Run batch file as a Windows service
In order to run one application, a batch file has to be kicked off (which does things like start Jetty, display live logs, etc). The application will work only if this batch file is running. I am hence forced to have this batch file running and not logout from the Windows server.
Can this batch file be run as a service? I am experimenting with one of the suggestions from a similar question.
NSSM is totally free and hyper-easy, running command prompt / terminal as administrator:
nssm install "YourCoolServiceNameLabel"
then a dialog will appear so you can choose where is the file you want to run.
nssm remove "YourCoolServiceNameLabel"

Why not simply set it up as a Scheduled Task that is scheduled to run at start up?
There's a built in windows cmd to do this: sc create. Not as fancy as nssm, but you don't have to download an additional piece of software.
sc create "ServiceName" start= demand displayname= "DisplayName" binpath= [path to .bat file]
- start=demand means you must start the service yourself
- whitespace is required after
- I did encounter an error on service start that the service did not respond in a timely manner, but it was clear the service had run the .bat successfully. Haven't dug into this yet but this thread experienced the same thing and solved it using nssm to install the service.
No need for extra software. Use the task scheduler -> create task -> hidden. The checkbox for hidden is in the bottom left corner. Set the task to trigger on login (or whatever condition you like) and choose the task in the actions tab. Running it hidden ensures that the task runs silently in the background like a service.
Note that you must also set the program to run "whether the user is logged in or not" or the program will still run in the foreground.
On Windows 2019 Server, you can run a Minecraft java server with these commands:
sc create minecraft-server DisplayName= "minecraft-server" binpath= "cmd.exe /C C:\Users\Administrator\Desktop\rungui1151.lnk" type= own start= auto
The .lnk file is a standard windows shortcut to a batch file.
--- .bat file begins ---
java -Xmx40960M -Xms40960M -d64 -jar minecraft_server.1.15.1.jar
--- .bat file ends ---
All this because:
service does not know how to start in a folder,
cmd.exe does not know how to start in a folder
Starting the service will produce "timely manner" error, but the log file reveals the server is running.
If you need to shut down the server, just go into task manager and find the server java in background processes and end it, or terminate the server from in the game using the /stop command, or for other programs/servers, use the methods relevant to the server.
As Doug Currie says use RunAsService.
From my past experience you must remember that the Service you generate will
- have a completely different set of environment variables
- have to be carefully inspected for rights/permissions issues
- might cause havoc if it opens dialogs asking for any kind of input
not sure if the last one still applies ... it was one big night mare in a project I worked on some time ago.
