1. 系统准备
vmware虚拟机，2C4G，minimum安装，安装Developmen Groups,关selinux，关firewalld，校对系统时间
# 关闭防火墙
systemctl stop firewalld
systemctl disable firewalld
# 关闭selinux
setenforce 0
sed -i --follow-symlinks 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/sysconfig/selinux
2. 创建stack用户，下载devstack
sudo useradd -s /bin/bash -d /opt/stack -m stack
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
git clone https://git.openstack.org/openstack-dev/devstack
3. 安装rhel-epel、python-pip，git,配置豆瓣pip源
yum install epel-release
yum install -y python-pip
yum install -y git
mkdir /opt/stack/.pip
cat > /opt/stack/.pip/pip.conf << EOF
[global]
index-url = https://pypi.douban.com/simple/
EOF
4. 修改local.conf配置文件
复制/opt/stack/devstack/samples里面的local.conf到/opt/stack/devstack/，修改第一段设置统一的密码，添加第二段设置devstack的下载源为国内的trystack.cn
# 修改密码
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
# use TryStack git mirror
GIT_BASE=http://git.trystack.cn
NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git
5. 手工下载etcd
原先的github下载地址不可用了，安装过程会报错，自己手工下载一个放到/opt/stack/devstack/files下,下载地址https://storage.googleapis.com/etcd/v3.2.17/etcd-v3.2.17-linux-amd64.tar.gz
6. 安装devstack
/opt/stack/devstack/stack.sh
7. 报错处理
Obtaining file:///opt/stack/cinder

You are using pip version 9.0.3, however version 19.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
解决方法：升级setuptools
sudo pip install -U setuptools

内存不够，swap都用满了，解决方法，扩内存至4G。
安装完成
cd /opt/stack/devstack
source openrc admin
openstack user list
结果如下：
[stack@devstack devstack]$ openstack user list
