环境准备

Ubuntu 18.04虚拟机 8G RAM 100G存储

下载pip

sudo apt install python-pip
pip install --upgrade pip
sudo pip install -U os-testr

更换pip源

mkdir .pip
vi .pip/pip.conf
#写入以下内容
[global]
index-url = http://pypi.douban.com/simple/
trusted-host = pypi.douban.com

root用户下修改pip源

#需要先为su设置初始密码
sudo passwd
#输入密码
su - #切换到root用户，并使用root的环境变量，如果不加“-”，则会使用原用户的工作目录和环境变量
#更改pip源
mkdir .pip
vi .pip/pip.conf
#写入以下内容
[global]
index-url = http://pypi.douban.com/simple/
trusted-host = pypi.douban.com

更换apt源

mv /etc/apt/sources.list /etc/apt/sources.list.bak
vi /etc/apt/sources.list
#添加以下内容
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
#这是国内的阿里云源，也可以自行更换其他

apt-get update
apt-get upgrade

如果遇到以下报错

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) 
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? 

执行以下命令再进行更新

rm /var/lib/dpkg/lock-frontend

Devstack安装OpenStack

下载devstack（可以选择切换到稳定分支）

sudo apt-get install git
git clone https://github.com/openstack-dev/devstack
cd devstack
git checkout remotes/origin/stable/stein
git checkout -b stein

创建配置文件

vi local.conf
#输入以下内容
[[local|localrc]]
# Define images to be automatically downloaded during the DevStack built process.
DOWNLOAD_DEFAULT_IMAGES=False
IMAGE_URLS="http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img"

# 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/sice-html5.git


# Credentials

#FLAT_INTERFACE=enp0s3

HOST_IP="your vm ip"

进入files目录先行下载所需要的文件

cd files/
wget -c https://github.com/coreos/etcd/releases/download/v3.1.10/etcd-v3.1.10-linux-amd64.tar.gz
wget -c https://github.com/coreos/etcd/releases/download/v3.1.7/etcd-v3.1.7-linux-amd64.tar.gz
wget -c https://github.com/coreos/etcd/releases/download/v3.3.12/etcd-v3.3.12-linux-amd64.tar.gz
wget https://bootstrap.pypa.io/get-pip.py

回到devstack目录执行安装脚本

cd ..
./stack.sh

出现g-api service not start的问题

尝试手动systemctl start g-api，之后再执行./stack.sh，问题依旧存在

最后通过执行./unstack.sh，./clean.sh再执行./stack.sh，问题没有再出现
