为什么我的系统认为rails服务器正在运行？

Question

最近我觉得某种导轨过程悬而未决，我不确定该怎么考虑调试这个。 如果我键入'ps'并且没有运行，为什么rails咳嗽这个错误消息有关阻止该端口的另一个实例？

提供更多细节，出于某种原因，我不被允许杀死进程？ 我不了解流程的原因是什么？

Answer 1

我猜你没有检查过程。 你应该使用ps -ef或ps -aux等等。试着这样做

  ps -ef | grep rails | grep -v grep | awk '{print $2}' | xargs kill -9

UPDATE

就像我在你的图像中看到的那样，你正在使用jekyll ，它会根据变化重建网站。 最有可能的事情就是罪魁祸首。 您可以停止jekyll或在没有-w命令的情况下运行它。 如果问题仍未解决，您也可以卸载directory_watcher 。

并且，我认为你可以通过执行rails s -p 4321在随机端口中运行rails。

此外，您可以通过在ps命令中添加-9来删除该过程。 它是信号（KILL），一般来说它会优雅地和递归地杀死进程。
