Chef学习之五：Knife bootstrap 一台 Ubuntu EC2 机器
之前bootstrap一台windows 的机器失败了，很挫败，那只能在云上起一台Linux机器作尝试了。
这次学习的是bootstrap命令，简单来说，这个命令就是在目标机器上安装Chef-Client程序，使之变成Chef Servers所能管理的node。
下面是简单的步骤：
1. 在亚马逊上起一台Unbuntu 12.10的EC2。
2. 在Ruby环境下，Chef-repo下，执行命令：“D:\Tools\Chef\chef-repo-master>knife bootstrap ec2-54-234-202-177.compute-1.amazonaws.com -x ubuntu -i E:\Projects\CloudSeed\AwsSelfUse\myKey.pem --sudo”。
-x：指定用户名
-P：用来指定密码（但是我是通过-i指定一个pem文件来进行认证的）
--sudo：表示在管理员权限下执行。
执行之后，会有如下的输出：

3. 验证下，这台EC2已经变成了一个node，执行：D:\Tools\Chef\chef-repo-master>knife client list，可以看到如下输出，第一个就是那台EC2：
ip-10-202-85-20.ec2.internal pch-validator
3. 也可以使用命令来查询该node的信息：D:\Tools\Chef\chef-repo-master>knife client show ip-10-202-85-20.ec2.internal
admin: false chef_type: client json_class: Chef::ApiClient name: ip-10-202-85-20.ec2.internal public_key:
