Apache服務器不斷崩潰，「發現了SIGTERM，正在關閉」

這種情況剛剛發生在三週前。我的網站內容沒有改變，它只是一個使用MySQL作爲後端的phpBB論壇。Apache服務器不斷崩潰，「發現了SIGTERM，正在關閉」

一年來沒有任何變化，但最近，每兩天左右，服務器關閉，根本無法訪問，我必須通知服務提供商物理重啓機器。

它似乎與我在日誌中發現的這些SIGTERM錯誤有關。問題是我不知道如何解決這些問題或找到根本原因，因爲我在這方面的技能缺乏。

任何人有任何想法可能會發生什麼？

的Apache/2.2.3（CentOS的）

的Linux 2.6.18-028stab057.4＃1 SMP週五8月1日10點47分五十九秒MSD 2008 x86_64的

從錯誤日誌： [Sun Nov 01 15:18:53 2009] [notice]抓到SIGTERM，關機

不完全確定這是什麼原因導致我的問題，但它聽起來不是一件好事。

我可以張貼如果需要更多

不應該這樣去serverfault.com？ – mhaller 2009-11-02 15:34:41

我甚至不知道存在，我會在那裏重新發布，謝謝。 – Tom 2009-11-02 15:51:41

湯姆，對不起，以恢復一個長期死去的線程，但最終解決了這個問題？我似乎在Apache/2.2.3（CentOS）上遇到了完全相同的問題。 CPU /內存使用最大值，然後需要硬重置。 – Wayne 2011-09-14 01:47:48

SIGTERM來重新啓動Apache（前提是它在init進程自動重新啓動安裝程序）：http://httpd.apache.org/docs/2.2/stopping.html

您在日誌中看到幾乎肯定是有，因爲你的供應商使用SIGTERM爲目的的項目。如果它確實崩潰，甚至不提供靜態內容，那麼這聽起來像某種線程/連接耗盡問題。也許是一個持有連接的DoS開放？

肯定是您的提供商調查的東西。

就是這樣，由於託管解決方案的性質，我的提供商告訴我它已經脫離了他們的手。我一直告訴他們在我的結局上沒有任何變化，因爲這已經開始發生了，但它聾人耳語，他們只是告訴我看看日誌，並聘請某人來幫助，這不是我想聽到的。我會添加一些日誌信息給我的OP。 – Tom 2009-11-02 15:28:13

我發現有趣的日誌中的內容：「服務器在22:25:16達到MaxClients設置」以及所有訪問禁止消息。看看你的訪問日誌，看看那段時間發生了什麼。 – kdgregory 2009-11-02 15:50:16

另請注意，SIGTERM發生在09:17:58，而隊列中的前一條消息是05:01:11 - 這再次表明SIGTERM是故意的。我再次查看訪問日誌以查看以前的活動 - 我猜測它會在05:01左右停止。 – kdgregory 2009-11-02 15:51:56

你問你的供應商進行調查日誌信息？我認爲這不是一個專用的服務器，

在它的表面上，這看起來像是一個安全異常，somone正在試圖利用它/或有一個進程正在運行在一個設定的時間導致這一點，你能想想每2天在服務器上運行的任何東西？記錄工具？

SIGTERM是發送到進程以請求其終止的信號。 SIGTERM的符號常量在頭文件signal.h中定義。使用符號信號名稱是因爲信號數量可能因平臺而異，但在絕大多數系統中，SIGTERM是信號＃15。

服務器是VPS，我的提供商告訴我他們不支持這種類型的東西。這幾乎都在我的控制之下。如果我發佈了更多的錯誤日誌，它能幫助搞清楚他發生了什麼嗎？ – Tom 2009-11-02 15:12:15

它可能會發生，但到目前爲止，錯誤日誌告訴我們管理員權限告訴服務器關閉。 – LiamB 2009-11-02 15:14:24

我想，Apache會定期重新啓動自己，像這樣的簽名來清理東西。問題可能在於它不能從該自動重啓進入。 – Kzqai 2011-07-02 23:41:07

我在我們的L.A.M.P中有神祕的SIGTERM關機。服務器，結果是在自定義PHP模塊中出現錯誤，這是由於版本不匹配造成的。它是通過在發生故障時查看apache訪問/錯誤日誌找到的。不要忘記打開錯誤日誌記錄。

這些錯誤日誌是否位於/ var/logs/httpd？你還記得日誌中的錯誤信息嗎？ – Tom 2009-11-02 19:54:36

從this page：

我發現這個信息：

的的mod_fastcgi過程經理不在，雖然特別的患者（有改進的餘地這裏），並因爲它必須關閉操作，發送SIGTERM到所有它負責的FastCGI應用程序。 Apache將重新啓動進程管理器，它將重新啓動託管應用程序（就像服務器剛剛啓動一樣）。 SIGTERM就是SIGTERM - 你的應用程序應該很快退出。

這對我意味着什麼，如果數據庫I/O或CGI腳本的其他部分無法及時響應（即數據量增長速度變慢），那麼mod_fastcgi將會終止腳本......是其他人如何解釋這些文檔或我缺少什麼......
