一. 官网下载安装包
安装文档 hashicorp给出的安装文档
文档中包含下载地址，选择CentOS 的安装包点击下载，格式为.zip
下载地址：https://www.terraform.io/downloads.html
安装包链接：https://releases.hashicorp.com/terraform/0.12.28/terraform_0.12.28_linux_amd64.zip
二. 解压到 /usr/local/bin目录
下载完成后将 .zip解压到 /usr/local/bin 目录下，方便下一步配置PATH变量。解压后的 terraform是一个 binary 可执行文件，如图所示
解压命令：
~$ unzip terraform_0.12.28_linux_amd64.zip -d /usr/local/bin/
~$ cd /usr/bin
~$ sudo ln -s /usr/local/bin/terraform
~$ source ~/.bash_profile三. 检查terraform是否安装成功
直接在terminal中输入terraform，如果上一步的PATH配置成功，terminal会提示以下信息
四. 测试百度云-对象存储
因为每个 Terraform 项目都需要创建 1 个独立的工作目录，所以先创建一个测试目录 terraform-test。
4.1 创建目录
[root@test bin]#mkdir terraform-test4.2 进入 terraform-test 目录。
[root@test bin]#cd terraform-test
[root@test terraform-test]#4.3 创建配置文件。
Terraform 在运行时，会读取该目录空间下所有 *.tf 和 *.tfvars 文件。因此，您可以按照实际用途将配置信息写入到不同的文件中。下面列出几个常用的配置文件：
provider.tf -- provider 配置
terraform.tfvars -- 配置 provider 要用到的变量
varable.tf -- 通用变量
resource.tf -- 资源定义
data.tf -- 包文件定义
output.tf -- 输出例如：创建 provider.tf 文件时，您可按以下格式配置您的身份认证信息：
[root@test terraform-test]# vim main.tf
provider "baiducloud" {
access_key = "LTA*****************NO2"
secret_key = "MOk8x0*************wwff"
region = "bj"
}4.4 初始化工作目录
[root@test terraform-test]#terraform init
Initializing provider plugins...
- Checking for available provider plugins on https://releases.hashicorp.com...
- Downloading plugin for provider "alicloud" (1.25.0)...4.5 Terraform 管理 BOS
terraform plan：预览功能，允许在正式执行配置文件之前，查看将要执行哪些操作。
例如，您添加了创建 Bucket 的配置文件 test.tf ：
[root@test terraform-test]#vim main.tf
provider "baiducloud" {
access_key = "LTA*****************NO2"
secret_key = "MOk8x0*************wwff"
region = "bj"
}
# 创建源 bucket
resource "baiducloud_bos_bucket" "source" {
bucket = "charlietang"
acl = "public-read-write"
}
使用 terraform plan 可查看到将会执行的操作。
[root@test terraform-test]# terraform plan
Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.
------------------------------------------------------------------------
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:
# baiducloud_bos_bucket.tangdd will be created
+ resource "baiducloud_bos_bucket" "tangdd" {
+ acl = "public-read-write"
+ bucket = "charlietang1"
+ creation_date = (known after apply)
+ force_destroy = false
+ id = (known after apply)
+ location = (known after apply)
+ owner_id = (known after apply)
+ owner_name = (known after apply)
+ server_side_encryption_rule = (known after apply)
+ storage_class = "STANDARD"
}
Plan: 1 to add, 0 to change, 0 to destroy.
------------------------------------------------------------------------
Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.
4.6 Terraform 创建 BOS
terraform apply：执行工作目录中的配置文件。
例如您想创建名为 charlietang 的 Bucket，您需要先添加创建 Bucket 的配置文件 main.tf。
[root@localhost baidu-cloud]# terraform apply
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:
# baiducloud_bos_bucket.tangdd will be created
+ resource "baiducloud_bos_bucket" "tangdd" {
+ acl = "public-read-write"
+ bucket = "charlietang1"
+ creation_date = (known after apply)
+ force_destroy = false
+ id = (known after apply)
+ location = (known after apply)
+ owner_id = (known after apply)
+ owner_name = (known after apply)
+ server_side_encryption_rule = (known after apply)
+ storage_class = "STANDARD"
}
Plan: 1 to add, 0 to change, 0 to destroy.
Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.
Enter a value: yes
baiducloud_bos_bucket.tangdd: Creating...
baiducloud_bos_bucket.tangdd: Creation complete after 2s [id=charlietang1]
Apply complete! Resources: 1 added, 0 changed, 0 destroyed.
4.7 Terraform 删除 BOS
terraform destroy：可删除通过 Terraform 创建的空 Bucket。
[root@localhost baidu-cloud]# terraform destroy
baiducloud_bos_bucket.tangdd: Refreshing state... [id=charlietang1]
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
- destroy
Terraform will perform the following actions:
# baiducloud_bos_bucket.tangdd will be destroyed
- resource "baiducloud_bos_bucket" "tangdd" {
- acl = "public-read-write" -> null
- bucket = "charlietang1" -> null
- creation_date = "2020-07-08T06:47:52Z" -> null
- force_destroy = false -> null
- id = "charlietang1" -> null
- location = "bj" -> null
- owner_id = "3b4c0907265d49daa7fbf103bb2cba4a" -> null
- owner_name = "UC:29883996" -> null
- server_side_encryption_rule = "none" -> null
- storage_class = "STANDARD" -> null
}
Plan: 0 to add, 0 to change, 1 to destroy.
Do you really want to destroy all resources?
Terraform will destroy all your managed infrastructure, as shown above.
There is no undo. Only 'yes' will be accepted to confirm.
Enter a value: yes
baiducloud_bos_bucket.tangdd: Destroying... [id=charlietang1]
baiducloud_bos_bucket.tangdd: Destruction complete after 1s
Destroy complete! Resources: 1 destroyed.
