How to Install Terraform on RHEL 9

Prerequisites

Before installing Terraform on RHEL 9, ensure you have:

• Administrative/root access
• Internet connectivity
• A terminal or command prompt

Installation Steps

Step 1: Add the HashiCorp Repository

HashiCorp provides official packages for most platforms:

# Verify your system architecture
uname -m

Step 2: Install Terraform

Follow the official installation method for RHEL 9:

# Download the latest Terraform binary
# Visit: https://developer.hashicorp.com/terraform/downloads

Step 3: Verify Installation

# Check Terraform version
terraform version

# Expected output:
# Terraform v1.x.x
# on linux_amd64 (or your platform)

Post-Installation Setup

Configure Shell Autocompletion

# Install autocomplete
terraform -install-autocomplete

# Restart your shell
exec "$SHELL"

Set Up Your First Project

# Create a project directory
mkdir terraform-demo && cd terraform-demo

# Create main.tf
cat > main.tf << 'EOF'
terraform {
  required_version = ">= 1.5.0"
}

output "hello" {
  value = "Terraform is working on RHEL 9!"
}
EOF

# Initialize and run
terraform init
terraform apply -auto-approve

Managing Multiple Versions

For projects requiring different Terraform versions:

# Install tfenv (Terraform version manager)
git clone https://github.com/tfutils/tfenv.git ~/.tfenv
echo 'export PATH="$HOME/.tfenv/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

# Install specific version
tfenv install 1.7.5
tfenv use 1.7.5

# List installed versions
tfenv list

Common Issues

Permission Denied

# Fix binary permissions
chmod +x /usr/local/bin/terraform

Command Not Found

# Add to PATH
echo 'export PATH="$PATH:/usr/local/bin"' >> ~/.bashrc
source ~/.bashrc

Version Mismatch

# Check required version in your project
grep required_version *.tf

# Install matching version
tfenv install <version>

Next Steps

Now that Terraform is installed on RHEL 9:

1. Learn HCL syntax — HashiCorp Configuration Language basics
2. Set up a cloud provider — AWS, Azure, or GCP credentials
3. Create your first infrastructure — Start with a simple resource
4. Use remote state — Configure S3 or Terraform Cloud backend
5. Explore modules — Reuse configurations from the Terraform Registry
