Introduction

#

Terraform, a widely-used Infrastructure as Code tool, can be a game changer for your DevOps workflow. This article provides a step-by-step guide on how to install Terraform on Red Hat Enterprise Linux (RHEL) 9.3, ensuring a smooth setup for your infrastructure management.

Terraform and RHEL

#

Terraform by HashiCorp is an open-source tool that allows you to define and provision a datacenter infrastructure using a high-level configuration language. Red Hat Enterprise Linux (RHEL) is a popular and robust operating system, known for its stability and enterprise-level support, making it an excellent choice for running Terraform.

Prerequisites

#
  • Access to a RHEL 9.3 system
  • Sudo privileges
  • Internet connectivity

Installation Steps

#

1. Access Your RHEL System

#

Start by SSH-ing into your RHEL server:

ssh devops@rhel.example.com

Enter your password when prompted.

ssh devops@rhel.example.com
devops@rhel.example.com's password:
Activate the web console with: systemctl enable --now cockpit.socket
[devops@localhost ~]$

2. Switch to Root User

#

For installing packages system-wide, switch to the root user:

sudo su

Enter the sudo password for the 'devops' user.

[devops@localhost ~]$ sudo su
[sudo] password for devops:
[root@localhost devops]#

3. Verify RHEL Version

#

It's good practice to check your operating system details:

cat /etc/os-release

This confirms that you are running RHEL 9.3.

4. Install Yum-Utils

#

Yum-Utils provides utilities that integrate with Yum to enhance its default features, making it easier to manage packages.

yum install yum-utils

Confirm the installation by typing 'y' when prompted.

5. Add the HashiCorp Repository

#

HashiCorp provides a dedicated repository for their packages. Add it to your system:

yum-config-manager --add-repo https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo

The output look like the following:

Updating Subscription Management repositories.
Adding repo from: https://rpm.releases.hashicorp.com/RHEL/hashicorp.repo

6. Install Terraform

#

Now, install Terraform:

yum install terraform

Again, confirm by typing 'y'. Terraform and its dependencies will be installed.
