How Do I Renew My Web Server Certificate?


Angela Bailey

Renewing your web server certificate is an essential task to ensure the security and validity of your website. A valid certificate is necessary to establish a secure connection between your web server and your visitors’ browsers. In this tutorial, we will guide you through the steps to renew your web server certificate.

Step 1: Verify Certificate Expiration

Before proceeding with the renewal process, it’s important to check the expiration date of your current web server certificate. This information can be found in the certificate details or by contacting your certificate provider.

Step 2: Generate a Certificate Signing Request (CSR)

To renew your web server certificate, you’ll need to generate a new Certificate Signing Request (CSR). The CSR contains information about your website and is used by the certificate authority to issue a new certificate.

  • Access Your Web Server: Log in to your web server using SSH or any other remote access method.
  • Generate a New CSR: Use a tool like OpenSSL or an online CSR generator to create a new CSR file. Make sure to include accurate information such as the Common Name (CN), Organization (O), and Organizational Unit (OU).
  • Save the CSR: Once you have generated the CSR, save it as a text file. You will need this file in the next step.

Step 3: Submit the CSR for Renewal

Now that you have generated a new CSR, it’s time to submit it for renewal. Follow these steps:

  • Contact Your Certificate Provider: Get in touch with your certificate provider or visit their website to initiate the renewal process.
  • Upload the CSR: During the renewal process, you will be prompted to upload your CSR file. Locate the file you saved in Step 2 and provide it to the certificate provider.
  • Verify Ownership: Depending on your certificate provider, you may need to verify ownership of the domain.

    This can be done by adding a specific DNS record or uploading a verification file to your website’s root directory.

  • Complete Payment: Renewal fees vary depending on the certificate provider and the type of certificate. Complete the payment process as required.

Step 4: Install the Renewed Certificate

Once your renewal request is approved, you will receive the renewed web server certificate from your certificate provider. Now, let’s install it:

  • Access Your Web Server: Log in to your web server using SSH or any other remote access method.
  • Locate Existing Certificate Files: Find the directory where your current certificate files are stored. This is typically in a folder like “/etc/ssl” or “/etc/nginx/ssl”.
  • Backup Existing Certificates: Before replacing any files, make sure to create a backup of your existing certificates for safety.
  • Replace with New Certificate Files: Copy and replace the old certificate files with the new ones provided by your certificate authority.
  • Restart Your Web Server: Restart your web server to apply the changes and load the renewed certificate.
  • Verify Certificate Installation: Visit your website using HTTPS and check if the renewed certificate is correctly installed. You can use online SSL checker tools to validate the installation.


Renewing your web server certificate is a crucial step in maintaining a secure and trusted website. By following the steps outlined in this tutorial, you can ensure that your website remains protected and encrypted for your visitors.
