How to add a domain in Certbot on Debian?

When adding a new domain or subdomain to Certbot on Debian, we are essentially asking the Let’s Encrypt certificate authority for an SSL/TLS certificate for that domain or subdomain. With the help of this certificate, the website or service can connect securely to users via HTTPS. A tool called Certbot makes getting and managing these certifications easier.

Steps to add the domain in Certbot on Debian

Install Certbot:

We must install Certbot on the Debian system if we haven’t previously. Ensure the setup is done with proper plugin for the web server (such as Apache or Nginx).

Select a Plugin:

Certbot supports a number of plugins that automate setting up the webserver to use the certificates we’ve got. Select the right plugin based on the web server we’re using.

Launch Certbot:

For Apache, run the following code:

For NGINX, run the following code:

Follow the Suggestions:

We will be guided through the process of getting the certificate after running the Certbot code. It may be necessary for us to accept the terms of service, give the email address for notifications, and perhaps decide whether to switch HTTP traffic to HTTPS.

Verification and Configuration:

To make sure we have control over the domain for which we are obtaining a certificate, Certbot will automatically verify the domain ownership. So, the web server will then start using the new certificate after that.

Testing and Confirmation:

Once the certificate has been installed, test the website by using HTTPS to access it. Verify that the SSL/TLS connection is working properly and that the certificate is accepted as being legitimate.

Conclusion

The user-friendly interface of Certbot makes adding a new domain or subdomain a fairly simple process. We can protect the new domain with a legitimate SSL/TLS certificate from Let’s Encrypt by following the instructions above.
