Heroku + socket.io上的多个dynos广播 [英] Multiple dynos on Heroku + socket.io broadcasts

问题描述

我似乎遇到了一个问题，那就是我的node.js应用程序在Heroku中广播的socket.io在我有超过1个dyno时似乎不起作用。只要我将它缩放到1，它就可以很好地工作。有什么我需要知道的吗？也许有不同的方式向所有的dynos播放？如果我需要提供更多的信息或代码，请告诉我。

您必须将socket.io配置为使用非内存中会话存储，如 RedisStore 。 socket.io 文档中有详细信息，还有更多讨论< a href =https://stackoverflow.com/questions/11064826/using-socket-io-and-redis-on-heroku-with-node-js>这里。

I seem to be having an issue where socket.io broadcasts in my node.js app on Heroku don't seem to work when I have more than 1 dyno. As soon as I scale it to 1, it works perfectly. Is there anything I need to know about this? Maybe there is a different way to broadcast to all dynos? Please elt me know if I need to provide more info or code.

解决方案

If you're running on multiple dynos/servers then you have to configure socket.io to use a non-in-memory session store like the RedisStore. The socket.io documentation has details and there's more discussion here.
