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。

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

接下来，将提取的设置移动到目录：/usr/local/bin

sudo mv terraform /usr/local/bin/

现在可以通过运行一个简单的 terraform version 命令来验证安装：
