How to Install Terraform v1.0.0 in CentOS 8 / Ubuntu 21.04

What is Terraform?

Terraform is a popular cloud orchestration tool in the world of automation, which is used to deploy your infrastructure through the IAC (Infrastructure as code) approach. Terraform is built by Hashicorp and released under Mozilla Public License.

Supports:
  • Public cloud
  • Private cloud
  • Hybrid cloud

Includes popular providers such as AWS, Azure cloud, GCP, Oracle cloud, and many others.

All you need is to download the terraform binary to your local/server machine which is going to act as your base machine.

Then Terraform will download the plugin for that particular provider automatically and will authenticate with provider API to execute the plan.

Infrastructure as Code

he process of provisioning and managing resources like Virtual Machine, Storage, Network, Database, etc.. through machine-readable definition files, rather than interactive tools or hardware configurations.

Features
  • Open-source.
  • Declarative syntax.
  • Pluggable Modules.
  • Immutable infrastructure.
  • Simple client-only architecture.

Installing Terraform in Linux Distributions

The Terraform primary distribution packages come in .zip  format, which includes single executable files that you can decompress any location on your Linux system.

Install Terraform in RHEL, CentOS & Fedora

Method (1)

To install Terraform on CentOS, start by updating the repository lists:

sudo yum update

So You’ll need wget and unzip – if you don’t have them, install them by entering:

sudo yum install wget unzip

Download Terraform from the developer’s website:

sudo wget https://releases.hashicorp.com/terraform/1.0.0/terraform_1.0.0_linux_amd64.zip

Extract the downloaded file:

unzip ./terraform_1.0.0_linux_amd64.zip -d  /usr/local/bin

The output confirms that the files are now located in the /usr/local/bin directory.

Lastly, verify that Terraform accepts commands:

terraform --version

The system should display Terraform v.1.0.0.

Note:

So To install the latest version from developers website visit this link and choose the latest:

By the way, the latest version right now is Terraform v1.0.0

Method (2)

However, for simpler integration with configuration management tools, terraform also offers package repositories for Debian-based and RHEL-based systems, which enables you to install Terraform using your default package management tools called APT and Yum.

All you have to do just follow the below commands :

$ sudo yum install -y yum-utils
$ sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/$release/hashicorp.repo
$ sudo yum update
$ sudo yum install terraform

Install Terraform in Debian, Ubuntu & Mint

Method (1)

So as the same as we did in CentOs we will follow the steps:

Before you download Terraform, update the repository lists:

sudo apt-get update

If your system does not have the wget and unzip utilities, use the following to install them:

sudo apt-get install wget unzip

So Run the wget utility to download Terraform:

sudo wget https://releases.hashicorp.com/terraform/1.0.0/terraform_1.0.0_linux_amd64.zip

So This is an example of the output:

Once the download finishes, extract the files:

sudo unzip ./terraform_1.0.0_linux_amd64.zip -d /usr/local/bin

Next, verify that Terraform accepts commands:

terraform version

Also The output should display Terraform v.1.0.0.

Method (2)

Also for simpler integration with configuration management tools, with package repositories follow these commands:

$ curl -fsSL https://apt.releases.hashicorp.com/gpg | sudo apt-key add -

$ sudo apt-add-repository "deb [arch=$(dpkg --print-architecture)] https://apt.releases.hashicorp.com $(lsb_release -cs) main"

$ sudo apt update

$ sudo apt install terraform

Now the installation can be verified by running a simple terraform version command.

$ terraform --version
