I am used to publish Azure WebApps on Windows but now I am trying to deploy an ASP.NET Core 3 (with NodeServices) to a Linux WebApp and I am receiving the following error message:
InvalidOperationException: Failed to start Node process. To resolve this:.
[1] Ensure that Node.js is installed and can be found in one of the PATH directories.
Current PATH enviroment variable is: /opt/dotnetcore-tools:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/home/site/wwwroot
Make sure the Node executable is in one of those directories, or update your PATH.
On Windows WebApps I have a lot of other apps and all are fine.
On Kudu I typed node -v and the output was v12.13.0.
Can anybody please help me?
Thank you very much.
After a long research and the assistance of Microsoft's Engineer https://github.com/caroe2014 this is the three steps final answer:
1) Startup.cs
services.AddNodeServices(options =>
{
if (RuntimeInformation.IsOSPlatform(OSPlatform.Linux))
{
options.ProjectPath = Path.GetFullPath("/home/site/wwwroot");
}
}
);
2) And what I found is Node is not present in the container so it is necessary to have a script to install and start it before starting the app itself. So I have this start1.cs file:
#!/bin/bash
apt-get install curl
curl -sL https://deb.nodesource.com/setup_12.x | bash
apt-get install -y nodejs
set -e
export PORT=8080
export ASPNETCORE_URLS=http://*:$PORT
dotnet "Web.Identity.dll"
Where Web.Identity.dll is the dll of my app.
3) Set startup command to /home/site/wwwroot/start1.sh (On Azure Portal - App service Configuration - or Azure DevOps).
That's all.
Try to mention the path in the code, This is how NodeServices was configured in Startup.cs:
services.AddNodeServices(options =>
{
options.ProjectPath = "Path\That\Doesnt\Exist";
});

We use automatic deployment process in Azure by KUDU scripts and by today we see strange error in Azure deployment center:
Command dotnet publish (and also 'dotnet build') returns:
MSBUILD : error MSB1025: An internal failure occurred while running MSBuild.

...
Details:
there is automatic deployment process by KUDU script
app is .NET Core application, .csproj has target framework: netcoreapp2.2
Issue probably will be on Azure side, because we did't do any bigger change in the project.
Has anybody same/similar issue?
We had the same issue and after investigation we found that:
Azure applied new 'dotnet' version 3.1.301 and this version of SDK throws that error (your version you can check by commnad 'dotnet --version')
by command 'dotnet --list-sdks' you can see all installed SDKs
then we simple used previous version (in our case v3.1.202)
the easiest way how to tell exact version of dotnet sdk is by global.json
Example:
global.json
{
"sdk": {
"version": "3.1.202"
}
}
And file must be in 'working directory', and KUDU script has working directory here D:\home\site\repository
When your deployment was OK on previous version of dotnet SDK, than this should definitely help.
This problem could also happen in other situations because of the sdk is installed as admin (e.g if installed with sudo).
In this case uninstalling the sdk and installing it as non-admin user could help resolve the issue. You can use this script to install for non-admin user.
e.g (tested on ubuntu 20.04):
$ wget https://dot.net/v1/dotnet-install.sh
$ chmod +x dotnet-install.sh
$ ./dotnet-install.sh -c Current
Add to the path and verify:
$ echo "export PATH=$HOME/.dotnet:$PATH" >> ~/.bashrc
$ exec bash
$ dotnet --version
3.1.402
NB: After doing this you may get an error error : Unable to obtain lock file access on '/tmp/NuGetScratch/lock then you could remove it and good to go.
sudo rm -r /tmp/NuGet*
I am trying to install dynamically windows services from my electron app.
For that i am using the node module "node-windows".
This looks like this:
service = new Service({
name: 'Watcher',
description: 'Watcher',
script: 'Watcher.js',
env: {
name: "SettingsPath",
value: storage.getDataPath()
}
});
service.on('install',function(){
service.start();
});
service.install();
this works very well on my dev machine.
The app requests for permission to create the service and installs it smoothly.
My Problem
If i compile the app to an exe the app doesnt request me for permissions and print an error
Permission Denied. Requires administrative privileges.
The app creates the service exe successfully at that time and doesnt do anything more.
Ok, so i started the app with admin privileges for testing this behavior.
Nice, the app doesnt show any error, creates the service exe AND ahhhhhh installed the service NOT.
Questions
Why does the app no longer ask for permissions when it is compiled?
Why isn't the service installed when the app is compiled?
If you need any additional information, write me a comment. And thanks for your time.
the path to the elevate.cmd in node-windows is incorrect for electron apps.
i have documented the way of trouble here
found some more problems to use the node-windows package:
cant use scripts from electron asar file (exclude files or diable
asar)
the executable path from the generated service config is wrong (its the packaged app executable, but must be node.exe or an equivalent executable)
service will only run on target system if node.js is installed, or you provide an equivalent
Can any node.js experts tell me how I might configure node JS to autostart a server when my machine boots?
I'm on Windows
This isn't something to configure in node.js at all, this is purely OS responsibility (Windows in your case). The most reliable way to achieve this is through a Windows Service.
There's this super easy module that installs a node script as a windows service, it's called node-windows (npm, github, documentation). I've used before and worked like a charm.
var Service = require('node-windows').Service;
// Create a new service object
var svc = new Service({
name:'Hello World',
description: 'The nodejs.org example web server.',
script: 'C:\\path\\to\\helloworld.js'
});
// Listen for the "install" event, which indicates the
// process is available as a service.
svc.on('install',function(){
svc.start();
});
svc.install();
p.s.
I found the thing so useful that I built an even easier to use wrapper around it (npm, github).
Installing it:
npm install -g qckwinsvc
Installing your service:
> qckwinsvc
prompt: Service name: [name for your service]
prompt: Service description: [description for it]
prompt: Node script path: [path of your node script]
Service installed
Uninstalling your service:
> qckwinsvc --uninstall
prompt: Service name: [name of your service]
prompt: Node script path: [path of your node script]
Service stopped
Service uninstalled
If you are using Linux, macOS or Windows pm2 is your friend. It's a process manager that handle clusters very well.
You install it:
npm install -g pm2
Start a cluster of, for example, 3 processes:
pm2 start app.js -i 3
And make pm2 starts them at boot:
pm2 startup
It has an API, an even a monitor interface:
Go to github and read the instructions. It's easy to use and very handy. Best thing ever since forever.
If I'm not wrong, you can start your application using command line and thus also using a batch file. In that case it is not a very hard task to start it with Windows login.
You just create a batch file with the following content:
node C:\myapp.js
and save it with .bat extention. Here myapp.js is your app, which in this example is located in C: drive (spcify the path).
Now you can just throw the batch file in your startup folder which is located at C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup
Just open it using %appdata% in run dailog box and locate to >Roaming>Microsoft>Windows>Start Menu>Programs>Startup
The batch file will be executed at login time and start your node application from cmd.
This can easily be done manually with the Windows Task Scheduler.
First, install forever.
Then, create a batch file that contains the following:
cd C:\path\to\project\root
call C:\Users\Username\AppData\Roaming\npm\forever.cmd start server.js
exit 0
Lastly, create a scheduled task that runs when you log on. This task should call the batch file.
I would recommend installing your node.js app as a Windows service, and then set the service to run at startup. That should make it a bit easier to control the startup action by using the Windows Services snapin rather than having to add or remove batch files in the Startup folder.
Another service-related question in Stackoverflow provided a couple of (apprently) really good options. Check out How to install node.js as a Windows Service. node-windows looks really promising to me. As an aside, I used similar tools for Java apps that needed to run as services. It made my life a whole lot easier. Hope this helps.
you should try this
npm forever

Use pm2 to start and run your nodejs processes on windows.
Be sure to read this github discussion of how to set up task scheduler to start pm2: https://github.com/Unitech/pm2/issues/1079
Here is another solution I wrote in C# to auto startup native node server or pm2 server on Windows.
I know there are multiple ways to achieve this as per solutions shared above. I haven't tried all of them but some third party services lack clarity around what are all tasks being run in the background. I have achieved this through a powershell script similar to the one mentioned as windows batch file. I have scheduled it using Windows Tasks Scheduler to run every minute. This has been quite efficient and transparent so far. The advantage I have here is that I am checking the process explicitly before starting it again. This wouldn't cause much overhead to the CPU on the server. Also you don't have to explicitly place the file into the startup folders.
function CheckNodeService ()
{
$node = Get-Process node -ErrorAction SilentlyContinue
if($node)
{
echo 'Node Running'
}
else
{
echo 'Node not Running'
Start-Process "C:\Program Files\nodejs\node.exe" -ArgumentList "app.js" -WorkingDirectory "E:\MyApplication"
echo 'Node started'
}
}
CheckNodeService
Simply use this, install, run and save current process list
https://www.npmjs.com/package/pm2-windows-startup
By my exp., after restart server, need to logon, in order to trigger the auto startup.
Need to create a batch file inside project folder.
Write this code in batch file
#echo off
start npm start
save batch file with myprojectname.bat
Go to run command and press window + R
Enter this command :- shell:common startup
Press ok then folder will be open.
Folder path like as C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp
You will be paste your myprojectname.bat file.
You can check also. Need to system restart.
Copied directly from this answer:
You could write a script in any language you want to automate this (even using nodejs) and then just install a shortcut to that script in the user's %appdata%\Microsoft\Windows\Start Menu\Programs\Startup folder
I have downloaded node.js executable. How can I run that executable as windows service?
I cannot use standard node.js installer, since I need to run multiple version of node.js concurrently.
Late to the party, but node-windows will do the trick too.
It also has system logging built in.
There is an API to create scripts from code, i.e.
var Service = require('node-windows').Service;
// Create a new service object

WinSer is a node.js friendly wrapper around the popular NSSM (Non-Sucking Service Manager)
From this blog
Next up, I wanted to host node as a service, just like IIS. This way
it’d start up with my machine, run in the background, restart
automatically if it crashes and so forth.
This is where nssm, the non-sucking service manager, enters the
picture. This tool lets you host a normal .exe as a Windows service.
Here are the commands I used to setup an instance of the your node
application as a service, open your cmd like administrator and type
following commands:
nssm.exe install service_name c:\your_nodejs_directory\node.exe c:\your_application_directory\server.js
net start service_name
I'm not addressing the question directly, but providing an alternative that might also meet your requirement in a more node.js fashion way.
Functionally the requirements are:
Have the logic (app) running in the background
Be able to start/stop the logic
Automatically start the logic when system boots up
These requirements can be satisfied by using a process manager (PM) and making the process manager start on system startup. Two good PMs that are Windows-friendly are:
PM2
forever
To make the PM start automatically, the most simple way is to create a scheduled task with a "At Startup" trigger:
Since qckwinsvc has not been updated for a while there's a new version called qckwinsvc2 (npm, github)
It now supports args passed to the service. It also keeps a local cache so you don't have to provide a path every time you want to perform an action
Use the now arg to start the service as soon as it's installed
qckwinsvc2 install name="Hello" description="Hello World" path="C:\index.js" args="--y" now
qckwinsvc2 uninstall name="Hello"
qckwinsvc2 list
The process manager + task scheduler approach I posted a year ago works well with some one-off service installations. But recently I started to design system in a micro-service fashion, with many small services talking to each other via IPC. So manually configuring each service has become unbearable.
Towards the goal of installing services without manual configuration, I created serman, a command line tool (install with npm i -g serman) to install an executable as a service. All you need to write (and only write once) is a simple service configuration file along with your executable. Run
serman install <path_to_config_file>
will install the service. stdout and stderr are all logged. For more info, take a look at the project website.
A working configuration file is very simple, as demonstrated below. But it also has many useful features such as <env> and <persistent_env> below.
<service>
<id>hello</id>
<name>hello</name>
<description>This service runs the hello application</description>
<executable>node.exe</executable>
<!--
{{dir}} will be expanded to the containing directory of your
config file, which is normally where your executable locates
-->
<arguments>"{{dir}}\hello.js"</arguments>
<logmode>rotate</logmode>
<!-- OPTIONAL FEATURE:
NODE_ENV=production will be an environment variable
available to your application, but not visible outside
of your application
-->
<env name="NODE_ENV" value="production"/>
<!-- OPTIONAL FEATURE:
FOO_SERVICE_PORT=8989 will be persisted as an environment
variable machine-wide.
-->
<persistent_env name="FOO_SERVICE_PORT" value="8989" />
</service>
