SSL certificates are important for keeping websites secure. They encrypt data sent between your website and its visitors. Sometimes, these certificates expire and need to be renewed. Certbot is a free tool that makes renewing SSL certificates easy. This guide will show you how to renew an SSL certificate for a specific domain (e.g., “yourdomain.com” and “www.yourdomain.com”) using Certbot in simple steps.

What You Need

Before you start, make sure you have:

  • Access to your server (you need to be able to log in).
  • Certbot installed on your server.
  • Your website must already have an SSL certificate set up.

Step-by-Step Guide to Renew Your Specific Domain’s SSL

Step 1: Log In to Your Server

First, you need to log in to your server. You can use SSH (Secure Shell) to do this. If you are using a terminal or command prompt, type:

ssh your-username@your-server-ip

Replace your-username with your actual username and your-server-ip with your server’s IP address. Press Enter and type your password if prompted.

Step 2: Check Certbot Installation

Make sure Certbot is installed on your server. Type the following command:

certbot --version

If Certbot is installed, you will see the version number. If it is not installed, you need to install it. Here is a simple way to install Certbot on Ubuntu:

sudo apt update
sudo apt install certbot

Step 3: Renew the SSL Certificate for a Specific Domain

To renew the SSL certificate for a specific domain, use the certonly command with Certbot. This command will request a new certificate for the specified domain(s):

sudo certbot certonly --standalone -d yourdomain.com -d www.yourdomain.com

Replace yourdomain.com and www.yourdomain.com with your actual domain names. Certbot will renew the SSL certificate for these domains.

Step 4: Restart Your Web Server

After renewing the SSL certificate, you need to restart your web server to apply the changes. The command depends on the web server you are using. Here are commands for common web servers:

Apache:

sudo systemctl restart apache2

Nginx:

sudo systemctl restart nginx

Step 5: Verify the Renewal

To make sure your SSL certificate has been renewed, you can check your website using a web browser. Visit your website and click on the padlock icon in the address bar. You should see information about your new SSL certificate, including the new expiration date.

You can also visit our online SSL Checker tool to verify the status of the certificate.

Conclusion

Renewing an SSL certificate for a specific domain using Certbot is a straightforward process that enhances your website’s security. By following these simple steps, you can ensure that your SSL certificates are up-to-date, protecting your site and its visitors. Regularly checking your certificates and setting up automatic renewals can save time and prevent any disruptions. With Certbot, maintaining secure connections for your website is easy and efficient.
