Step-by-Step ⚠️ Guide to Installing SSL Certificates

By Yasmin Apr29,2024

When starting the process of installing an SSL certificate, the first step is to obtain the certificate itself. This involves choosing a reputable Certificate Authority (CA) that will issue the SSL certificate for your website. It’s essential to research and compare CAs based on their reputation, security standards, and pricing. Some popular options include Comodo, Symantec, VeriSign, GoDaddy, and the free provider Let’s Encrypt.

After selecting the CA, the next step is to choose the right certificate type for your website. There are three main types to consider:

Domain Validation (DV): This type only verifies domain ownership.

Organization Validation (OV): Verifies domain ownership and organization information.

Extended Validation (EV): The most comprehensive option, verifying domain ownership, organization details, and physical address.

Lastly, you’ll need to generate a Certificate Signing Request (CSR). This involves providing the CA with your domain name, organization details, location, and email address. You can generate the CSR using your web hosting control panel or a dedicated CSR generation tool.

Installing the SSL Certificate on Your Server

Installing the SSL Certificate on Your Server


For Apache servers, the installation process involves obtaining the SSL certificate and intermediate certificates from the CA. These certificates need to be placed in the appropriate location on your server. You’ll then need to edit the Apache configuration file and add directives such as:

SSLCertificateFile: Path to the server certificate file

SSLCertificateKeyFile: Path to the server key file

SSLCertificateChainFile: Path to the certificate chain fileFinally, remember to restart the Apache service for the changes to take effect.


If you’re using Nginx as your web server, the steps are similar. Obtain the SSL certificate and intermediate certificates, place them in the appropriate location, and edit the Nginx configuration file with directives including:

ssl_certificate: Path to the server certificate file

ssl_certificate_key: Path to the server key file

ssl_trusted_certificate: Path to the certificate chain fileDon’t forget to restart the Nginx service after making these changes. Dive deeper into Troubleshooting Common SSL Certificate Problems

Configuring SSL Settings

Configuring SSL Settings

Now that the SSL certificate is installed, it’s important to configure SSL settings for your website.

Redirecting to HTTPS

Consider implementing an HTTP redirect or using HTTP Strict Transport Security (HSTS) headers to ensure all traffic is redirected to HTTPS for a more secure browsing experience.

Supporting Multiple Domains (SANs)

To support multiple domains on a single certificate, you can either obtain a wildcard certificate or utilize Server Name Indication (SNI) to configure your server to handle multiple domains.

Configuring HSTS

Setting the Strict-Transport-Security header will instruct browsers to only connect to your site over HTTPS, adding an extra layer of security.

Enabling HTTP/2

Check if your server supports HTTP/2 and enable it if possible to benefit from improved performance and security features.

Verifying the Installation

After configuring your SSL settings, it’s crucial to verify the SSL certificate installation to ensure everything is set up correctly.

Using an SSL Checker

Utilize online SSL checker tools like SSL Labs or Qualys SSL Labs to test your certificate installation and identify any potential issues.

Browsing the Website

Manually check your website by navigating to it in a web browser. Ensure the URL bar displays a padlock icon to indicate a secure connection over HTTPS. Find more on Understanding SSL: A Beginner’s Guide

Troubleshooting Common Issues

You may encounter common issues that need troubleshooting.

Incorrect Certificate Installation

If you face issues, double-check the certificate file paths and permissions. Ensure the certificate chain is complete and installed correctly in the designated order.

Mixed Content

Avoid mixed content errors by ensuring that all resources on your website, including images, scripts, and stylesheets, are served securely over HTTPS.

Browser Errors

Address any browser compatibility issues or expired certificates by verifying your SSL configuration. Clearing your browser cache and cookies can also resolve certain problems.

Certificate Authority Issues

In case the certificate is not correctly installed or validated, don’t hesitate to contact the Certificate Authority for assistance to rectify the issue promptly.

By following this comprehensive step-by-step guide, you can successfully install SSL certificates on your server and enhance the security of your website for your visitors.
