业务上需要用到分布式文件服务，选择了minio作为文件服务的组件，搭建好服务后使用IP+端口号（http://xx.xx.xx.xx:9001）的形式访问在所有环境下都没有问题。
上线部署时出于正规和安全考虑使用了nginx设置域名代理minio服务（http://www.xxx.com:9001)，管理端登录和查看文件都没问题，但是上传文件即报以下错误，期间还发生过时好时坏的情况。
io.minio.errors.ErrorResponseException: The request signature we calculated does not match the signature you provided. Check your key and signing method.

尝试了各种形式只要加上端口号就不行，由于不影响正常使用没有深入调查，最终选择给minio服务分配一个独立的域名并使用80端口代理的方案得以解决。
# Minio配置

我想安装一个带有一些身份验证的私有(private)Rubygem服务器。我希望能够使用公共(public)Ubuntu服务器托管内部gem。我读到了http://docs.rubygems.org/read/chapter/18.但是那个没有身份验证-如我所见。然后我读到了https://github.com/cwninja/geminabox.但是当我使用基本身份验证(他们在他们的Wiki中有)时，它会提示从我的服务器获取源。所以。如何制作带有身份验证的私有(private)Rubygem服务器？这是不可能的吗？谢谢。编辑:Geminabox问题。我尝试“捆绑”以安装新的gem..

我有一个包含模块的模型。我想在模块中覆盖模型的访问器方法。例如:classBlah这显然行不通。有什么想法可以实现吗？ 最佳答案 您的代码看起来是正确的。我们正在毫无困难地使用这个确切的模式。如果我没记错的话，Rails使用#method_missing作为属性setter，因此您的模块将优先，阻止ActiveRecord的setter。如果您正在使用ActiveSupport::Concern(参见thisblogpost)，那么您的实例方法需要进入一个特殊的模块:classBlah
