Question

Azure（和Linux）的新手......

CentOS 7.2 VM。

我配置了一个新的Azure CentOS VM，并为“Custom Script for Linux”扩展设置了以下内容：脚本文件：bob.sh（从本地工作站选择）命令：sh bob.sh

bob.sh：

#!/bin/bash
sudo echo "This is a test" > test.txt

# Update instance packages
sudo yum -y check-update

# Download and install Node.js
sudo yum install -y epel-release
sudo yum install -y nodejs npm --enablerepo=epel

VM部署后，我在仪表板上出现“部署失败”错误。

由于Azure认为我是计算机，因此在JSON中向我显示的错误/状态消息是：

{
  "status": "Failed",
  "error": {
    "code": "ResourceDeploymentFailure",
    "message": "The resource operation completed with terminal provisioning state 'Failed'.",
    "details": [
      {
        "code": "VMExtensionProvisioningError",
        "message": "VM has reported a failure when processing extension 'CustomScriptForLinux'. Error message: \"Malformed status file (000003)Invalid status/status: failed\"."
      }
    ]
  }
}

格式错误的状态文件（000003）状态/状态无效：失败??

先生。 DuckDuckGo似乎没有关于此错误的信息。

我通过SSH进入虚拟机：

文件test.txt不存在。

我试图在/var/log/azure/custom-script/handler.log上查看VM上的日志文件，但我没有权限。

我可以成功手动运行脚本中的每一步。

有什么建议吗？

Answer 1

根据您的描述，我在您的实验室中使用您的脚本并进行测试。我得到相同的错误日志。我检查登录/var/log/azure/Microsoft.OSTCExtensions.CustomScriptForLinux‌/1.5.2.1/extension.l‌og。我发现了一些sudo错误。

请删除脚本中的sudo。 Azure以root用户身份执行脚本。删除sudo后，您可以成功安装扩展程序。

#!/bin/bash
echo "This is a test" > test.txt

# Update instance packages
yum -y check-update

# Download and install Node.js
yum install -y epel-release
yum install -y nodejs npm --enablerepo=epel

要使文件在VM上可用，只需将其上传到公共可用的位置并发出命令即可下载。见example

{
  "type": "Microsoft.Compute/virtualMachines/extensions",
  "name": "[concat(variables('vmName'),'/', variables('extensionName'))]",
  "apiVersion": "[variables('apiVersion')]",
  "location": "[resourceGroup().location]",
  "dependsOn": [
    "[concat('Microsoft.Compute/virtualMachines/', variables('vmName'))]"
  ],
  "properties": {
    "publisher": "Microsoft.Azure.Extensions",
    "type": "CustomScript",
    "typeHandlerVersion": "2.0",
    "autoUpgradeMinorVersion": true,
    "settings": {
      "fileUris": "[split(parameters('fileUris'), ' ')]", ## << file url goes here
      "commandToExecute": "[parameters('commandToExecute')]"
    },
    "protectedSettings": { ## << these are needed if you are using Azure Blob which is not publicly accessible
      "storageAccountName": "[parameters('customScriptStorageAccountName')]",
      "storageAccountKey": "[parameters('customScriptStorageAccountKey')]"
    }
  }
}

CustomScript扩展 - 无法在Azure CentOS VM上运行bash脚本
