nginx-passenger 关闭，安装双重检查（已更新）

nginx-passenger 关闭，安装双重检查（已更新）

我刚刚在 Bluehost 设置了一个 vps。Centos 6。两天来我的 nginx 服务器关闭并记录了以下内容：

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

我多次重新启动 nginx，检查它的运行级别，用一对正在运行的应用程序进行测试......但我无法阻止 nginx 继续关闭。

因此，我到处搜索。在 StackOverflow乘客作者建议按照说明重新安装，我这样做了两次，但没有更好的结果。

进一步挖掘发现类似问题但目前还没有好的答案。

进一步挖掘后，我发现了一个解决方案在 serverfault 中，与 rails 应用程序相关，就像我的情况一样。但我找不到 rubber-passenger_nginx.yml，因为我没有使用 rubber。

关于是否要编译所有最新版本，我仔细检查了 nginx、passenger（使用 yum 安装在服务器上并作为 gem 包含在应用程序中）、rvm、ruby 和我的 rails 应用程序配置。一切正常。但 nginx 停止了。请帮忙...

感谢 @drookie 的评论。我收集了一些信息，并试图学习如何在 Linux 中跟踪 SIGINT。这是最新安装中相同错误的轨迹，安装的第一个错误。我得到了 GET /whm-server-status HTTP/1.0 的 100 个 404（为什么 nginx 要求 apache？）然后：

我找到了问题，它不是 nginx 或 Passenger。服务器安装了 WHM。因此，控制面板的安全性正在更改我在 bash 中给出的命令。此外，安装是旧的。一旦 whm 更新并正确使用，nginx 关闭的问题就解决了。@drookie，你是对的，不是一个简单的守护进程，而是整个 whm 导致了它。谢谢。
