, you need to purchase an SSL certificate from a trusted Certificate Authority (CA) such as Comodo, DigiCert, or Let’s Encrypt. Provide the CSR to the CA during the purchase process. The CA will then validate your details and issue the SSL certificate, which you will receive via email.

Step 3: Install the SSL Certificate in DirectAdmin

Once you have obtained the SSL certificate files, follow these steps to install them in DirectAdmin:

  1. Log in to DirectAdmin: Access your DirectAdmin control panel.
  2. Navigate to SSL Certificates:
    • From the main dashboard, click on “SSL Certificates” under the “Advanced Features” section.
  3. Paste Certificate and Key:
    • Select the “Paste a pre-generated certificate and key” option.
    • In the “Certificate” field, paste the SSL certificate you received from the CA.
    • In the “Key” field, paste the private key you generated with the CSR.
  4. Add CA Bundle:
    • If your CA provided a CA bundle (intermediate certificates), find the “CA Root Certificate” or “Certificate Authority Bundle” section.
    • Paste the CA bundle in this field.
  5. Save the Certificate:
    • Click on “Save” to install the SSL certificate.

Step 4: Enable SSL for Your Domain

After installing the SSL certificate, you need to enable SSL for your domain:

  1. Navigate to Domain Setup:
    • From the main dashboard, click on “Domain Setup” under the “Your Account” section.
  2. Select Your Domain:
    • Click on the domain for which you installed the SSL certificate.
  3. Enable SSL:
    • Check the box next to “Secure SSL” to enable SSL for your domain.
    • Check the box next to “Use a symbolic link from private_html to public_html” if you want to use the same document root for both secure and non-secure pages.
    • Click on “Save” to apply the changes.

Step 5: Test Your SSL Installation

It’s important to verify that your SSL certificate is correctly installed and functioning. Here’s how:

  1. Visit Your Website:
    • Open your web browser and navigate to
  2. Check the Certificate Details:
    • Click on the padlock icon in the address bar to view the SSL certificate details.
    • Ensure that the certificate is valid and issued by the CA you purchased it from.
  3. Use Online Tools:
    • Use online SSL verification tools such as SSL Labs’ SSL Test to analyze your SSL installation and configuration.

Troubleshooting Common Issues

If you encounter issues during the SSL certificate installation, here are some common problems and solutions:

  1. Incorrect Private Key:
    • Ensure that the private key you are using matches the CSR generated earlier. If they don’t match, the certificate won’t work.
  2. Missing CA Bundle:
    • If the CA bundle is not included, your certificate may not be trusted by browsers. Ensure you paste the CA bundle in the appropriate section.
  3. DNS Propagation:
    • After making changes, DNS propagation might take some time. Wait a few minutes and then check again.
  4. Mixed Content Warnings:
    • Ensure that all resources (images, scripts, stylesheets) on your website are loaded via HTTPS to avoid mixed content warnings.


Installing an SSL certificate in DirectAdmin is a critical step to secure your website and protect your users’ data. By following this detailed guide, you can successfully generate a CSR, obtain an SSL certificate, and install it in DirectAdmin. Regularly update and renew your SSL certificates to maintain security and trust. With your SSL certificate properly installed, your website will be secure, and your visitors will have confidence in the safety of their interactions with your site.


Q1. What is an SSL certificate and why do I need it for my website?

transferred between a user’s web browser and your website, ensuring secure communication. This encryption protects sensitive information such as login credentials, personal data, and payment details from being intercepted by malicious actors. Having an SSL certificate not only enhances your site’s security but also builds trust with your visitors, as evidenced by the padlock icon and “https://” in the address bar. Additionally, SSL is a crucial factor in search engine optimization (SEO) since search engines like Google prioritize secure sites in their rankings. Therefore, installing an SSL certificate is essential for both protecting your users and improving your website’s credibility and visibility online.

Q2. How do I generate a Certificate Signing Request (CSR) in DirectAdmin?

Generating a Certificate Signing Request (CSR) in DirectAdmin is a straightforward process. First, log in to your DirectAdmin control panel and navigate to the “SSL Certificates” section under “Advanced Features.” Click on the “Create A Certificate Request” tab and fill in the required fields, including your domain name, organization name, and location details. Once you’ve entered all the necessary information, click “Save” to generate the CSR. This CSR contains your public key and the information needed by a Certificate Authority (CA) to create your SSL certificate. Copy the generated CSR as you will need to provide it to the CA when purchasing your SSL certificate.

Q3. What are the common issues faced during SSL certificate installation in DirectAdmin?

During the installation of an SSL certificate in DirectAdmin, several common issues can arise. One frequent problem is using an incorrect private key that does not match the CSR generated earlier, which will cause the certificate to fail. Another issue is the absence of a CA bundle or intermediate certificates, which can result in browsers not trusting the SSL certificate. DNS propagation delays can also be a factor; changes to DNS settings might take some time to propagate, leading to temporary verification failures. Additionally, mixed content warnings can occur if your website loads some resources over HTTP instead of HTTPS, which browsers will flag as insecure. Ensuring all these elements are correctly configured will help avoid these issues.

Q4. How can I verify if my SSL certificate is installed correctly on my website?

Verifying the correct installation of your SSL certificate involves a few steps. First, visit your website using “https://” and check if the padlock icon appears in the browser’s address bar. Clicking on this padlock will display details about your SSL certificate, including its validity and issuing Certificate Authority. For a more comprehensive check, you can use online tools such as SSL Labs’ SSL Test, which provides a detailed analysis of your SSL configuration and highlights any potential issues. These tools will verify the proper installation of your certificate, check for the presence of intermediate certificates, and ensure that all parts of your website are served securely over HTTPS.
