Cron守护程序错误与PHP Cron作业[关闭]

Question

所以我对 Cron Jobs 还很陌生，我在试图让这个特定的 cron 工作正常工作时遇到了困难。我想要的只是每天都可以访问一个 PHP 网页。通过访问 PHP 页面，cron 作业将激活其中向特定用户发送电子邮件的脚本。这是 cron 作业代码：

php -q /home/sitename/public_html/scripts/emailnotifications.php

不幸的是，每天凌晨 1 点，我都会收到此错误消息，但没有人收到他们的电子邮件。

我没有对服务器的 shell 访问权限或对任何服务器设置文件（php.ini 除外）的访问权限。我应该怎么做才能让这个脚本每天运行？

Answer 1

看起来您将完整的 php.ini 从 Windows 机器（可能是开发环境）复制到了运行某些 linux 发行版的远程服务器。

您的 xampp 提供的 php.ini 中列出的扩展在那里无法以这种方式工作。如果您确定要从您的开发机器复制整个 php.ini，（您很可能不需要），您可能必须删除或编辑 extension= 行以适应环境（它们很可能至少应该以.so 结尾并且有不同的路径）。检查每个与路径相关的设置也是明智的。

（在每个extension= 行中使用完整路径是愚蠢的，因为有extension_dir）
