###使用Saltstack自动部署Openstack集群。
1.Openstack架构
2.目录结构

1.每个服务均有一个SLS目录。每个目录下均有SLS和files目录。files目录放置源码包和配置文件。 2.每个服务均有一个Pillar文件，主要定义和配置相关的如IP地址、网络接口、用户名和密码等。
1.下载SLS和源码安装包
# git clone https://github.com/unixhot/saltstack-openstack
# cd saltstack-openstack
# ./openstack_source.sh2.修改Pillar目录的各个服务的配置
3.修改top.sls
All-In-One(所有服务均安装在一台服务器)
