1 ）一键安装 openstack P版(Pike) 到单机

安装环境 CentOS 7.x ， 8G 内存 ，虚拟机或物理机都可以，能上网。

确认已安装了wget 和ntpdate

# which wget && which ntpdate

[root@opst-allinone yum.repos.d]# which wget && which ntpdate

    /usr/bin/wget

    /usr/sbin/ntpdate

创建一键安装脚本openstack_install.sh。用vi 编辑器打开脚本，拷贝下列内容到该文件，保存。

#!/bin/sh
# openstack pike 单机 一键安装
# 环境 centos 7.x.1708 x86_64
# Myde by Elven

[[ `uname -r` = *el7* ]] && { echo '开启安装openstack pike'; } || { echo '请在CentOS7.x 环境运行';exit; }
