从linux终端运行dev_appserver.py

Question

我最近在Google Compute Engine上创建了一个虚拟机，以便在云中创建开发环境。

我有源代码并安装了Google Cloud SDK和App-Engine SDK。但是，当我尝试运行dev_appserver.py时，即使确保创建防火墙规则，我也会收到以下错误。

防火墙规则清除允许8080 TCP访问。

Answer 1

以root用户身份运行netstat -tulpn以查看它们是否是在端口8080上运行的进程。键入fuser 8080 / tcp以获取在端口8080上运行的进程的PID并终止该端口或仅使用参数-k和fuser命令，即fuser -k 8080 / tcp来终止该进程。它适用于我。
