+1 very useful addition to the original doc.

+1 very useful thks

One hint also, if you want to set recovery parameters, i think sc -command is quite nice:

sc failure "ServiceName" actions= restart/60000/restart/60000/restart/60000 reset= 86400

This will restart service on first, second and subsequent failures after 1 minute (60000 ms) and will reset fail count after 1 days (86400 seconds).

Hi,

May I know how to switch the directory in NSSM, I need to run my service from particular folder.

After first line,
CD "C:\Program Files\nssm-2.24\win64"

I need to switch to the folder where I can run my service from there, tried with AppDirectory but no luck.. :(

Folks. I have a .net core console app. when ı use NSSM,a nuget package has been deleting automatically and stayed like that until ı stop service. Do you have any suggestion?

Outstanding, very useful +1

Super helpful! May I suggest adding a section for registry values that includes the cmd for setting them, like: Reg Add Regkey /v RegValue /t RegType /d data - maybe something like:

:: Set number of milliseconds to wait between restarts
Reg Add HKLM\System\CurrentControlSet\Services\servicename\Parameters\AppRestartDelay /v 2000 /t REG_DWORD

I would like to silently install a service for WildFly in a single command and include the user and password to run the service.

This is what I have so far:

nssm install Wildfly15 D:\wildfly-15.0.1.Final\bin\standalone.bat "-b=127.0.0.1 --debug"

This is OK. It opens the dialog box. Can nssm me used silently and can you add logon username and password?

I'm not sure @wagostin, I guess you're meaning you wish to control the "Run as" user for the service?

You're probably going to want to have a service account already part of your OS, which is then used by nssm as the run as user. I haven't touched nssm in years, so not even sure if that's possible.

Also include:
nssm remove SERVICE_NAME

i have a question, how to start multiple exe files at once? @magnetikonline

before i start exe file in cmd windows one by one, this is very stupid.

Because there is a dependency on the related exe startup, it has to be chain-started. Do you have relevant experience?

Due to the requirement that it cannot be deployed on docker and cannot be started in the cmd window, it must be packaged as a service through nssm。

@dybxin you'll probably have to make a PowerShell/batch file and execute that? Otherwise treat each exe as an isolated service.

@dybxin you'll probably have to make a PowerShell/batch file and execute that? Otherwise treat each exe as an isolated service.

likely: the following demo.bat file.

start /d "E:\minio\minio.exe" minio.exe server E:\minio\data

ping /n 10 127.0.0.1>nul

start /d "E:\demo\a.exe" a.exe -format=http

ping /n 10 127.0.0.1>nul

...

or

SETLOCAL
SET PATH="E:\demo\minio"

start /wait minio.exe server E:\demo\minio\data

SETLOCAL
SET PATH="E:\demo\xxx"

start /wait a.exe -format=http

start /wait b.exe -format=http

start /wait c.exe -format=http

I need to be able to stop and start the service under a standard user account. I have tried to use the runas command (See Below) but I have not had any luck to get it to work.

C:\windows\system32>runas /user:server\support /savecred "c:\kds\nssm stop KDS_MANAGER"
Attempting to start c:\kds\nssm stop KDS_MANAGER as user "server\support" ...

I see a window open and close very fast but the service does not stop

If I use "nssm stop KDS_MANAGER" on the same command prompt the service stops but this only works if the CMD prompt is run as administrator or I need to provide credentials. I am trying to get this to run without having to enter admin credentials.

I have also tried using batch files with no luck.

Any help to solve this would be greatly appreciated.

Regards,

Joe

How to fix program not executing at fast startup (fast boot)?
It's normal to restart windows. But shutdown and then on, the program will not be executed.

My node app running through nssm is restarting, again and again, every ~20 secs, but not showing any error. Any idea of which could be the cause? I'm running nssm start <service> through a cmd script in a cmd prompt with administrator rights.

Not sure, but you can silently remove services. nssm remove <servicename> confirm
