尝试用 Knife 创建 EC2 服务器时出现 SSLError

Question

我正在尝试使用 knife 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]

我相当确定我使用 openssl 支持正确编译了 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 跑 Knife 。这具有相同的结果，但有一条不太有用的错误消息:“错误:Excon::Errors::SocketError:主机名与服务器证书不匹配(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:

为了使用 knife 成功创建 EC2 实例，我还需要配置什么吗？

Answer 1

在我的 knife.rb 配置文件中，我有这一行:

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

这在过去的某个时候有效，但当前正确的设置是:

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
