IIS - Setting the physical path of an Application with appcmd - iis

In IIS, I have a web site "Default Web Site" with an application "test2". I want to set the physical path of that application to "E:\temp\out1". That directory already exists.
When I run this in Powershell (as an administrator):
appcmd.exe set app "Default Web Site/test2" -[path='/'].physicalpath:E:\temp\out1
I get this error message:
ERROR ( message:Malformed collection indexer; format is [#position,name='value',name2='value2',...]. The #position specifier is optional, and be '#start', '#end', or '#N' where N is a numeric index into the collection. )
I have no idea what that means.
Would very much appreciate a working example of using appcmd to set the physical path of an IIS application.

Turns out that the command in my question actually works on Command Prompt. However, I tried to run it from a Powershell prompt, and there I got the error message.
I couldn't find a way to run the command from Powershell. In the end, my solution was to write the command to a temporary .bat file, then execute that file from Powershell.

If I set my double quotes like this it works from Powershell prompt.
appcmd.exe set app "Default Web Site/test2" -"[path='/'].physicalpath:E:\temp\out1"

Azure Powershell - load variables from another script file

In Azure DevOps, I have an Azure Powershell task to create some resources using ps1 script in repo. This script working fine.
Now I need to split the script and variables into different files.
I created files SB-Config.ps1 for variables and ServiceBus.ps1 with main script. Moved all vars into SB-Config.ps1 .
Both files are in the same folder and in ServiceBus.ps1 I added:
. .\SB-Config.ps1
But Azure Devops fails with error:
What I'm doing wrong and how to get variables from SB-Config.ps1 script, when running ServiceBus.ps1 file?
I am able to reproduce your situation on my side.
Same issue as yours.
You can run this command to output the location of current work space:
Get-Location
I notice the powershell script file on your side is in the sub folder of Default working directory.
So do you set the work space in the powershell script file you are running first?
Set-Location $env:System_DefaultWorkingDirectory\subfolders
In your situation, I think the issue comes from the current work space is System_DefaultWorkingDirectory , the error output means the script can't get the file you want. This issue only occurs when you select 'file path' to run.

Creating/Migrating rBac in Yii2

I'm just getting started with Yii2 and I am following a tutorial here about setting up Yii2/AdminLTE and I am unable to finish the setup as I am getting errors in Terminal on the last step.
The part I am not able to finish is:
finaly we create rbac dbmanager with simple code, you can see in
folder "console/RbacController" with specific level for :
Admin : can do everything Editor : can edit, add and view Author : can
add and view viewer ; just viewer create rbac :
"yii migrate --migrationPath=#yii/rbac/migrations"
"yii rbac/init"
dont forget to chmod -R 777 on your web/assets if linux environment
and please free to update your setting on menu setting.
So in terminal on my mac, I tried both:
yii migrate --migrationPath=#yii/rbac/migrations
with the error: -bash: yii: command not found
and
/.yii migrate --migrationPath=#yii/rbac/migrations
with error: -bash: /.yii: No such file or directory.
I was able to complete the beginning of the tutorial, it is just this last step. I am already working in my yii2-advanced-adminlte directory
UPDATED:
Added screenshot of terminal window
Normally the yii command is located in
fro advanced template in project directory parent of backend, frontend, console and not in console
be sure of find the right dir and then accessing this try launche your command
yii migrate --migrationPath=#yii/rbac/migrations
eventually adjust your path to rbac/ migrations
Found it out, the problem was using MAMP I had to manually set the php bin to 5.5.23 in terminal because once I started down the path scaisEdge showed me I was getting a No such File or Folder error.
Eventually this is the command that worked for me (check your php MAMP path):
/Applications/MAMP/bin/php/php5.5.23/bin/php yii migrate

Java PATH not set when creating a Azure Paas Role

I am creating an Azure PaaS role which sets the PATH variable for java.exe .
I have a background task which does that.
The startupApp.cmd looks like
setx PATH %PATH%;%CD%\jdk\bin\ /m
cscript /NoLogo util\unzip.vbs jdk.zip "%CD%"
Call the bat file to start my application.
When the VM starts I see that the PATH environment variable is correctly set and points to where the jdk\bin folder. My application however fails to start with the error "java is not recognised as an internal or external batch command".
JAVA command to start my app is
java %JAVA_OPTS% %LOG_OPTS% %LOG4J_OPTS% -cp my_app.jar %MAIN_CLASS%
Here is the confusing path,
After I log into the VM and open a command prompt window and type java I see that it works fine.
If I restart the VM, the java command to bring up my app runs fine and I and my app too starts fine.
There is a significant difference between setx and set function:
set takes effect in local cmd context. Meaning once you exit or close the cmd window, you lose the environment variable.
setx takes effect in future cmd context. So you won't see the environment variable and its value in the current cmd. You need to open a new cmd window to see it.
If you want to use it global and immediate you should use both functions side by side.

Can't get azure web role to run locally using the emulator

I have a web role that I'm trying to run locally using the emulator. I have it working on another computer, but I cannot get it working on a different one, and have gone as far as to reformat it and start from scratch.
When I launch the site from Visual Studio, Chrome shows the following message:
This webpage is not available
The connection to 127.0.0.1 was interrupted.
There is also an error code listed at the bottom:
Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.
One interesting thing from the build output are these lines:
Starting process 'C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\Windows Azure Tools\v1.8\Debugger\WindowsAzureDebugger.exe' with arguments '"C:\Program Files\IIS Express\iisexpress.exe" /trace:error /config:"C:\Users\brian\AppData\Local\dftmp\Resources\159c7254-b7d0-4076-a4fd-820b00feca5f\temp\temp\RoleTemp\applicationHost.config" /site:"deployment18(27).AzureApp.MyApp.Web_IN_0_Web"'...
Process 'C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\Extensions\Microsoft\Windows Azure Tools\v1.8\Debugger\WindowsAzureDebugger.exe' exited with exit code 0.
If I run C:\Program Files\IIS Express\iisexpress.exe" /trace:error /config:"C:\Users\brian\AppData\Local\dftmp\Resources\159c7254-b7d0-4076-a4fd-820b00feca5f\temp\temp\RoleTemp\applicationHost.config" /site:"deployment18(27).AzureApp.MyApp.Web_IN_0_Web" from the command line, I get the following message:
The system cannot find the file specified.
Unable to start IIS Express in background.
I have no idea what file it cannot find, but I've verified that the config file I'm passing does in fact exist. Anyone have a clue what's going on here??
While I can not tell you what could be the actual root cause of your problem I can suggest a few ways to troubleshoot it:
Try changing IIS Express to Full IIS and see if it changes the behavior. You can do it by going to your Windows Azure Application project properties and look at "Web" option.
Try running application without debugging it
Launch CSrun at command prompt with /launchDebugger parameter of the /run option to verify that debugger does run without any issue
Try using IE as default browser
Clean your dftemp folder completely for any residual configuration and then launch Azure Emulator separately to verify there are no issues
Procmon "http://technet.microsoft.com/en-us/sysinternals/bb896645" may help you find the file that is missing...
Hopefully someone stumbles upon this answer with similar symptoms. When removing in role caching the <dataCacheClients> section was removed from . Somehow there was a left over <dataCacheClients> section left in the web.config. Everything and compiled and deployed to the emulator successfully. However, the role would fail to start since applicationHost.config was missing.
The fix was simply remove the unnecessary <dataCacheClients> section from the web.config file.

How to make startup tasks idempotent?

I have a number of startup tasks in batch files. In particular I call IIS's appcmd.exe to configure IIS. Startup tasks in Azure are supposed to idempotent (ie, able to be run repeatedly with the same results), in case the role is restarted for some reason. Unfortunately many of my IIS configuration commands will fail the second time around, eg because they delete a configuration node the first time which is then not present on subsequent runs.
My question is, how do I make these startup tasks idempotent? Is there a way to make appcmd.exe not throw errors? Is there a way to make the shell catch the errors? Is there a way to make the Azure framework ignore the errors?
Here's an example of my startup tasks. This is all contained in a command file, configiis.cmd.
#REM Enable IIS compression for application/json MIME type
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /+"dynamicTypes.[mimeType='application/json',enabled='True']" /commit:apphost
%windir%\system32\inetsrv\appcmd.exe set config -section:system.webServer/httpCompression /+"dynamicTypes.[mimeType='application/json; charset=utf-8',enabled='True']" /commit:apphost
#REM Set IIS to automatically start AppPools
%windir%\system32\inetsrv\appcmd.exe set config -section:applicationPools -applicationPoolDefaults.startMode:AlwaysRunning /commit:apphost
#REM Set IIS to not shut down idle AppPools
%windir%\system32\inetsrv\appcmd set config -section:applicationPools -applicationPoolDefaults.processModel.idleTimeout:00:00:00 /commit:apphost
#REM But don't automatically start the AppPools that we don't use, and do shut them down when idle
%windir%\system32\inetsrv\appcmd.exe set config -section:system.applicationHost/applicationPools "/[name='Classic .NET AppPool'].startMode:OnDemand" "/[name='Classic .NET AppPool'].autoStart:False" "/[name='Classic .NET AppPool'].processModel.idleTimeout:00:01:00" /commit:apphost
%windir%\system32\inetsrv\appcmd.exe set config -section:system.applicationHost/applicationPools "/[name='ASP.NET v4.0'].startMode:OnDemand" "/[name='ASP.NET v4.0'].autoStart:False" "/[name='ASP.NET v4.0'].processModel.idleTimeout:00:01:00" /commit:apphost
%windir%\system32\inetsrv\appcmd.exe set config -section:system.applicationHost/applicationPools "/[name='ASP.NET v4.0 Classic'].startMode:OnDemand" "/[name='ASP.NET v4.0 Classic'].autoStart:False" "/[name='ASP.NET v4.0 Classic'].processModel.idleTimeout:00:01:00" /commit:apphost
#REM remove IIS response headers
%windir%\system32\inetsrv\appcmd.exe set config /section:httpProtocol /-customHeaders.[name='X-Powered-By']
Aside from #Syntaxc4's answer: Consider the use of a breadcrumb (file) locally. In your script, check for existence of a known file (that you create). If it doesn't exist, go through your startup script, also creating a breadcrumb file. Next time the vm starts up, it would again check for existence of the breadcrumb file and, if it exists, exit the cmd file. If the breadcrumb file disappears, this typically means your vm has been reconstituted somewhere else (either a new instance or a respawned instance maybe on different hardware) and IIS configuration would be needed.
You would have to check to see if the config setting is present before attempting to delete it (add conditional logic). This could be achieved by:
'appcmd.exe list config -details'
Capturing a return value would give you something to compare against, be it length of output or an actual value.
MSDN now contains an excellent guide for doing this by handling error codes from APPCMD.
http://msdn.microsoft.com/en-us/library/windowsazure/hh974418.aspx
Basically after any appcmd operation, you can do the following:
IF %ERRORLEVEL% EQU 183 DO VERIFY > NUL
and ignore any acceptable error code.
Based on David Makogon's suggestion, I added the following to the top of each of my .cmd files. This seems to do the trick. It will create a flag file (what David called a breadcrumb file) in the same directory as the executing script, then check for it on subsequent runs.
#REM A file to flag that this script has already run
#REM because if we run it twice, it errors out and prevents the Azure role from starting properly
#REM %~n0 expands to the name of the currently executing file, without the extension
SET FLAGFILE=c:\%~n0-flag.txt
IF EXIST "%FLAGFILE%" (
ECHO %FLAGFILE% exists, exiting startup script
exit /B
) ELSE (
date /t > %FLAGFILE%
)
I highly recommend using the /config:* /xml on the end of your list command. For more information on how I made iis idempotent please look at: https://github.com/opscode-cookbooks/iis
Chef is one of multiple configuration management platforms and i'm only suggesting looking at it for the code (in ruby) that does idempotent via listing the current settings and comparing them to the settings being requested to change.
