linux 上的 powercli 脚本无法作为 systemctl 服务运行

Question

I'm trying to create a powercli script (ps1) to run on linux as a systemctl service. The script is working fine when running with pwsh. But when I turn it into a service it fails as if not recognizing the pwsh commands that I'm using in the script.

[Unit]
Description=test
After=network-online.target

[Service]
user=root
ExecStart=/usr/bin/pwsh /build/test/test.ps1

[Install]
WantedBy=multi-user.target

The error I see in journalctl:

Connect-VIServer: /build/test.ps1:7

(7.2.4:A:80) [NamedPipeIPC_ServerListenerError:NamedPipe.Exception.Error] An error has occurred in PowerShell IPC listening thread on process: 61158 in AppDomain: None.  Error Message: Operation canceled.

Why does this pwsh script runs fine normally but fails when executed as a systemctl service?

Answer 1

I manage to solve it. Apparently, the issue was with this line: user=root in the service definition file. user should be with capital: User . So it didn't run it as root and therefore couldn't access the modules.
