django - 对静态文件使用s3，boto，django-storage时，对等方重置连接

Question

我试图切换为使用亚马逊S3来为django项目托管我们的静态文件。我正在使用django，boto，django-storage和django-compressor。当我在开发服务器上运行collect static时，出现错误

socket.error: [Errno 104] Connection reset by peer 

我所有静态文件的大小为74MB，这似乎并不太大。有没有人看过这个，或者有任何调试提示？

这是完整的痕迹。

更新:我没有如何调试此错误的答案，但此后才停止发生，这使我认为它可能与S3上的某些内容有关。

Answer 1

tl; dr

如果您的存储桶不在默认区域中，则需要告诉Boto要连接到哪个区域，例如如果您的存储桶位于us-west-2中，则需要在settings.py中添加以下行:

 AWS_S3_HOST = 's3-us-west-2.amazonaws.com'

详细说明:

这不是权限问题，您不应将存储桶权限设置为“已认证的用户”。

如果您在默认区域以外的区域中创建存储桶，则会发生此问题(在我的情况下，我使用的是us-west-2)。

如果您不使用默认区域并且不告诉boto存储桶位于哪个区域，boto将连接到默认区域，并且S3将以307重定向回复到存储桶所属的区域。

不幸的是，由于boto中的这个错误:

https://github.com/boto/boto/issues/2207

如果307回复在boto完成上传文件之前到达，则boto将看不到重定向，并将继续上传到默认区域。
最终，S3关闭套接字，导致“对等方重置连接”。

这是一种竞争条件，它取决于要上传的对象的大小和Internet连接的速度，这说明了为什么它随机发生。

OP一段时间后停止看到错误的可能原因有两个:

- he later created a new bucket in the default region and the problem went away by itself. 
- he started uploading only small files, which are fast enough to be fully uploaded by the time S3 replies with 307
