openstack keypair实践 登陆OS系统可以使用密码登录或者密钥登陆，密码登录是比较常见的一种方式，用户在操作系统中创建了用户名和密码，就可以使用自己的用户名和密码登录进去了；使用密钥登陆是另外一种方式，即用户创建一个密钥对（公钥和私钥），然后将公钥注入到OS中，在登陆时使用私钥校验，校验通过后就可以登入到OS。OpenStack提供了密钥登陆的功能，可以采用密钥注入或者文件注入的方式将公钥注入到OS中，本文采用了密钥注入的 阅读详情

OpenStack文件注入相关分析（1）

openstack在创建实例的时候可以将文件和相关的参数注入到实例的镜像中，来完成密码的设定、密钥的添加等动作，而这些动作的完成都是在实例启动之前。这在有些情况下会非常有用，比如修改root密码，注入ssh密钥，对实例的个性化定制等等。 1.相关源码的源码结构 文件和元数据注入是/nova/virt/disk/下的源码文件实现的，我们先来看一下/nova/virt/disk/的源码
