在本教程中，我们将向您展示如何在 CentOS 8 上安装 Terraform。对于那些不知道的人，Terraform 是 Hashicorp 的免费开源基础设施自动化工具，用于创建、构建和更改基础设施作为跨各种云提供商（如 AWS、Azure 云、GCP、Oracle 云等）的代码。

本文假设您至少具备 Linux 的基本知识，知道如何使用 shell，最重要的是，您将站点托管在自己的 VPS 上。 安装非常简单，假设您在 root 帐户中运行，否则您可能需要添加 ‘sudo‘ 到获得 root 权限的命令。 我将向您展示在 CentOS 8 上逐步安装 Terraform。

在 CentOS 8 上安装 Terraform

步骤 1. 首先，确保所有软件包都是最新的。

sudo dnf update

步骤 2. 在 CentOS 8 上安装 Terraform。

运行以下命令以从以下位置下载最新的 terraform 设置 Terraform 官方网站：

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