当使用s3,boto,django-storage作为静态文件时,由对等方重置连接

Question

我正在尝试切换到使用amazon s3来托管我们的django项目的静态文件.我正在使用django,boto,django-storage和django-compressor.当我在我的开发服务器上运行collect static时,我收到了错误

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

我所有静态文件的大小都是74MB,看起来不算太大.有没有人见过这个,或者有任何调试技巧？

这是完整的痕迹.

更新:我没有如何调试此错误的答案,但后来这个停止发生,这让我觉得它可能与S3上的某些事情有关.

TL;博士

如果您的存储桶不在默认区域,您需要告诉boto要连接的区域,例如,如果您的存储桶位于us-west-2,则需要将以下行添加到settings.py:

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

很长的解释:

这不是权限问题,您不应将存储桶权限设置为"经过身份验证的用户".

如果您在一个非默认区域(在我的情况下,我使用us-west-2)中创建您的存储桶,则会出现此问题.

如果您不使用默认区域,并且未告知boto您的存储区所在的区域,则boto将连接到默认区域,S3将使用307重定向进行回复,以指向存储区所属的区域.

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,boto将不会看到重定向并继续上传到默认区域.最终S3关闭套接字,导致"由对等方重置连接".

这是一种竞争条件,取决于上传对象的大小和互联网连接的速度,这解释了为什么它会随机发生.

一段时间后,OP停止看到错误的原因有两个:

- 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

Answer 2

这是第一次创建新存储桶时会出现的问题，您必须等待几小时或几分钟才能开始上传。我不知道为什么 s3 会这样。为了证明尝试创建一个新存储桶，将您的 django 存储指向它，当您尝试从 django 项目上传任何内容时，您会看到它显示连接对等重置，但等待几个小时或几分钟再试一次它会起作用。重复同样的步骤，看看。

Answer 3

您必须将存储桶权限设置为Authenticated Users列表+上传/删除或者您可以在亚马逊的 IAM 部分创建特定用户并仅为该特定用户设置访问权限
