Chef Chef-Client Run
为了测试 Chef-Client 的运行，我们需要将 Chef-Client 配置为使用托管的 Chef 或自己的托管服务器。
在调试模式下运行 Chef-Client
vipin@server:~$ sudo chef-client-l debug

检查最后一次 Chef 客户端运行的结果
为了检查最后一次 Chef-Client 运行，尤其是在我们开发新Cookbook时的失败问题，我们需要知道到底出了什么问题。尽管 Chef 在标准输出中打印了所有内容，但人们可能希望再次查看调试日志。
如果我们想测试，我们需要有一本编译失败的损坏的Cookbook。
user@server:~$ sudo chef-client
