学习openstack 安装实验环境，经过诸多挫折，顺利搭建，记录如下，以作备忘。

环境： linux ubuntu16.04.3 , 虚拟机上安装，openstack是由devstack安装版本stable/pike

两主机，一个是controller控制节点，安装所有组件，另一台是compute1计算节点

控制主机三个虚拟网卡，计算主机两个虚拟网卡

首先两台电脑安装 ubuntu16.04.3 server版，controller第一网卡设置静态ip：192.168.0.102, 计算节点compute第一个网卡ip：192.168.0.103，安装openssh 并设置允许root远程登录

分别在两台主机开始安装以下步骤：

1.修改apt为国内源

vi /etc/apt/sources.list

deb xenial main restricted universe multiverse

deb xenial-security main restricted universe multiverse

deb xenial-updates main restricted universe multiverse

deb xenial-proposed main restricted universe multiverse

deb xenial-backports main restricted universe multiverse

2.更新源

apt update

3.取得devstack代码

git clone -b stable/pike

4.创建stack用户

devstack/tools/create-stack-user.sh

5.移动目录

mv devstack /opt/stack

chown -R stack:stack /opt/stack/devstack

6.切换到 stack 用户

su - stack

cd devstack

7.编辑local.conf

在 /opt/stack/devstack 目录下，创建 local.conf，控制节和计算节点分别如下

---------------compute node special section

FLAT_INTERFACE=ens33

VNCSERVER_PROXYCLIENT_ADDRESS=$HOST_IP

VNCSERVER_LISTEN=$HOST_IP

8.执行安装脚本

./stack.sh

如果中途退出可以再次运行

也可以运行 ./unstack.sh ./clean.sh清理后重新再执行./stack.sh 直至安装成功
