How to Install Terraform on Linux

There are two methods to install Terraform on Linux. The primary method is using the Terraform zip that contains the executable you can unpack anywhere on your system. The other method is using the HashiCorp repository for your Linux distribution.

Install Terraform on Linux Using Zip Archive

Follow the steps below to install Terraform on a Linux system using the downloaded zip file. The instructions are the same for all Linux distributions.

1. Browse to the Download Terraform page.

2. Select the Linux tab under the Operating System heading. The latest version is preselected.

3. Scroll down and right-click the Download button for your system’s architecture. In our case, it is AMD64.

4. Use the wget tool to download the file:

wget https://releases.hashicorp.com/terraform/1.3.5/terraform_1.3.5_linux_amd64.zip
wget tool downloads the terraform file on Linux

5. Find a user directory in &PATH to put the Terraform binary in it:

echo $PATH
echo $PATH output Linux

We will use /usr/local/bin.

6. Unzip the file to the directory you chose. Use the full file name with the extension when extracting the archive. Make sure to use the correct name for your architecture and the version you downloaded. For example, for version 1.3.5, enter:

sudo unzip terraform_1.3.5_linux_amd64.zip -d /usr/local/bin
Extracting the Terraform archive on Linux

The output shows the path where the extracted Terraform file is located.

To verify if the Terraform directory is in the selected location, use the list command. For example:

ls -l /usr/local/bin

7. Confirm the installation is successful by running a terraform command. For example, check the version with:

terraform -version

The output shows the Terraform version you installed.

Install Terraform on Linux Using Package Repository

Follow the steps for your Linux distribution to install Terraform from the official HashiCorp repository. The repository contains other HashiCorp packages that are not related to Terraform.

Install Terraform on CentOS/RHEL

To install Terraform from the HashiCorp repository on a CentOS system:

1. Install the yum-utils tools.

sudo yum install -y yum-utils

The output shows that Terraform is installed. You can double-check by running the terraform -version command to see the installed Terraform version.

Install Terraform on Ubuntu/Debian

To install Terraform from the HashiCorp repository on an Ubuntu and Debian system:

1. Use wget and download the signing key to a new keyring:

wget -O- https://apt.releases.hashicorp.com/gpg | gpg --dearmor | sudo tee /usr/share/keyrings/hashicorp-archive-keyring.gpg
