在分阶段启动Rails应用程序时出错-Unicorn

debugcn 发表于 Dev

克里斯蒂安

因此，我刚刚将Rails 4应用程序部署到了运行Nginx + Unicorn的AWS EC2实例。我认为一切都在Unicorn方面运行良好，因为请求正在触及Rails应用程序，但是我遇到了这个奇怪的500错误，无法确定它来自何处。

这就是我从中学到的东西staging.log。我不知道发生了什么，任何帮助都将是很大的。

我不是Ruby专家。但是在错误日志中像这样的回溯转储也使我感到疯狂。关键是查看最上面的几行：

I, [2014-05-25T05:11:29.460247 #21589]  INFO -- : Started GET "/" for <ip> at 2014-05-25 05:11:29 +0000

TypeError (no implicit conversion of Array into String):

500错误表示存在内部服务器错误。这意味着您的代码中有什么问题（无论是PHP，Perl还是Ruby）都在完全杀死服务器。我在这里看到的关键是：

TypeError (no implicit conversion of Array into String):

在Ruby代码中的某个地方，您试图将数组分配为字符串。这就是杀死整个过程的原因。在哪里？不确定是否查看日志。但这是整个事情失败的关键。转储的其余部分基本上是对支持您的应用程序的所有已加载项目（库等）的报告。
