How to install Certbot on Raspberry Pi

Certbot is a free and open-source tool that automates the process of obtaining and renewing SSL/TLS certificates for your website. It simplifies the task of enabling HTTPS for your Raspberry Pi and ensures that your website stays secure. In this article, we will guide you through the process of installing Certbot on Raspberry Pi.

Prerequisites

Before installing Certbot, make sure you have the following:

• A Raspberry Pi with an active internet connection.
• A keyboard, mouse, and monitor to interact with the Raspberry Pi.
• An SD card with the latest version of Raspberry Pi OS installed.

Installing Certbot on Raspberry Pi

Step 1: Update the Raspberry Pi

To begin with, update your Raspberry Pi with the latest software packages. Open the Terminal on Raspberry Pi and run the following commands:

sudo apt update
sudo apt upgrade

Step 2: Install Certbot

To install Certbot on Raspberry Pi, run the following command in the Terminal:

sudo apt install certbot

The installation process may take a few minutes to complete, and it may prompt you for confirmation. Once completed, Certbot will be installed on your Raspberry Pi.

Step 3: Obtain SSL Certificate

To obtain an SSL certificate for your domain, run the following command in the Terminal:

sudo certbot certonly --standalone -d yourdomain.com

Replace “yourdomain.com” with your actual domain name. Certbot will then guide you through the process of obtaining and configuring the SSL certificate for your website.

Step 4: Automatic Certificate Renewal

Certbot provides a convenient way to automate the renewal of your SSL certificate. To set up automatic certificate renewal, run the following command in the Terminal:

sudo crontab -e

This command will open the crontab file in a text editor. Add the following line at the end of the file:

0 0 * * * certbot renew

Save the file and exit the editor. This will schedule Certbot to check for certificate renewal every day at midnight.

Step 5: Test SSL Configuration

To verify that the SSL certificate is installed correctly and working, you can visit your website using HTTPS. Open a web browser and navigate to https://yourdomain.com. If everything is set up correctly, you should see a secure connection with a padlock icon.
