VirtualBox中使用ubuntu-16.04.1安装devstack的Compute节点
1、Controller节点主机配置4G内存，80G硬盘，2个网卡：bridged、internal network
bridged ----连接API及管理网络，上网
internal network ----连接租户网络，保证controller和compute的通信
2、OS安装
ubuntu-16.04.1-server-amd64，安装ssh和kvm（openssh-server和virtual machine host）组件
3、OS配置
[*]允许root远程登录
同controller
[*]网卡配置
vi /etc/network/interfaces
auto enp0s3
iface enp0s3 inet static
address 192.168.104.11
netmask 255.255.255.0
gateway 192.168.104.1
dns-nameservers 192.168.104.1
auto enp0s8
iface enp0s8 inet manual
systemctl restart networking.service ---重启网络服务
[*]更改apt源并进行update
同controller
4、部署openstack
[*] 安装pip
apt install python-pip
[*]下载openstack至/root/目录
git clone https://git.openstack.org/openstack-dev/devstack -b stable/newton
[*]创建stack用户
/root/devstack/tools/create-stack-user.sh ---创建用户
[*]配置pip，为root用户及stack用户设置国内镜像源
root用户下执行mkdir ~/.pip&&vi ~/.pip/pip.conf，将如下内容粘贴进入
stack用户下执行mkdir ~/.pip&&vi ~/.pip/pip.conf，将如下内容粘贴进入
index-url = https://pypi.douban.com/simple
download_cache = ~/.cache/pip
use-mirrors = true
mirrors = http://pypi.douban.com/
[*]配置local.conf
mv /root/devstack/ /opt/stack/ ----将root/devstack移动至stack用户目录
chown stack:stack /opt/stack/devstack -----文件夹权限修改
vi /opt/stack/devstack/local.conf，将如下内容粘贴进去
