我一直通过S3Fox 与 Amazon S3 进行交互，但我似乎无法删除我的存储桶。我选择了一个存储桶，点击删除，在弹出窗口中确认删除，然后......没有任何反应。我应该使用其他工具吗？
【问题讨论】：
s3cmd 的最新版本有 --recursive
例如，
~/$ s3cmd rb --recursive s3://bucketwithfiles
【讨论】：
终于可以使用新的生命周期（过期）规则功能一次性删除所有文件。您甚至可以从 AWS 控制台执行此操作。
只需在 AWS 控制台中右键单击存储桶名称，选择“属性”，然后在页面底部的选项卡行中选择“生命周期”和“添加规则”。创建生命周期规则，将“Prefix”字段设置为空白（空白表示存储桶中的所有文件，或者您可以将其设置为“a”以删除名称以“a”开头的所有文件）。将“天”字段设置为“1”。而已。完毕。假设文件超过一天，它们都应该被删除，那么您可以删除存储桶。
我只是第一次尝试这个，所以我仍在等待查看文件被删除的速度（它不是即时的，但大概应该在 24 小时内发生）以及我是否需要为一个删除命令或5000 万条删除命令……祈祷！
【讨论】：
aws cli 一个命令可以递归删除所有文件：aws s3 rm s3://bucket/folder/ --recursive
亚马逊最近添加了一项新功能“多对象删除”，该功能允许通过单个 API 请求一次删除多达 1,000 个对象。这应该可以简化从存储桶中删除大量文件的过程。
新功能的文档可在此处获得：http://docs.amazonwebservices.com/AmazonS3/latest/dev/DeletingMultipleObjects.html
【讨论】：
我是 Bucket Explorer 团队的开发团队成员之一，我们将根据用户的选择提供不同的选项来删除 Bucket... 1) 快速删除 - 此选项将以 1000 个为单位从存储桶中删除您的数据。 2) 永久删除-此选项将删除队列中的对象。
【讨论】：
如果您安装了ruby（和rubygems），请安装aws-s3 gem with
gem install aws-s3
或
sudo gem install aws-s3
创建文件delete_bucket.rb:
require "rubygems" # optional
require "aws/s3"
AWS::S3::Base.establish_connection!(
:access_key_id => 'access_key_id',
:secret_access_key => 'secret_access_key')
AWS::S3::Bucket.delete("bucket_name", :force => true)
并运行它：
ruby delete_bucket.rb
由于Bucket#delete为我返回了很多超时异常，我已经扩展了脚本：
require "rubygems" # optional
require "aws/s3"
AWS::S3::Base.establish_connection!(
:access_key_id => 'access_key_id',
:secret_access_key => 'secret_access_key')
while AWS::S3::Bucket.find("bucket_name")
begin
AWS::S3::Bucket.delete("bucket_name", :force => true)
rescue
end
end
【讨论】：
如果您使用亚马逊的控制台，并且需要一次性清除存储桶：您可以浏览到存储桶，然后选择顶部键，然后滚动到底部，然后按键盘上的 shift，然后单击底部一。它将在两者之间选择所有，然后您可以右键单击并删除。
【讨论】：
使用亚马逊网络管理控制台。使用谷歌浏览器提高速度。删除对象的速度比 firefox 快得多（大约快 10 倍）。有 60 000 个对象要删除。
【讨论】：
我已经实现了 bucket-destroy，这是一个多线程实用程序，可以执行删除存储桶所需的一切操作。我处理非空存储桶，以及启用版本的存储桶键。
您可以在此处阅读博文 http://bytecoded.blogspot.com/2011/01/recursive-delete-utility-for-version.html 和此处的说明 http://code.google.com/p/bucket-destroy/
我已经成功地删除了一个存储桶，该存储桶在键名、版本化键和 DeleteMarker 键中包含双“//”。目前我在一个包含 ~40,000,000 的存储桶上运行它，到目前为止，我已经能够在 m1.large 上的几个小时内删除 1,200,000。请注意，该实用程序是多线程的，但（尚未）实现改组（将水平缩放，在多台机器上启动该实用程序）。
【讨论】：
可用于避免此问题的一种技术是将所有对象放在存储桶中的“文件夹”中，让您只需删除文件夹，然后继续删除存储桶。此外，http://s3tools.org 提供的 s3cmd 工具可用于删除其中包含文件的存储桶：
s3cmd rb --force s3://bucket-name
【讨论】：
这是一个难题。我的解决方案是http://stuff.mit.edu/~jik/software/delete-s3-bucket.pl.txt。它在顶部的评论中描述了我确定可能出错的所有事情。这是脚本的当前版本（如果我更改它，我会在 URL 上放一个新版本，但可能不在此处）。

# Deleting an Amazon S3 bucket is hard.
#
# * You can't delete the bucket unless it is empty.
#
# * There is no API for telling Amazon to empty the bucket, so you have to
# delete all of the objects one by one yourself.
#
# * If you've recently added a lot of large objects to the bucket, then they
# may not all be visible yet on all S3 servers. This means that even after the
# server you're talking to thinks all the objects are all deleted and lets you
# delete the bucket, additional objects can continue to propagate around the S3
# server network. If you then recreate the bucket with the same name, those
# additional objects will magically appear in it!
#
# It is not clear to me whether the bucket delete will eventually propagate to
# all of the S3 servers and cause all the objects in the bucket to go away, but
# I suspect it won't. I also suspect that you may end up continuing to be
# charged for these phantom objects even though the bucket they're in is no
# longer even visible in your S3 account.
#
# * If there's a CR, LF, or CRLF in an object name, then it's sent just that
# way in the XML that gets sent from the S3 server to the client when the
# client asks for a list of objects in the bucket. Unfortunately, the XML
# parser on the client will probably convert it to the local line ending
# character, and if it's different from the character that's actually in the
# object name, you then won't be able to delete it. Ugh! This is a bug in the
# S3 protocol; it should be enclosing the object names in CDATA tags or
# something to protect them from being munged by the XML parser.
#
# Note that this bug even affects the AWS Web Console provided by Amazon!
#
# * If you've got a whole lot of objects and you serialize the delete process,
# it'll take a long, long time to delete them all.

Specify --processes to indicate how many deletes to perform in
parallel. You're limited by RAM (to hold the parallel threads) and
bandwidth for the S3 delete requests.
Specify --wait to indicate seconds to require the bucket to be verified
empty. This is necessary if you create a huge number of objects and then
try to delete the bucket before they've all propagated to all the S3
servers (I've seen a huge backlog of newly created objects take *hours* to
propagate everywhere). See the comment at the top of the script for more
information about this issue.

这是我使用的。只是简单的 ruby 代码。
case bucket.size
when 0
puts "Nothing left to delete"
when 1..1000
bucket.objects.each do |item|
item.delete
puts "Deleting - #{bucket.size} left"
end
end

更无耻的插件：当我不得不删除 250,000 个项目时，我厌倦了等待单个 HTTP 删除请求，所以我编写了一个 Ruby 脚本，它可以多线程执行并在很短的时间内完成：

由于线程的处理方式，这在 Ruby 1.9 中运行得更快。

我用 Python 编写了一个脚本，它成功地删除了我的 9000 个对象。请参阅此页面：

请记住，S3 存储桶需要为空才能删除。好消息是大多数 3rd 方工具可以自动执行此过程。如果您在使用 S3Fox 时遇到问题，我建议您尝试用于 GUI 的 S3FM 或用于命令行的 S3Sync。亚马逊有一篇很棒的文章描述了how to use S3Sync。设置好变量后，关键命令是
./s3cmd.rb deleteall <your bucket name>
删除包含大量单个文件的存储桶往往会使许多 S3 工具崩溃，因为它们会尝试显示目录中所有文件的列表。你需要想办法批量删除。我为此目的找到的最好的 GUI 工具是 Bucket Explorer。它以 1000 个文件块删除 S3 存储桶中的文件，并且在尝试打开 s3Fox 和 S3FM 等大型存储桶时不会崩溃。
我还找到了一些可用于此目的的脚本。我还没有尝试过这些脚本，但它们看起来很简单。

使用 s3cmd： 创建一个新的空目录 s3cmd 同步 --delete-removed empty_directory s3://yourbucket
【讨论】：
SpaceBlock 还使删除 s3 存储桶变得简单 - 右键单击存储桶，删除，在传输视图中等待作业完成，完成。
这是我维护的免费和开源的windows s3前端，所以不要脸的插件警报等等。
【讨论】：
首先删除存储桶中的所有对象。然后您可以删除存储桶本身。
显然，无法删除其中包含对象的存储桶，S3Fox 不会为您执行此操作。
我自己也遇到过其他关于 S3Fox 的小问题，比如这个，现在使用基于 Java 的工具，jets3t，它更适用于错误情况。肯定还有其他人。
【讨论】：
我总是最终使用他们的 C# API 和小脚本来执行此操作。我不确定为什么 S3Fox 不能做到这一点，但目前该功能似乎已被破坏。不过，我确信许多其他 S3 工具也可以做到这一点。
