我在 RoR 中有应用程序，我在 apache2 上对其进行测试以上传 > 1 GB 的文件，它正在工作。但我必须使用 nginx。在 nginx 服务器上 100% 上传后出现此错误：

2012/11/09 17:17:01 [错误] 1436#0: *12 上游过早关闭连接，同时从上游读取响应标头，客户端：134.19.136.32，服务器：my_domain，请求：“POST /attachments HTTP/1.1” ，上游：“http://unix:/tmp-sock/unicorn.my_domain.sock:/attachments”，主机：“my_domain”，引用者：“http://my_domain/”

我认为问题出在独角兽设置上，但我不知道具体在哪里。顺便说一句：一切都只在 Firefox 中有效。

我的配置文件：

将大文件直接发送到您的 Rails 应用程序并不是上传大文件的好方法。您可以使用 nginx上传模块来处理使用 unicorn+nginx 的大文件上传。这样，nginx 实际上处理文件上传，而不是将整个文件作为多部分形式的数据传递给 rails，而是将由 nginx 上传的本地文件路径发送到独角兽 rails 服务器，rails 所做的就是将文件从操作系统的 tmp 路径到您定义的路径。在这里，我配置了 nginx 和 rails 以使用 nginx 上传模块进行上传作业。现在有更好的处理上传的解决方案，例如TUS协议。

keepalive_timeout我通过增加Nginx 配置解决了这个问题。也许这不是一个合适的解决方案，或者您可以根据位置和请求类型增加它。对于 Firefox 部分，Firefox 等待响应的时间比 Chrome 长。
