Devstack 部署 OpenStack
试验发现在 Host 为 Ubuntu20.04 和 22.04 上无法顺利安装 VirtualBox，请在 Ubuntu18.04 上安装 VirtualBox。虚拟机镜像版本为 Ubuntu20.04，以下步骤可以稳定复现，OpenStack master（c424a7a299e37004d318107648bb18e157344985）版本。
总而言之，在 18.04 版本上安装 VirtualBox，在 20.04 版本上安装 OpenStack。
因为安装 OpenStack 容易破话系统包依赖，如果为了学习建议在虚拟机中安装。
安装过程中需要下载镜像，请确认机器可以访问外网。
安装 VirtualBox
sudo apt update
sudo apt install virtualbox virtualbox-ext-pack
确认 VirtualBox 配置
请确认 VirtualBox 配置如下，VirtualBox 默认配置硬盘为 10G，远远不够用，为了避免后续的麻烦，请确认如下配置：
磁盘大于 100G
内存大于 16G
CPU 大于 4 个
下载镜像并安装
镜像可以去清华大学开源软件镜像站 | Tsinghua Open Source Mirror下载。

安装基础包
sudo apt update
sudo apt install git
sudo apt install aptitude
aptitude 用于解决包依赖冲突。
添加用户
添加 stack 用户
sudo useradd -s /bin/bash -d /opt/stack -m stack
授予 sudo 权限
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
切换到 stack 用户
sudo su - stack
PIP 配置
cd && mkdir -p .pip && cd .pip && bash -c "cat << EOF > ~/.pip/pip.conf
[global]
timeout = 6000
index-url = http://mirrors.aliyun.com/pypi/simple/
trusted-host = mirrors.aliyun.com
EOF"
仓库下载
git clone https://github.com/openstack/devstack --depth 1
配置 local.conf
只需要修改 HOST_IP，其他的可以不用修改，HOST_IP 为本机 IP 地址，可以使用 ifconfig 查看。如果是虚拟机就是虚拟机的 IP，virtualbox 创建的虚拟机默认为 10.0.2.15。
cd devstack && touch local.conf && bash -c "cat << EOF > /opt/stack/devstack/local.conf
[[local|localrc]]
HOST_IP=10.0.2.15
GIT_BASE=http://git.trystack.cn
ADMIN_PASSWORD=user
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
