PHP 脚本通过 Cronjob 在一台服务器上运行，但不在类似服务器上

Question

我在一台服务器 (VPS WHM) 上通过 cronjob 运行此脚本，并将所有内容复制到另一台具有相同类型的 VPS 和 WHM 的主机上。此脚本未在新服务器上运行，或未发送电子邮件。我曾尝试与提供商一起对其进行故障排除，但他们不知所措。我的问题是什么设置可能导致这样的问题？我似乎弄乱了服务器上的所有设置，几乎没有结果。任何有助于追踪此问题的信息，请告诉我，我将编辑问题。如果你有一个猜测也会有帮助，我只是在寻找新的眼光来解决这个问题。

日志中没有错误

Cron 是：10 4 * * * php /home/xxxxx/public_html/alert.php

您是否检查过新服务器上的 php-cli 错误日志？运行时可能会出错。如果日志中没有错误，那么它可能根本没有运行。尝试使用 php 命令手动触发作业，看是否成功，然后将其添加到 cron 并检查错误日志。
