How to Install Terraform Locally on Unix, Windows, and Mac

Terraform is an open-source infrastructure-as-code tool developed by HashiCorp. It allows you to define and provision data center infrastructure using a clear, declarative configuration language. Installing Terraform on your local machine lets you efficiently manage your infrastructure directly. This guide explains how to install Terraform on Unix (Linux), Windows, and macOS systems.

Prerequisites

• A stable internet connection
• Basic knowledge of command line operations
• Administrative or sudo privileges on your machine

Installation on Unix (Linux)

Step 1: Download Terraform

• Visit the Terraform releases page.
• Find the latest version suitable for your Linux distribution.
• Copy the download link for the 64-bit Linux zip archive.

Alternatively, use wget or curl in the terminal:

wget https://releases.hashicorp.com/terraform/<VERSION>/terraform_<VERSION>_linux_amd64.zip

Replace <VERSION> with the latest version number, e.g., 1.5.7.

Step 2: Unzip the Terraform binary

unzip terraform_<VERSION>_linux_amd64.zip

Step 3: Move Terraform binary to a directory in your PATH

sudo mv terraform /usr/local/bin/

Step 4: Verify the installation

terraform -v

You should see the installed Terraform version.

Installation on Windows

Step 1: Download Terraform

• Go to the Terraform downloads page.
• Download the Windows 64-bit zip archive.

Step 2: Extract the ZIP file

• Right-click on the downloaded ZIP file and select “Extract All”.
• Extract the terraform.exe file.

Step 3: Add Terraform to your system PATH

• Move the terraform.exe file to a folder, e.g., C:\Terraform.
• Add this folder to your system PATH:

• Open Control Panel > System and Security > System > Advanced system settings.
• Click Environment Variables.
• Under System variables, find and select Path > Edit.
• Click New, add C:\Terraform, and click OK to confirm.

Step 4: Verify installation

Open Command Prompt or PowerShell and run:

terraform -v

You should see the Terraform version printed.
