In Renew a Let’s Encrypt SSL/TLS Certificate on an AWS EC2 Instance I went over the steps to renew your Let’s Encrypt SSL/TLS certificate, which will expire every 90 days. It’s good to know how to renew the certificate yourself, but once you do you can write a bash script to automate that renewal process. Here’s a basic overview of how that works:

1. Create a bash script that executes the same renew commands used in Renew a Let’s Encrypt SSL/TLS Certificate on an AWS EC2 Instance.
2. Upload that bash script to your EC2 instance.
3. Create a cron job. Cron is a function in Linux that allows you to schedule automated tasks, allowing you to run your bash script at a specific time and a specific interval. In this example, we will execute the bash script at midnight on the first day of every month.

Unfortunately, when I tried this, it didn’t actually work for me. So the steps below provide a description of the symptom, along with my workaround.

In Install a Let’s Encrypt SSL/TLS Certificate on an AWS EC2 Instance, we learned how to install the Lego client to create and manage TLS/SSL certificates provided by Let’s Encrypt. The certificates issued by Let’s Encrypt expire every 90 days, so you will need to renew them before they expire to maintain your website’s HTTPS connection. Let’s Encrypt will send you an email to notify you that your certificate is expiring soon.

This post shows you to use your EC2 instance’s command-line interface to download and install Lego, a Let’s Encrypt client written in the Go programming language. Lego will allow you to create and manage SSL/TLS certificates from the Let’s Encrypt Certificate Authority.

In this example I am installing a Let’s Encrypt certificate on a LAMP-stack virtual server (in this case an EC2 instance from Amazon Web Services) over Secure Shell (SSH). After that, I’ll show you how to download a copy of your certificates and account information using an FTP client. I am using the macOS Terminal, which is Unix-based, but the Linux commands will be the same regardless of what command-line interface you are using. I am also using the Cyberduck FTP client, but any FTP client should work.
