python - 从 Linux 终端运行 dev_appserver.py

Question

我最近在 Google Compute Engine 上启动了一个虚拟机，目的是在云中创建一个开发环境。

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，即使确保创建了防火墙规则，我也会收到以下错误。

防火墙规则明确允许8080 TCP访问。

Answer 1

以 root 用户身份运行 netstat -tulpn 以查看其是否是在端口 8080 上运行的进程。键入 fusionr 8080/tcp 以获取在端口 8080 上运行的进程的 PID 并终止该端口，或者只需将参数 -k 与 fusionr 命令一起使用，即 fusione -k 8080/tcp 来终止该进程。它对我来说工作得很好。
