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 http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse

2.更新源

apt update

3.取得devstack代码

git clone http://git.trystack.cn/openstack-dev/devstack -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

--------------controller节点----------------------
[[local|localrc]]
MULTI_HOST=true

management & api network

Neutron options

NEUTRON_CREATE_INITIAL_NETWORKS=False
MULTI_HOST=1

---------------compute node common section

ENABLED_SERVICES=n-cpu,q-agt,n-api-meta,placement-client,n-novnc
NOVA_VNC_ENABLED=True
NOVNCPROXY_URL="http://$SERVICE_HOST:6080/vnc_auto.html"

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

HOST_IP=192.168.1.103
FLAT_INTERFACE=ens33
VNCSERVER_PROXYCLIENT_ADDRESS=$HOST_IP
VNCSERVER_LISTEN=$HOST_IP

ENABLED_SERVICES+=,c-vol

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

1. 安装成功屏幕
