【问题描述】：

我通过 terraform 在 aws 中创建了一个自定义 vpc，其中包含 1 个公共子网和 2 个私有子网。现在我需要通过 Terraform 在私有子网中启动一个运行 apache 的实例。我在私有子网中启动一个实例的代码是这样的

resource "aws_instance" "my_apache" {
    ami = "ami-8437a5e4"
    key_name = "clust"
    subnet_id = "${aws_subnet.my_private1.id}"
    vpc_security_group_ids = ["sg-40542d3b"]
    availability_zone = "us-west-2a"
    instance_type = "t2.micro"
    tags {
      Name = "apache"
      }
      provisioner "remote-exec" {
        inline = [
          "sudo apt-get update",
          "sudo apt-get install apache2",
          "sudo service apache2 start"
        ]
      }
}

实例正在启动，但 apache 服务器未在实例中运行。我收到类似 dis 的错误。

aws_instance.my_apache (remote-exec): Connecting to remote host via SSH...
aws_instance.my_apache (remote-exec):   Host: 172.16.2.163

aws_instance.my_apache (remote-exec):   Private key: false

aws_instance.my_apache (remote-exec):   Private key: false
aws_instance.my_apache (remote-exec):   SSH Agent: true

它一直在继续。

可能是什么问题？如何让 apache 在该实例中运行？

【问题讨论】：

您在运行 terraform 的地方有什么样的连接？看起来它无权访问私有子网以连接到您的实例以运行配置

标签： amazon-web-services terraform

【解决方案1】：

首先，您要在私有子网中创建实例，因此请确保您已从运行 terraform 的机器连接到您的实例。

您的日志指定的第二件事：

aws_instance.my_apache (remote-exec):   Password: false
aws_instance.my_apache (remote-exec):   Private key: false

使用provisnors连接：

 connection {
    type     = "ssh"
    user     = "root"
    private_key = "${var.private_key}"
}
