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

Question

Azure（和Linux）的新手...

CentOS 7.2 VM。

我配置一个新的Azure的CentOS的VM，并为 “自定义脚本用于Linux” 扩展以下： 脚本文件：bob.sh（从本地工作站的选择） 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 

VM部署完成后，仪表板上出现“部署失败”错误。

错误/状态消息，因为Azure的认为我是一台电脑，在JSON显示给我的是：

{ 
    "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\"." 
     } 
    ] 
    } 
} 

畸形状态文件（000003）无效的状态/状态：失败？

DuckDuckGo先生似乎没有关于此错误的信息。

我SSH到VM：

文件test.txt不存在。

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

我可以成功地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，我用你的脚本和测试在我的实验室。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.l‌​og。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，您可以成功安装扩展。

#!/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

对于文件可用在虚拟机上，只需上传到某个地方公开，并发出命令下载。看到这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')]" 
    } 
    } 
}
