express - 什么可能导致此heroku崩溃？错误代码=H10

标签 express heroku sequelize.js auth0

我查看了过去关于这个问题的帖子，许多人建议重新启动 heroku，或重新启动 dynos，或确保使用 var PORT = process.env.PORT || 3000. 我已经做了所有这些，但我的应用程序仍然崩溃。该应用程序使用 node/express sequelize/auth0 运行。

有没有人有什么建议？谢谢!

最佳答案

https://devcenter.heroku.com/articles/error-codes#h10-app-crashed

您的日志清楚地告诉您崩溃的原因:

2017-09-08T02:11:37.293030+00:00 app[web.1]: Unhandled rejection . 
SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:3306

您无法连接到您的 SQL 服务器。

从它的外观来看，您似乎正在尝试连接到 127.0.0.1:3306 ，但它不起作用。 127.0.0.1 或 localhost 是您的本地 IP。

您需要设置/连接到 Heroku's Postgres 插件或使用外部 SQL 服务，例如 Amazon RDS 。
