linux 上的 powercli 腳本無法作為 systemctl 服務運行

Question

我正在嘗試創建一個 powercli 腳本 (ps1) 作為 systemctl 服務在 linux 上運行。 使用 pwsh 運行時腳本運行良好。 但是，當我將它變成一項服務時，它會失敗，就好像無法識別我在腳本中使用的 pwsh 命令一樣。

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

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

[Install]
WantedBy=multi-user.target

我在 journalctl 中看到的錯誤：

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.

為什么這個 pwsh 腳本可以正常運行，但作為 systemctl 服務執行時卻失敗了？

我設法解決它。 顯然，問題出在這一行：服務定義文件中的user=root 。 user應該大寫： User 。 所以它沒有以 root 身份運行它，因此無法訪問模塊。
