How to solve the problem that after Tencent cloud sets static DNS, restarting the machine becomes dynamic DNS acquisition

Set-ExecutionPolicy Unrestricted -force

while((powershell -c {(get-process|findstr powershell).length}) -ne 2)

{

get-date -format HH:mm:ss:fffffff >> c:\aaa.txt;

start-sleep 1;

}

if((powershell -c {(get-process|findstr powershell).length}) -eq 2)

{

(get-wmiobject -class win32_networkadapterconfiguration -filter ipenabled=true).SetDNSServerSearchOrder(('10.123.119.98','10.12.216.180')) 2>$null;

exit

}

Code to be fine tuned , Put it in C:\Program Files\Cloudbase Solutions\Cloudbase-Init\LocalScripts\setdns.ps1

dns Adjust the agent according to your own needs dns, You can add 、 reduce dns, for example ：

Add

(get-wmiobject -class win32_networkadapterconfiguration -filter ipenabled=true).SetDNSServerSearchOrder(('10.123.119.98','10.12.216.180','114.114.114.114','8.8.8.8')) 2>$null;

reduce

(get-wmiobject -class win32_networkadapterconfiguration -filter ipenabled=true).SetDNSServerSearchOrder(('180.76.76.76')) 2>$null;

This script is written by me to set the static DNS Of , For some machines , The value in the code is 2 You can set dns, No machine handle 2 Change to 3 You can set dns success ( The concrete is 2 still 3 Or a bigger number , I watched the background after the restart powershell Number of processes )

2 On behalf of others powershell It's all done , Is executed setdns.ps1 In itself , Set up dns In the last step

and 3 The situation is , I have observed that there are always 1 individual powershell, There has always been , This situation ,3 On behalf of others that should be completed powershell It's all done , Next, we will carry out setdns.ps1 In itself

In code 2 and 3 I have encountered both situations , because cloudbase-init By calling powershell The code works , I guess the logic 2 and 3 The difference may be that the user-defined image has a resident boot plan task, which is weak powershell The process is placed in the background , If that's the case , Excepting 2 and 3, There may be 4、5、6 , etc. , Specifically, it depends on the background after startup powershell How many processes are there
