nginx-passenger 關閉，安裝雙重檢查（更新）

tag-icon • tag-icon nginx centos6 ruby-on-rails phusion-passenger
nginx-passenger 關閉，安裝雙重檢查（更新）

我剛剛在 Bluehost 設定了一個 vps。 Centos 6。

[ ... ]: Signal received. Gracefully shutting down... (send signal 2 more time(s) to force shutdown)

我多次重新啟動 nginx，檢查其運行級別，用一對正在運行的應用程式進行測試......但我無法阻止 nginx 繼續關閉。

於是，我到處尋找。在 StackOverflow乘客作者建議按照說明重新安裝，我做了（兩次）但沒有更好的結果。

進一步挖掘發現了這個類似的問題還沒有好的答案。

進一步挖掘，我發現了一個解決方案在伺服器故障中，與 Rails 應用程式相關，就像我的例子一樣。但我找不到rubber-passenger_nginx.yml，因為我沒有使用rubber。

關於編譯所有最新版本，我仔細檢查了 nginx、passenger（在伺服器上使用 yum 安裝並作為 gem 包含在應用程式中）、rvm、ruby、我的 Rails 應用程式設定。一切都好。但是 nginx 停止了。請幫忙...

感謝@drookie 的評論。我收集了一些信息，並試圖學習如何在 Linux 中追蹤 SIGINT。這是最新安裝相同錯誤的軌跡，安裝的第一個錯誤。我得到了大約 100 個 GET /whm-server-status HTTP/1.0 的 404（為什麼 nginx 要求 apache？），然後：

我發現問題不是nginx或passenger的問題。伺服器已安裝 WHM。因此，控制面板的安全性正在改變我在 bash 中發出的命令。另外，安裝很舊。更新whm並正確使用後，nginx關閉的問題就解決了。 @drookie，你是對的，不是一個簡單的守護進程，而是整個whm造成的。謝謝。
