OpenStack 博客 关于 OpenStack 的所有文字记录。

一年多来，我一直在忠实地执行 OpenStack 的安装，编写笔记和文档，了解如何操作该软件，并最重要的是，报告我遇到的任何错误。目的是调查 OpenStack 是否作为可行的云托管平台。问题是，我一直在忠实地执行 OpenStack 的安装一年多，跟踪版本之间的变化（以及跟踪版本内的变化），虽然该项目正在取得很大的进展，但从潜在的最终用户和业务客户的角度来看，在拥有既能兑现承诺又能向我的雇主展示的东西方面，耐心正在逐渐消失。

几周前，我将此内容发布到 OpenStack 邮件列表中

Dear all,
I had my first sleepless night last night after a conversation I had in
work regarding an OpenStack installation.  We are a planning an OpenStack
install but I've failed to demonstrate OpenStack running in our environment
and yet packages are now being tagged up with RC.  As big a supporter as I
am, I'm struggling with the justifications when I have nothing tangible to
show.  The real questions are being posed to me on why we're looking at
OpenStack and not CloudStack or Eucalyptus - they have installations that
we can turn to.  I was hoping Essex would help answer these questions
relatively simply, but the opposite has happened - I am struggling to get
OpenStack Essex working under Ubuntu - 11.10 and 12.04.  There are a few
issues I am hoping the community can address...

我已精疲力竭，几乎要放弃了——一年时间，留下了许多伤痕。
然而，几个小时内，情况开始发生变化。人们一个个地回应我的请求。这种回应简直非同寻常。个人贡献者、核心开发者、业务驱动者都出来提供帮助——对我来说最令人欣慰的是，他们真正理解我的问题。来自最大公司的 4 小时 SLA 的昂贵支持合同在相同的时间范围内产生的有效解决方案更少。在这一周里，我从根本性的失败到每天解决问题。从 Keystone 问题到 Nova 的错误配置；从 Horizon 错误到简单的用户错误——所有需要的只是保证和指导，我遇到了错误，或者只是简单的错误配置。

我得到了协助安装的建议，在 IRC 上进行特定问题的会话——对我来说同样重要的是，我得到了保证 OpenStack 正在使用并且有效。

在过去的几周里，在实际发布候选版本之前取得的进展简直令人惊叹。我试图用后续邮件向社区表达我的想法

Dear all,
You might know me from such emails as "Agggh, I can't get this thing to
work and its close to RC status!" and such bugs as "Why is this only
affecting me?" so I thought I'd share my gratitude to everyone that has
come out to help make life a lot less stressful for me.
Over the course of just a week I've gone from despair and frustration to
almost wanting to shout from the rooftops the achievements that have been
made in OpenStack and my own deployments and testing.
Whilst many of you might still be on that rocky road, I can assure you that
there is light at the end of the tunnel.  And it's quite bright too...

很明显，我的问题源于期望——既来自 OpenStack 和 Ubuntu。作为最终用户，当此最终用户负责推动战略时，OpenStack 是一种产品，而不仅仅是一组相互连接的 Python 脚本和项目。安装体验与软件的功能一样重要，以确保在企业环境中的采用。第一印象从这个关键阶段开始。解释您正在从 GitHub 上下载源代码补丁作为安装的一部分，这不是我想要批准或想要做的事情。

自从 Essex RC 包发布以来，安装变得轻而易举。信心很高，工作重心已经从虚假开始和尝试运行基本功能，转移到计划裸机配置和所需的特定配置步骤。

大家做得真棒，你们成功了！
