Question

我试图将我的应用程序启动到Heroku上，并且在几个地方挂断了。我已经使用＆＃39; node.js＆＃39;设置了应用。提供的流程，并使用插件Redis Cloud，＆＃39;但它正在挂断。

使用heroku logs --tail我收到一长串错误消息，但大多数都是来自我没有写过或触摸过的node_modules。

类似于此的错误发生了几（3）次，但它的一般结构是：

还有一些其他错误可能会或可能不会被捆绑，但它们含糊不清（code=H10似乎只是表明存在问题......而不是它是什么。）

那么，这是否足以确定这是为什么/应用程序挂断的原因？

Answer 1

鉴于此：

Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED

建议您的代码尝试建立与本地Redis服务器的连接。在Heroku上使用Redis Cloud时，您需要打开与Redis数据库的连接，其端点和密码存储在REDISCLOUD_URL env var。

中

将节点/ redis / socket应用程序启动到heroku时出现问题
