Question

我已经为heroku部署了一个django应用程序，它使用芹菜来执行长时间运行的任务。出于性能原因（时间和内存），我产生了两个具有不同并发设置的工作程序并路由任务。它在我的本地环境中运行良好，但工作人员立即在heroku上崩溃。

这就是我从日志中得到的全部内容......我是否需要为heroku设置一些特殊设置，或celery multi不能在单个dyno上工作（不再）了？我用谷歌提供了最明显的关键词，但没有看到答案。

非常感谢任何帮助或提示！

Answer 1

Celery Multi将节点作为守护进程启动，然后立即退出。进程监视器看到退出代码并认为程序已崩溃，因此它重新启动了dyno。
