linux terraform环境配置(创建cvm的例子)

两种办法：建议采用2（1我还没顾上验证）

terraform依赖go环境，go环境配置参考https://cloud.tencent.com/developer/article/1836994

1、参考https://github.com/tencentcloudstack/terraform-provider-tencentcloud#readme

需要Go1.13和Terraform 0.13

https://golang.org/dl/#go1.13

https://releases.hashicorp.com/terraform/0.13.0/

2、手动配置

terraform依赖go环境，go环境配置参考https://cloud.tencent.com/developer/article/1836994

terraform下载地址：https://releases.hashicorp.com/terraform/

找到terraform 0.13.x版本下载地址进行下载

我做实验时下载的terraform_0.13.0

http://releases.hashicorp.com/terraform/0.13.7/terraform_0.13.7_linux_amd64.zip

http://releases.hashicorp.com/terraform/0.13.6/terraform_0.13.6_linux_amd64.zip

http://releases.hashicorp.com/terraform/0.13.5/terraform_0.13.5_linux_amd64.zip

http://releases.hashicorp.com/terraform/0.13.2/terraform_0.13.2_linux_amd64.zip

http://releases.hashicorp.com/terraform/0.13.1/terraform_0.13.1_linux_amd64.zip

http://releases.hashicorp.com/terraform/0.13.0/terraform_0.13.0_linux_amd64.zip

http://windows-1251783334.cos.ap-shanghai.myqcloud.com/terraform_0.13.6_linux_amd64.zip

http://windows-1251783334.cos.ap-shanghai.myqcloud.com/terraform_0.13.7_linux_amd64.zip

# wget http://windows-1251783334.cos.ap-shanghai.myqcloud.com/terraform_0.13.0_linux_amd64.zip

# mkdir terraform_dir

# unzip terraform_0.13.0_linux_amd64.zip

# mv terraform terraform_dir/

# echo "export PATH=$PATH:/root/terraform_dir" >> /etc/profile && source /etc/profile

# cd terraform_dir/

# vim provider.tf

添加内容

provider "tencentcloud" {

secret_id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

secret_key = "yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy"

region = "ap-shanghai"

}

# terraform init

第一次执行 terraform init 会提醒让执行terraform 0.13upgrade

执行terraform 0.13upgrade后会提示让敲yes

敲完yes后会看到

紧接着再执行一次terraform init就会看到

敲 yes 后继续执行 terraform init

需要注意的是，有时候敲yes后再敲一遍terraform init就ok了，但有时候可能需要执行几次terraform init才能成功，例如下图

接下来就是编辑cvm.tf文件

vim cvm.tf

请注意里面的参数值请具体化成你自己的

}

编好后就可以执行terraform validate来验证是否存在语法问题，没问题的话就可以执行terraform plan了，注意执行terraform plan时加-out参数，因为光执行terraform plan会报

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.

去除这个报错的办法就是加-out参数，例如terraform plan -out test

然后就是执行terraform apply "test"

要销毁上面创建的cvm的话，执行terraform destroy

1.59.18之前的版本（本文档首次实验时，provider是1.59.14版本）

如果大家亲自试一遍的话，会发现 instance_count = 2跟count = 2都能创建2台机器出来，但是执行terraform destroy的话，instance_count = 2的情况只能销毁1台机器，因为创建机器的时候记录了1个instanceid，销毁的时候应该就是读创建时记录的那些个instanceid的，由于就记录了1个，所以销毁的时候也就销毁1个。

试了count = 2的情况下，创建的时候记录了2个instanceid，销毁的时候也记录了2个instanceid。

另外， instance_count = 2跟count = 2的情况在资源编排TIC上的表现跟在linux terraform环境中的表现一样。

估计instance_count = 2是个bug吧。

1.59.18及其之后的版本（本文档第二次实验时，provider是1.61.4），instance_count和count的情况正好反过来了。总之，1.59.18之前的版本用instance_count，1.59.18及其之后的版本用count，这问题是我反馈给腾讯云修正的
