在一臺服務器上通過Cronjob運行但未在類似服務器上運行的PHP腳本

Question

我在一臺服務器（VPS WHM）上通過cronjob運行此腳本，並將所有內容複製到具有相同類型VPS和WHM的另一臺主機上。此腳本未在新服務器上運行，或者電子郵件未被髮送。我試圖與提供商進行故障排除，他們不知所措。我的問題是什麼設置可能會導致這樣的問題？我看起來似乎已經與服務器上的每一個設置搞混了，而且幾乎沒有結果。任何有助於追蹤這些信息的信息，請告訴我，我將編輯該問題。如果你有一個猜測會有幫助，我只是在尋找新的眼睛來解決這個問題。

你是否檢查過新服務器上的php-cli錯誤日誌？運行時可能會出錯。如果日誌中沒有錯誤，那麼它可能根本不能運行。嘗試使用php命令手動觸發作業，看看它是否成功，然後將其添加到cron並檢查錯誤日誌。
