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

Question

Azure(和 Linux)新手...

CentOS 7.2 虚拟机。

我配置了一个新的 Azure CentOS VM，并为“Linux 自定义脚本”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

鲍勃.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

虚拟机部署后，我在仪表板上收到“部署失败”错误。

因为 Azure 认为我是一台计算机，所以以 JSON 格式向我显示的错误/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\"."
      }
    ]
  }
}

状态文件格式错误 (000003)无效状态/状态:失败？

先生。 DuckDuckGo 似乎没有关于此错误的信息。

我通过 SSH 连接到虚拟机:

文件 test.txt 不存在。

我尝试查看虚拟机上位于/var/log/azure/custom-script/handler.log 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个步骤。

有什么建议吗？

根据你的描述，我使用你的脚本并在我的实验室进行测试。我得到相同的错误日志。我检查 /var/log/azure/Microsoft.OSTCExtensions.CustomScriptForLinux‌​/1.5.2.1/extension.l‌​og 中的日志。我发现一些 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，即可成功安装扩展。

#!/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
