Heroku node.js应用程序在heroku打开时崩溃

Question

我已经按照“Heroku开始使用node.js”教程，直到我尝试'heroku open'时才出现问题。 Heroku的日志如下：

的问题是与我没有经验的Redis。

Redis Heroku作为插件安装，当我的本地机器运行npm start时，一切正常。

有没有人遇到过这个或有任何想法？

Answer 1

您可能有一个本地运行的redis服务器，但是您的Heroku实例无法连接到本地的redis实例，并且如果您在Heroku运行中使用相同的配置，它将寻找在同一端点上的东西（我猜127.0.0.1端口3000或其他）。

在Redis的到去，你可以得到一个免费/纳米计划，你可以测试一下。 http://redistogo.com/ 只需连接远程。 这是通过Heroku进行配置的替代方案，我想我在几个月前验证了这种方法的有效性。它仍然应该。

您可以测试的Heroku更接近其部署的环境条件下的局部应用，请使用~~ foreman start ~~现在heroku local https://devcenter.heroku.com/articles/heroku-local， 并检查了这对process https://devcenter.heroku.com/articles/procfile
