Azure CustomScript 扩展未在 Centos 7.2 中执行

Question

我想在虚拟机部署后启动以下脚本，按照下面 URL 中提供的说明进行操作，并上传脚本和命令以在门户中执行

https://azure.microsoft.com/en-us/blog/automate-linux-vm-customization-tasks-using-customscript-extension/

这是我在 shell 脚本中的命令

{
    cd /tmp && wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
rpm -ivh epel-release-7-9.noarch.rpm 
yum install ansible -y 

{

部署虚拟机后，我看不到虚拟机内的脚本，也看不到虚拟机内的脚本的字体

然后我添加了命令 mkdir/tmp/test 来创建文件夹作为部署的一部分，此部署花费了超过 5 分钟，而且我看不到在虚拟机内创建的文件夹/tmp/test，

还在启动日志中观察到此错误

在扩展下看到此错误

根据你的描述，我在实验室进行了测试。你最好调整一下脚本格式。以下脚本是我的，它对我有用。

cd /tmp 
wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm
rpm -ivh epel-release-7-9.noarch.rpm 
yum install ansible -y 

当你没有得到预期的结果时，你可以检查/var/log/waagent.log，你会得到如下日志:

2017/02/07 01:49:53 CustomScriptForLinux started to handle.
2017/02/07 01:49:53 [Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.1] cwd is /var/lib/waagent/Microsoft.OSTCExtensions.CustomScriptForLinux-1.5.2.1

现在，您可以检查日志 /var/log/azure/Microsoft.OSTCExtensions.CustomScriptForLinux/1.5.2.1/extension.log

更新:如果您丢失了某些文件，您可以尝试卸载扩展程序并重新安装。
