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

[global]
index-url = https://pypi.douban.com/simple
download_cache = ~/.cache/pip
[install]
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

[[local|localrc]]

• 执行安装脚本

　　/opt/stack/devstack/stack.sh             ---需N多次执行才可以完成安装
