什么可能导致这个heroku崩溃？错误代码= H10

时间：2017-09-08 02:30:56

标签： express heroku sequelize.js auth0

我查看了过去关于这个问题的帖子，很多人建议heroku重启，或者重启dynos，或者确保使用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。

有人有任何建议吗？谢谢！

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SQL服务器。

从它的外观来看，你似乎试图连接127.0.0.1:3306，这将无法正常工作。 127.0.0.1或localhost是您当地的IP。

您需要设置/连接到https://devcenter.heroku.com/articles/error-codes#h10-app-crashed插件或使用外部SQL服务，例如Heroku's Postgres。
