1.使用之前需要确认：

硬件：

6GB RAM或以上

网络设置：

$ sudo systemctl disable firewalld
$ sudo systemctl stop firewalld
$ sudo systemctl disable NetworkManager
$ sudo systemctl stop NetworkManager
$ sudo systemctl enable network
$ sudo systemctl start network

$ sudo yum install ntp

$ vim ~/.bash_profile
/etc/environment

LANG=en_US.utf-8
LC_ALL=en_US.utf-8

2.添加软件仓库

在CentOS上，存储Extras库提供启用OpenStack存储库的RPM。Extras在CentOS 7上默认启用，因此您可以直接安装RPM来设置OpenStack存储库：

$ sudo yum install -y centos-release-openstack-ocata
 sudo yum install -y centos-release-openstack-mitaka
更新
$ sudo yum update -y

3.安装Packstack安装程序

$ sudo yum install -y openstack-packstack

4.运行Packstack安装OpenStack

Packstack通过手动设置OpenStack来完成工作。对于单节点OpenStack部署，请运行以下命令：

$ sudo packstack --allinone
