二、问题

1.Windows如何申明RAM 相关变量

（1）申明 （仅测试）

setx  TF_VAR_access_key  XXXXX
setx  TF_VAR_secret_key  XXXXX
setx  TF_VAR_region  cn-nanjing

（2）查看

regedit用户变量：
计算机\HKEY_CURRENT_USER\Environment系统变量：
计算机\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment

注册应用表：

用户变量：

系统变量：

2.Linux如何申明RAM 相关变量

（1）申明

export TF_VAR_access_key="XXXXX"
export TF_VAR_secret_key="XXXXX"
export TF_VAR_region="cn-nanjing"

3. Linux terraform 初始化失败

（1）报错

（2）原因分析

国内用户在下载 Provider 时会遇到下载缓慢甚至下载失败的问题

（3）解决方法

Terraform CLI 自 0.13.2 版本起提供了设置网络镜像的功能。为解决以上问题，阿里云 Provider 提供了镜像服务以帮助国内用户快速下载。

①配置方案

创建.terraformrc 或terraform.rc配置文件，文件位置取决于主机的操作系统。在 Windows 环境上，文件必须命名为terraform.rc，并放置在相关用户的%APPDATA%目录中。这个目录的物理位置取决于Windows 版本和系统配置；在 PowerShell 中使用 $env:APPDATA 可以找到其在系统上的位置。在所有其他系统上，必须将该文件命名为.terraformrc，并直接放在相关用户的主目录中。也可以使用TF_CLI_CONFIG_FILE环境变量指定 Terraform CLI 配置文件的位置，任何此类文件都应遵循命名模式*.tfrc。

②  在home目录下创建.terraformrc文件，内容如下

provider_installation {network_mirror {url = "https://mirrors.aliyun.com/terraform/"// 限制只有阿里云相关 Provider 从国内镜像源下载include = ["registry.terraform.io/aliyun/alicloud", "registry.terraform.io/hashicorp/alicloud",]   }direct {// 声明除了阿里云相关Provider, 其它Provider保持原有的下载链路exclude = ["registry.terraform.io/aliyun/alicloud", "registry.terraform.io/hashicorp/alicloud",]  }
}

③ 新增配置文件

vim .terraformrc
cd terraform/

④ 成功

4.Linux terraform 计划与预览失败

（1）报错

（2）原因分析

环境变量引用失败

（3）解决方法

重新申明变量

export TF_VAR_access_key="XXXXX"
export TF_VAR_secret_key="XXXXX"
export TF_VAR_region="cn-nanjing"

成功：

5. Windows terraform 初始化失败

 （1）报错

显示成功，实际未加载插件

（2）原因分析

国内用户在下载 Provider 时会遇到下载缓慢甚至下载失败的问题

（3）解决方法

Terraform CLI 自 0.13.2 版本起提供了设置网络镜像的功能。为解决以上问题，阿里云 Provider 提供了镜像服务以帮助国内用户快速下载。

①  配置方案

创建.terraformrc 或terraform.rc配置文件，文件位置取决于主机的操作系统。在 Windows 环境上，文件必须命名为terraform.rc，并放置在相关用户的%APPDATA%目录中。这个目录的物理位置取决于Windows 版本和系统配置；在 PowerShell 中使用 $env:APPDATA 可以找到其在系统上的位置。在所有其他系统上，必须将该文件命名为.terraformrc，并直接放在相关用户的主目录中。也可以使用TF_CLI_CONFIG_FILE环境变量指定 Terraform CLI 配置文件的位置，任何此类文件都应遵循命名模式*.tfrc。

② 查看目录

echo $env:APPDATA

③ 进入目录

④在相关目录下创建terraform.rc文件

内容如下：

provider_installation {network_mirror {url = "https://mirrors.aliyun.com/terraform/"// 限制只有阿里云相关 Provider 从国内镜像源下载include = ["registry.terraform.io/aliyun/alicloud", "registry.terraform.io/hashicorp/alicloud",]   }direct {// 声明除了阿里云相关Provider, 其它Provider保持原有的下载链路exclude = ["registry.terraform.io/aliyun/alicloud", "registry.terraform.io/hashicorp/alicloud",]  }
}

⑤ 成功

6. Windows terraform plan命令有哪些参数

（1）语法

PS C:\Gocode\src\TERRAFORM> terraform plan -help                       
Usage: terraform [global options] plan [options]Generates a speculative execution plan, showing what actions Terraformwould take to apply the current configuration. This command will notactually perform the planned actions.You can optionally save the plan to a file, which you can then pass tothe "apply" command to perform exactly the actions described in the plan.Plan Customization Options:The following options customize how Terraform will produce its plan. Youcan also use these options when you run "terraform apply" without passingit a saved plan, in order to plan and apply in a single command.-destroy            Select the "destroy" planning mode, which creates a planto destroy all objects currently managed by thisTerraform configuration instead of the usual behavior.-refresh-only       Select the "refresh only" planning mode, which checkswhether remote objects still match the outcome of themost recent Terraform apply but does not propose anyactions to undo any changes made outside of Terraform.-refresh=false      Skip checking for external changes to remote objectswhile creating the plan. This can potentially makeplanning faster, but at the expense of possibly planningagainst a stale record of the remote system state.-replace=resource   Force replacement of a particular resource instance usingits resource address. If the plan would've normallyproduced an update or no-op action for this instance,Terraform will plan to replace it instead. You can usethis option multiple times to replace more than one object.-target=resource    Limit the planning operation to only the given module,resource, or resource instance and all of itsdependencies. You can use this option multiple times toinclude more than one object. This is for exceptionaluse only.-var 'foo=bar'      Set a value for one of the input variables in the rootmodule of the configuration. Use this option more thanonce to set more than one variable.-var-file=filename  Load variable values from the given file, in additionto the default files terraform.tfvars and *.auto.tfvars.Use this option more than once to include more than onevariables file.Other Options:-compact-warnings          If Terraform produces any warnings that are notaccompanied by errors, shows them in a more compactform that includes only the summary messages.-detailed-exitcode         Return detailed exit codes when the command exits.This will change the meaning of exit codes to:0 - Succeeded, diff is empty (no changes)1 - Errored2 - Succeeded, there is a diff-generate-config-out=path  (Experimental) If import blocks are present inconfiguration, instructs Terraform to generate HCLfor any imported resources not already present. Theconfiguration is written to a new file at PATH,which must not already exist. Terraform may stillattempt to write configuration if the plan errors.-input=true                Ask for input for variables if not directly set.-lock=false                Don't hold a state lock during the operation. Thisis dangerous if others might concurrently runcommands against the same workspace.-lock-timeout=0s           Duration to retry a state lock.-no-color                  If specified, output won't contain any color.-out=path                  Write a plan file to the given path. This can beused as input to the "apply" command.-parallelism=n             Limit the number of concurrent operations. Defaultsto 10.-state=statefile           A legacy option used for the local backend only.See the local backend's documentation for moreinformation.
