Apache服务器不断崩溃，“发现了SIGTERM，正在关闭”

问题描述：

这种情况刚刚发生在三周前。我的网站内容没有改变，它只是一个使用MySQL作为后端的phpBB论坛。Apache服务器不断崩溃，“发现了SIGTERM，正在关闭”

一年来没有任何变化，但最近，每两天左右，服务器关闭，根本无法访问，我必须通知服务提供商物理重启机器。

它似乎与我在日志中发现的这些SIGTERM错误有关。问题是我不知道如何解决这些问题或找到根本原因，因为我在这方面的技能缺乏。

任何人有任何想法可能会发生什么？

的Apache/2.2.3（CentOS的）

的Linux 2.6.18-028stab057.4＃1 SMP周五8月1日10点47分五十九秒MSD 2008 x86_64的

从错误日志： [Sun Nov 01 15:18:53 2009] [notice]抓到SIGTERM，关机

不完全确定这是什么原因导致我的问题，但它听起来不是一件好事。

我可以张贴如果需要更多

不应该这样去serverfault.com？ – mhaller 2009-11-02 15:34:41

我甚至不知道存在，我会在那里重新发布，谢谢。 – Tom 2009-11-02 15:51:41

汤姆，对不起，以恢复一个长期死去的线程，但最终解决了这个问题？我似乎在Apache/2.2.3（CentOS）上遇到了完全相同的问题。 CPU /内存使用最大值，然后需要硬重置。 – Wayne 2011-09-14 01:47:48

答

SIGTERM来重新启动Apache（前提是它在init进程自动重新启动安装程序）：http://httpd.apache.org/docs/2.2/stopping.html

您在日志中看到几乎肯定是有，因为你的供应商使用SIGTERM为目的的项目。如果它确实崩溃，甚至不提供静态内容，那么这听起来像某种线程/连接耗尽问题。也许是一个持有连接的DoS开放？

肯定是您的提供商调查的东西。

就是这样，由于托管解决方案的性质，我的提供商告诉我它已经脱离了他们的手。我一直告诉他们在我的结局上没有任何变化，因为这已经开始发生了，但它聋人耳语，他们只是告诉我看看日志，并聘请某人来帮助，这不是我想听到的。我会添加一些日志信息给我的OP。 – Tom 2009-11-02 15:28:13

我发现有趣的日志中的内容：“服务器在22:25:16达到MaxClients设置”以及所有访问禁止消息。看看你的访问日志，看看那段时间发生了什么。 – kdgregory 2009-11-02 15:50:16

另请注意，SIGTERM发生在09:17:58，而队列中的前一条消息是05:01:11 - 这再次表明SIGTERM是故意的。我再次查看访问日志以查看以前的活动 - 我猜测它会在05:01左右停止。 – kdgregory 2009-11-02 15:51:56

答

你问你的供应商进行调查日志信息？我认为这不是一个专用的服务器，

在它的表面上，这看起来像是一个安全异常，somone正在试图利用它/或有一个进程正在运行在一个设定的时间导致这一点，你能想想每2天在服务器上运行的任何东西？记录工具？

SIGTERM是发送到进程以请求其终止的信号。 SIGTERM的符号常量在头文件signal.h中定义。使用符号信号名称是因为信号数量可能因平台而异，但在绝大多数系统中，SIGTERM是信号＃15。

服务器是VPS，我的提供商告诉我他们不支持这种类型的东西。这几乎都在我的控制之下。如果我发布了更多的错误日志，它能帮助搞清楚他发生了什么吗？ – Tom 2009-11-02 15:12:15

它可能会发生，但到目前为止，错误日志告诉我们管理员权限告诉服务器关闭。 – LiamB 2009-11-02 15:14:24

我想，Apache会定期重新启动自己，像这样的签名来清理东西。问题可能在于它不能从该自动重启进入。 – Kzqai 2011-07-02 23:41:07

答

我在我们的L.A.M.P中有神秘的SIGTERM关机。服务器，结果是在自定义PHP模块中出现错误，这是由于版本不匹配造成的。它是通过在发生故障时查看apache访问/错误日志找到的。不要忘记打开错误日志记录。

这些错误日志是否位于/ var/logs/httpd？你还记得日志中的错误信息吗？ – Tom 2009-11-02 19:54:36

答

从this page：

我发现这个信息：

的的mod_fastcgi过程经理不在，虽然特别的患者（有改进的余地这里），并因为它必须关闭操作，发送SIGTERM到所有它负责的FastCGI应用程序。 Apache将重新启动进程管理器，它将重新启动托管应用程序（就像服务器刚刚启动一样）。 SIGTERM就是SIGTERM - 你的应用程序应该很快退出。

这对我意味着什么，如果数据库I/O或CGI脚本的其他部分无法及时响应（即数据量增长速度变慢），那么mod_fastcgi将会终止脚本......是其他人如何解释这些文档或我缺少什么......

Apache服务器不断崩溃，“发现了SIGTERM，正在关闭”
