Question

How I get SSL for my Subdomain and show me other SSL Certificates

Posted November 7, 2021 93 views

Hello together,

I have the following conditions:

  • Bought Domain at Namecheap
  • Did DNS with AWS
  • At AWS is a CNAME to my Domain here at DO (it is a tracking Server/Domain)
  • I use a Subdomain at my tracking Tool. The Tracking Tool is hosted on DO. I need a SSL certificate for this Subdomain. So I must install the SSL certificate on my DO Server.

I know that the IT expert at my company has already used this procedure for other subdomains. (He’s no longer with the company, so I can’t ask him)

How do I get to the console of my DO server and with which command can I check whether there are already more SSL certificates for other subdomains?
In AWS it is e.g. sudo certbot certificates (I use let’s encrypt there)

Thanks a lot

Hello,

You can also use Let’s Encrypt together with certbot on your DigitalOcean server.

Here is a link to a step by step article on how to install certbot and use it:

https://www.digitalocean.com/community/tutorials/how-to-secure-apache-with-let-s-encrypt-on-ubuntu-20-04

Let me know if you have any questions.

Bobby

Let's Encrypt is a Certificate Authority (CA) that facilitates obtaining and installing free TLS/SSL certificates, thereby enabling encrypted HTTPS on web servers. Currently, the entire process of obtaining and installing a certificate is fully automated on both Apache and Nginx with the use of Certbot. In this guide, we'll use Certbot to obtain a free SSL certificate for Apache on Ubuntu 20.04, and make sure this certificate is set up to renew automatically.
  • Hi Bobby,

    thank you so much. I will try the tutorial. Can you please tell me briefly what I can enter in the console in order to first read out which SSL certificates are currently installed on my Ubuntu server.

    I can see from the tutorial from you that Apache is needed. If I read my server with https://www.sslshopper.com/ssl-checker.html, it says that I am using Nginx. Can I check whether Apache is also installed on the server?

    So I first have to come to the server console, then I would like to read for what SSL certificates have been installed so far and whether Apache is installed?

    I hope you can help me with this too. Thanks in advance.

  • Now I have the solution for all. Thank you.
