无法启动 Rails 开发，Cloud 9

Question

我曾尝试使用来自云 9 的这篇文章杀死我的 rails 服务器。

我正在使用 gem thin，每次尝试运行云服务器命令时，我都会收到此错误

rails s -b $IP -p $PORT
=> Booting Thin
=> Rails 4.2.6 application starting in development on http://0.0.0.0:8080
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server

Answer 1

此错误表明，8080 端口已被使用，您可能需要为您的应用程序使用不同的端口

更新:

尝试终止现有进程。使用此命令 ps -ef | grep thin 查找端口号，然后将其杀死 kill -9 <port>。立即试用运行您的应用。

Answer 2

好像是8080端口被占用了，要使用端口查找PID，运行:

netstat -tulpn | grep :8080

那你可以kill -9 <PID>
