我在Ubuntu 14.04计算机上托管了一个独立的Chef服务器。使用最新版本按照https://learn.chef.io/install-and-manage-your-own-chef-server/linux/安装服务器。
当我尝试引导节点时，它会安装客户端版本11.x并运行。但是市场上的大多数烹饪书与客户11不兼容并且需要客户端12.x.
因此，我将客户端版本12.x作为参数提供给我的bootstrap命令，该命令将客户端版本12.x安装到节点以进行引导。但是这次我得到了HTTP 503 - 503＆＃34; Service Unavailable＆＃34;错误，无法完成引导。

答案 0 :(得分：1)
我终于弄明白了这个问题。 我支持公司代理和我得到的错误＆＃34; 503：服务不可用＆＃34;不是来自Chef Server的东西，而是它来自代理服务器:( 无论如何，使用＆＃34; no_proxy＆＃34;选项和添加Chef Server的fqdn解决了这个问题。 是的，这仍然没有回答它如何与厨师客户端v11.x一起使用的问题，但我确信这解决了这个问题：）
答案 1 :(得分：0)
您的系统上可能有knife的旧版本。运行knife --version进行确认，您应该会看到它将是旧的11.x版本。追踪该副本的来源（which knife或type -a knife）并将其删除。这通常意味着从预先存在的Ruby环境（如RVM）中卸载gem。
