学习笔记：openstack 实验环境安装
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
也可以修改pip源
#vi /etc/pip.conf
[global]
no-binary = libvirt-python
index-url = http://mirrors.aliyun.com/pypi/simple/
extra-index-url = https://pypi.douban.com/simple
timeout = 60
[install]
trusted-host=http://mirrors.aliyun.com
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

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
9. 安装成功屏幕
