How To Install Terraform on CentOS 8

In this tutorial, we will show you how to install Terraform on CentOS 8. For those of you who didn’t know, Terraform is a free and open-source Infrastructure automation tool by Hashicorp which is used to create, build and change using infrastructure as a code across various cloud providers like AWS, Azure cloud, GCP, Oracle cloud, and many others.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of Terraform on a CentOS 8.

Prerequisites

• A server running one of the following operating systems: CentOS 8.
• It’s recommended that you use a fresh OS install to prevent any potential issues
• A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.

Install Terraform on CentOS 8

Step 1. First of all, make sure that all packages are up to date.

sudo dnf update

sudo unzip terraform_1.0.0_linux_amd64.zip

Next, move the extracted setup to /usr/local/bin directory:

sudo mv terraform /usr/local/bin/
