一. 官網下載安裝包

安裝文檔?hashicorp給出的安裝文檔

文檔中包含下載地址，選擇CentOS 的安裝包點擊下載，格式為.zip

下載地址：https://www.terraform.io/downloads.html

安裝包鏈接：https://releases.hashicorp.com/terraform/0.12.28/terraform_0.12.28_linux_amd64.zip

二. 解壓到 /usr/local/bin目錄

下載完成后將 .zip解壓到 /usr/local/bin 目錄下，方便下一步配置PATH變量。解壓后的 terraform是一個 binary 可執行文件，如圖所示

解壓命令：

~$ 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. 檢查terraform是否安裝成功

直接在terminal中輸入terraform，如果上一步的PATH配置成功，terminal會提示以下信息

四. 測試百度云-對象存儲

? ?因為每個 Terraform 項目都需要創建 1 個獨立的工作目錄，所以先創建一個測試目錄?terraform-test。?

4.1 創建目錄

[root@test bin]#mkdir terraform-test

4.2 進入?terraform-test?目錄。

[root@test bin]#cd terraform-test [root@test terraform-test]#

4.3 創建配置文件。

Terraform 在運行時，會讀取該目錄空間下所有?*.tf 和?*.tfvars?文件。因此，您可以按照實際用途將配置信息寫入到不同的文件中。下面列出幾個常用的配置文件：

provider.tf -- provider 配置 terraform.tfvars -- 配置 provider 要用到的變量 varable.tf -- 通用變量 resource.tf -- 資源定義 data.tf -- 包文件定義 output.tf -- 輸出

例如：創建?provider.tf?文件時，您可按以下格式配置您的身份認證信息：

[root@test terraform-test]# vim main.tf provider "baiducloud" {access_key = "LTA*****************NO2"secret_key = "MOk8x0*************wwff"region = "bj" }

4.4 初始化工作目錄

[root@test terraform-test]#terraform initInitializing 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：預覽功能，允許在正式執行配置文件之前，查看將要執行哪些操作。

例如，您添加了創建 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" }# 創建源 bucket resource "baiducloud_bos_bucket" "source" {bucket = "charlietang"acl = "public-read-write" }

使用?terraform plan?可查看到將會執行的操作。

[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:+ createTerraform 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 創建 BOS?

terraform apply：執行工作目錄中的配置文件。

例如您想創建名為?charlietang 的 Bucket，您需要先添加創建 Bucket 的配置文件?main.tf。

[root@localhost baidu-cloud]# terraform applyAn execution plan has been generated and is shown below. Resource actions are indicated with the following symbols:+ createTerraform 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: yesbaiducloud_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 刪除?BOS?

terraform destroy：可刪除通過 Terraform 創建的空 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:- destroyTerraform 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: yesbaiducloud_bos_bucket.tangdd: Destroying... [id=charlietang1] baiducloud_bos_bucket.tangdd: Destruction complete after 1sDestroy complete! Resources: 1 destroyed.
