by Muhammad in AWS Hosting, Compliance, Data Security, GDPR, How To on November 7, 2023

Securing an AWS Lightsail instance with HTTPS is a critical step after pointing the application to its domain. The process may differ slightly from that on an EC2 instance, but the simplicity of Bitnami’s bncert-tool streamlines the SSL installation.

Step 1: Connect Lightsail Terminal

Click on “Connect with SSH” button under Connect Tab on your lightsail instance details section to connect with terminal.

Step 2: Starting with bncert-tool

Begin by running the command:

					sudo /opt/bitnami/bncert-tool

If the tool is not present, proceed to install it before moving to the next step.

Installing bncert-tool

Execute the following commands to install bncert-tool:

					wget -O
sudo mkdir /opt/bitnami/bncert
sudo mv /opt/bitnami/bncert/
sudo chmod +x /opt/bitnami/bncert/
sudo ln -s /opt/bitnami/bncert/ /opt/bitnami/bncert-tool


Step 3: Domain Input

Input the domains requiring SSL certificates, including both www and non-www versions.

Step 4: Domain Redirection

Decide on the preferred redirection—typically from non-www to www—and confirm.

Steps 5: Completing the Setup

Enter the requested email address, agree to the terms and conditions, and let the tool finalize the SSL setup.

After these steps, the website should display a secure connection, indicated by a green padlock in the browser’s address bar.

By following this guide, users can efficiently secure their AWS Lightsail instances, ensuring enhanced security and credibility for their websites.
