Question

我尝试使用remote-exec在目标VM上执行多个命令，但是失败并显示“ bash：权限被拒绝”，这是代码：

  connection {
    host        = "${azurerm_network_interface.nic.private_ip_address}"
    type        = "ssh"
    user        = "${var.mp_username}"
    private_key = "${file(var.mp_vm_private_key)}"
  }

  provisioner "remote-exec" {
    inline = [
      "sudo wget https://raw.githubusercontent.com/Microsoft/OMS-Agent-for-Linux/master/installer/scripts/onboard_agent.sh",
      "sudo chown ${var.mp_username}: onboard_agent.sh",
      "sudo chmod +x onboard_agent.sh",
      "./onboard_agent.sh -w ${azurerm_log_analytics_workspace.workspace.workspace_id} -s ${azurerm_log_analytics_workspace.workspace.primary_shared_key} -d opinsights.azure.us"
    ]
  }

在这里检查问题后：https://github.com/hashicorp/terraform/issues/5397，我需要将所有命令包装到一个文件中。然后，我使用模板文件将所有命令放入其中：

OMSAgent.sh

#!/bin/bash
sudo wget https://raw.githubusercontent.com/Microsoft/OMS-Agent-for-Linux/master/installer/scripts/onboard_agent.sh
sudo chown ${username}: onboard_agent.sh
sudo chmod +x onboard_agent.sh
./onboard_agent.sh -w ${workspaceId} -s ${workspaceKey} -d opinsights.azure.us

代码更改为：

data "template_file" "extension_data" {
  template = "${file("templates/OMSAgent.sh")}"

  vars = {
    workspaceId  = "${azurerm_log_analytics_workspace.workspace.workspace_id}"
    workspaceKey = "${azurerm_log_analytics_workspace.workspace.primary_shared_key}"
    username = "${var.mp_username}"
  }
}

resource "null_resource" "remote-provisioner" {
  connection {
    host        = "${azurerm_network_interface.nic.private_ip_address}"
    type        = "ssh"
    user        = "${var.mp_username}"
    private_key = "${file(var.mp_vm_private_key)}"
    script_path = "/home/${var.mp_username}/OMSAgent.sh"
  }

  provisioner "file" {
    content = "${data.template_file.extension_data.rendered}"
    destination  = "/home/${var.mp_username}/OMSAgent.sh"
  }

  provisioner "remote-exec" { 
    inline = [
      "chmod +x /home/${var.mp_username}/OMSAgent.sh",
      "/home/${var.mp_username}/OMSAgent.sh"
    ]
  }
}

但是在null_resource中似乎出了点问题，空资源安装停止并抛出此错误：

null_resource.remote-provisioner (remote-exec): /home/user/OMSAgent.sh: 2: /home/user/OMSAgent.sh: Cannot fork

shell脚本的内容是这样的：

cat OMSAgent.sh
#!/bin/sh
chmod +x /home/user/OMSAgent.sh
/home/user/OMSAgent.sh

似乎我用错误的方式编写了脚本。

@joe huang请确保您使用为虚拟机创建os_profile时提供的用户名和密码：

os_profile {
    computer_name  = "hostname"
    admin_username = "testadmin"
    admin_password = "Password1234!"
  }
