尝试使用刀创建 EC2 服务器时出现 SSLError

Question

我正在尝试使用刀创建和配置一个新的 EC2 实例，但一直遇到 SSL 错误：

$bundle exec knife ec2 server create
ERROR: Excon::Errors::SocketError: hostname "ec2.us-east-1b.amazonaws.com" does not match the server certificate (OpenSSL::SSL::SSLError)

我正在使用 ruby​​ 2.0.0p0 从 mac (10.7) 运行它：

$ruby -v
ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin11.4.2]

我相当肯定我正确编译了带有 openssl 支持的 ruby​​。从 irb 运行 require 'openssl' 返回 true。我正在使用通过自制软件安装的 OpenSSL 1.0.1e。

我还尝试使用 ruby​​ 1.9.3-p194 运行刀。这具有相同的结果，但有用的错误消息略少：“错误：Excon::Errors::SocketError: hostname does not match the server certificate (OpenSSL::SSL::SSLError)”。这种差异是此拉取请求的结果，它改进了错误消息：https://github.com/ruby/ruby/pull/122。

curl 的以下输出可能是相关的：

$curl -v https://ec2.us-east-1b.amazonaws.com

*   Trying 67.215.65.132... connected

为了用刀成功创建 EC2 实例，我还需要配置其他什么吗？

在我的knife.rb 配置文件中，我有这行：

knife[:region] = 'us-east-1b'

这在过去的某个时候有效，但正确的当前设置是：

knife[:region] = 'us-east-1'

删除“b”可解决 SSL 主机名错误：

$curl -v https://ec2.us-east-1.amazonaws.com
* About to connect() to ec2.us-east-1.amazonaws.com port 443 (#0)
*   Trying 205.251.242.7... connected

当你在你的 mac book 上安装 chef-client 时，它会自动安装刀和依赖库，你不必手动安装。您不必使用 bundle exec 运行，只需键入knife ec2 server create，您将得到以下输出

** EC2 COMMANDS **
knife ec2 server list (options)
knife ec2 server delete SERVER [SERVER] (options)
knife ec2 server create (options)
knife ec2 instance data (options)
knife ec2 flavor list (options)

如果你得到这个输出，那么你的刀工作正常。还要确保你的knife.rb 配置正确，如果你有任何问题请告诉我。
