在虚拟机规模集中设置环境变量（Linux VM） [英] Setting environment variable in virtual machine scale set (Linux VM)

问题描述

大家好，

我正在尝试在所有比例集实例中设置环境变量。为此，我添加了custom_script_for_linux_extension。该脚本包含以下信息：

＃！/ bin / bash



导出用户=测试

导出密码= test123

export secrettoken = 67890-9877ghkl

退出

脚本已成功部署，但我看不到环境变量。这些实例有linux vm（ubuntu）。

我甚至尝试了以下信息，但遗憾的是部署失败，说它无法访问.profile或.bashrc

＃！/ bin / bash 
 
 if [-z" $ user" ] 
然后
 echo"设置用户信息" 
 echo" export user = test">>〜/ .profile 
 echo" export password = test123">>〜/ .profile 
 echo" export secrettoken = 67890-9877ghkl">>〜/ .profile 
 echo" export user = test">>〜/ .bashrc 
 echo" export password = test123">>〜/ .bashrc 
 echo" export secrettoken = 67890-9877ghkl">>〜/ .bashrc 
。 〜/ .bashrc 
。 〜/ .profile 
 
 else 
 echo"用户信息已经存在" 
 fi 
退出

我试图在我的java问题中获取环境变量。如何在azure vmss中设置环境变量，以便所有当前和自动调整的实例都有环境变量？

解决方案

我建议使用自定义图像而不是自定义脚本扩展来设置变量。

这将允许任何新的添加到您的比例集的实例使用预先配置的图像，其中已经设置了所有环境变量。 

Hello all,

I am trying to set environment variables in all scale-set instances. To do this, I added a custom_script_for_linux_extension. The script contained the following information:

#!/bin/bash

export user=test
export password=test123
export secrettoken=67890-9877ghkl

exit

The script deployed successfully but i could not see environment variables. The instances have linux vm (ubuntu).

I even tried the following information but unfortunately the deployment failed saying it cannot access .profile or .bashrc

#!/bin/bash

if [ -z "$user" ]
then
    echo "Setting user information"
    echo "export user=test">>~/.profile
    echo "export password=test123">>~/.profile
    echo "export secrettoken=67890-9877ghkl">>~/.profile
    echo "export user=test">>~/.bashrc
    echo "export password=test123">>~/.bashrc
    echo "export secrettoken=67890-9877ghkl">>~/.bashrc
    . ~/.bashrc
    . ~/.profile

else
      echo "user information is already present"
fi
exit

I am trying to get environment variables in my java problem. How do i set environment variables in azure vmss so that all the current and autoscaled instances have environment variables?

解决方案

I would suggest looking into using a Custom image instead of Custom Script Extension to set the variables. 

https://docs.microsoft.com/en-us/azure/virtual-machine-scale-sets/tutorial-use-custom-image-powershell

This will allow any new instances that get added to your scale set to use that preconfigured image where all the environment variables will already be set.
