PHP 脚本导致服务器关闭

我有一台带有 4GB RAM 的 centos 服务器。我正在执行一个 PHP 控制台批处理，这可能需要几个小时……但是它没有完成，因为服务器在启动该过程 1 或 2 小时后关闭……以下是日志：

它启动清理的 php 会话文件然后突然停止所有服务并关闭！

我的代码看起来还好......我需要强制清理代码上的变量吗？

问题是什么？

谢谢

答案1

您的日志显示某个进程向 systemd 发送了信号导致其关闭，该进程的名称是kill。

Dec 28 04:40:04 www systemd[24724]: Received SIGRTMIN+24 from PID 11820 (kill).

最有可能的是用户手动执行了此操作，或者系统上运行的脚本向 PID 1 发送了信号（可能是错误的，意图发送其他 PID）。

您可能需要查看关机时打开的两个根用户会话。

答案2

您似乎相当确定服务器关闭是运行脚本的结果。如果是这样，那么脚本就会关闭服务器。如果您不想让服务器关闭，请更改脚本。

另一方面，如果不是脚本出错，则说明发生了其他问题。提高日志记录级别。
