我试图找出我的Apache
PHP崩溃的原因.我希望有一些设置,工具或某些东西来帮助追踪代码,配置或导致这些PHP崩溃的问题.
在我的Windows事件日志中我(显示apache崩溃,但由php引起)： Faulting application httpd.exe,version 2.2.21.0,time stamp 0x4e6b3136,faulting module php5ts.dll,version 5.3.8.0,time stamp 0x4e537a04,exception code 0xc0000005,fault offset 0x0000c7d7,process id 0xbf4,application start time 0x01cd45afc42f0b7d. 该应用程序在Windows Server 2008计算机(xampp)上使用Apache,PHP和MySQL. 这是我的Apache日志中的崩溃： [Fri Jun 08 15:56:34 2012] [notice] Parent: child process exited with status 3221225477 -- Restarting.

由于XAMPP的Apache(用于Windows)是使用
winn_nt MPM(多线程)线程安全PHP构建的,因此您可能会遇到所谓的PHP线程安全版本固有的问题(有关更多信息,请参阅
this very good post).这可以解释为什么在单用户模式下运行时从未遇到过错误.
如果Uku Loskit的建议有任何好处,请告诉我们.如果没有,我建议在这样的多用户环境中切换到Prefork Non-Thread-Safe PHP设置. 因为必须在编译时选择MPM,所以您需要： >自己编译Apache(技术上可行,但据我记得,在Windows的脖子上相当痛苦) 也许您最好尝试使用FastCGI运行PHP(这个额外的层基本上通过为每个线程启动单独的PHP进程来隔离服务器线程,以及much more).这应该可以让您轻松验证我的初始假设. 只是旁注：我没有看到在Windows Server上安装Apache的重点.您可能需要考虑使用IIS,可选择使用FastGCI(请参阅说明here),或者(更好)切换到基于Linux的堆栈. （编辑：李大同） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
