我使用 Nginx Web 服务器和 5 个瘦应用服务器在 Ubuntu 上运行 Rails。
系统每天都会变得非常慢，有时会挂起。
我不确定是否是瘦服务器，但是当我在挂起时停止服务器时，我得到:
Can't stop process, no PID found in tmp/pids/thin.3000.pid
这是显示精简启动和停止的日志:

有时它会找到 PIDS，有时却找不到。这是什么意思？
谢谢!
最佳答案
我遇到了完全相同的恼人问题
我发现，如果服务器在启动时崩溃，则会创建 pid 文件，但文件中没有 pid。尝试检查服务器的日志文件 ./logs/thin.3001.log 并查找错误。您也可以尝试通过
手动启动服务器rails s -p 3000
并查看是否抛出任何错误。
祝你好运

关于ruby-on-rails - Rails 瘦服务器未找到 PID，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/17073371/
