OpenStack Redhat命令行操作

命令行删除

环境变量

OpenStack的九个组件必须熟记，命令不需要死记硬背，我们可以通过help来查询相关的命令和参数。
如果你直接使用命令来查询或者做其他操作，那么会涉及到环境变量，操作起来非常麻烦，比如：

所以需要提前加载好环境变量，而默认情况下创建好OP，会自动生成一个admin的环境变量文件：

文件内容：

那这个文件是如何生成的？
在应答文件中cloudcs.txt

如果你的环境没有这个文件，怎么办？
可以进行手工创建，也可以从其他地方拷贝一份。
现在有了admin的环境变量文件，我们就可以进行加载环境变量，让它变为admin的用户变量。

但是没有普通用户的环境变量，可以拷贝一份，然后进行修改

之后，就可以通过两个环境变量文件，快速切换。

查询租户信息(admin)

删除实例云主机(nova)

因为主机实例是在普通用户下创建的，所有切换普通用户
