Javascript 如何正确停止节点API群集服务器？ 我只是学习在我的膝关节炎+类型脚本API中使用集群。我找到了一篇博客文章，并从中获取了参考资料 // server.ts import {app} from './app' // Koa export function server() { const http = app.listen(8000, async () => { console.info(`Listening at 8000`) }) return http }

问题是，当我停止使用

Ctrl+c

时，我得到了这个结果：

看看这里的建议。我也在寻找一种对任何形式的进程终止进行清理的方法……基本上，你应该只在清理为真的情况下进行终止。我还建议你找一个进程管理器。例如，看看PM2，它允许你在集群中轻松启动应用程序并管理不同的工作er为您处理！
它真的很致命。非常感谢！还有一个问题，我能用它完全取代我的船载优雅关机功能吗？对于PM2，我以前用过它。但现在我和Docker在一起，我看到人们不建议在Docker内运行PM2。您会在Docker内使用PM2吗？很抱歉，很难说……永远不要运行这是pm2和docker的问题。但也许还有其他选择？至于你是否可以替换它的问题……在清理过程中，你应该能够调用任何你需要的东西来很好地清理。很难说到底可以移除什么。实验？非常感谢。我会尝试。：）没问题！对不起，我帮不了你了
