為什么我的系統認為rails服務器正在運行？

Question

最近我覺得某種導軌過程懸而未決，我不確定該怎么考慮調試這個。 如果我鍵入'ps'並且沒有運行，為什么rails咳嗽這個錯誤消息有關阻止該端口的另一個實例？

/Users/jd/.rvm/gems/ruby-2.1.0/gems/eventmachine-1.0.3/lib/eventmachine.rb:526:in `start_tcp_server': no acceptor (port is in use or requires root privileges) (RuntimeError)

提供更多細節，出於某種原因，我不被允許殺死進程？ 我不了解流程的原因是什么？

Answer 1

我猜你沒有檢查過程。 你應該使用ps -ef或ps -aux等等。試着這樣做

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

UPDATE

就像我在你的圖像中看到的那樣，你正在使用jekyll ，它會根據變化重建網站。 最有可能的事情就是罪魁禍首。 您可以停止jekyll或在沒有-w命令的情況下運行它。 如果問題仍未解決，您也可以卸載directory_watcher 。

並且，我認為你可以通過執行rails s -p 4321在隨機端口中運行rails。

此外，您可以通過在ps命令中添加-9來刪除該過程。 它是信號（KILL），一般來說它會優雅地和遞歸地殺死進程。
