Rails精简服务器未找到PID

Question

我在Ubuntu上运行Rails，使用的是Nginx web服务器和5个瘦应用服务器。

每天一次，系统变得非常慢，有时会挂断。

我不确定是否是瘦服务器，但当我在挂起时停止服务器时，我会得到：

Can't stop process, no PID found in tmp/pids/thin.3000.pid

以下是显示精简启动和停止的日志：

bitnami@linux:/opt/bitnami$ thin -C projects/myapp/current/config/thin.yml start

有时它会发现PIDS，但有时它不会。这是什么意思？

谢谢!

我也有同样令人恼火的问题

我发现，如果服务器在启动时崩溃，则会创建pid文件，但该文件中没有pid。尝试对服务器./logs/thin.3001.log的日志文件进行cat，并查找错误。您也可以尝试通过以下方式手动启动服务器

rails s -p 3000

并查看是否抛出了任何错误。

祝好运
