VirtualBox + DevStack 2016-12-31
磕磕碰碰一周，终于看到了dashboard…谨以此文，记录下各种坑~
环境配置：VirtualBox5.1.12 + ubuntu16.04 + devstack(stable/newton)
- VirtualBox
- 下载安装
- 安装ubuntu1604
- 虚拟机配置
- devstack
- 准备
- 下载devstack代码
- 配置localconf
- 运行devstack
VirtualBox
下载，安装
https://www.virtualbox.org/
安装ubuntu16.04。
镜像 -> https://www.ubuntu.com/download/desktop/contribute?version=16.04.1&architecture=amd64
当然，你也可以装个麒麟操作系统 -> http://www.ubuntukylin.com/downloads/
虚拟机配置
最关键的是网络配置。创建虚拟机的时候，virtualbox会创建一个网卡1，使用NAT方式与外部通信。在部署devstack的时候，个人比较推荐添加另一个网卡，用于host(windows)和guest(ubuntu)的通信。
- 网络
virtualbox的配置如上图，记住mac地址，后面需要根据这个mac地址去ubuntu下配置网卡ip。在host(windows)上，给Host-Only Network#2， 配上ip地址192.168.152.1。在guest(ubuntu)上，找到mac是08:00:27:39:D5:CB的网卡，配上ip地址192.168.152.101(之后dashboard也会使用这个ip)。
配置完成后，ping应该能成功
- 系统
下面配置勉强够跑devstack，ε=ε=ε=(~￣▽￣)~
处理器数量：2
内存 ：4096MB
运行峰值 ：100%
硬件加速 ：VT-x/AMD-V 嵌套分页
devstack
官方指导手册 -> http://docs.openstack.org/developer/devstack/
最大的坑是天朝的网络。devstack在安装的时候，需要从git或是pypi上下载大量组件，但这些外网，是很难从我朝访问的。基本晚上7~11点，git和pypi下载的丢包率在20%，传输速率<10KB
准备
- ubuntu 源，如果觉得慢，可以使用163或者aliyun的源
- python 2.7，ubuntu 16.04默认安装，若手动安装
$ sudo apt-get install python- git
$ sudo apt-get install git- 创建stack用户
$ adduser stack
... type password ...
$ echo "stack ALL=(ALL) NOPASSWD: ALL" >> /etc/sudoers
$ su stack下载devstack代码
git clone https://git.openstack.org/openstack-dev/devstack -b stable/newton或
git clone https://github.com/openstack-dev/devstack -b stable/newton推荐从github上下载代码，稍微快那么一丢丢
配置local.conf
git clone成功后，看到devstack的目录，在devstack目录下创建local.conf文件，如下配置
- 密码配置
随便配，看心情
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD- git仓库
devstack默认会从https://git.openstack.org上下载openstack组件，那是相当的慢。故在local.conf必须要把仓库替换成其他源，国内推荐git.trystack.cn。注意，trystack用的是http，不是https
GIT_BASE=http://git.trystack.cn
or
GIT_BASE=https://github.com- branch
保证与devstack的branch一直，避免不可预知的问题
NOVA_BRANCH=stable/newton- Service/Dashboard IP
HOST_IP=192.168.152.101完整配置如下(还配了heat组件)
[[local|localrc]]
ADMIN_PASSWORD=secret
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD

FLAT_INTERFACE=enp0s8- pypi源
devstack默认python源为https://pypi.python.org，天朝访问非常慢。可以从https://www.pypi-mirrors.org/选一个国内的镜像，把镜像地址写到pip.conf文件，并放到/root/.pip/pip.conf以及/home/stack/.pip/pip.conf

stack@exxucao-VirtualBox:~/devstack$- dashboard
运行结束后，会看到屏幕提示dashboard在http://192.168.152.101/dashboard，但此时用浏览器去访问dashboard会提示Internal Server Error
这是因为此时dashboard并不允许通过192.168.152.101访问，需要手动把ip地址加到local_settings.py里的ALLOWED_HOSTS字段
$ vim /opt/stack/horizon/openstack_dashboard/local/local_settings.py
# If horizon is running in production (DEBUG is False), set this
# with the list of host/domain names that the application can serve.
# For more information see:
# https://docs.djangoproject.com/en/dev/ref/settings/#allowed-hosts
ALLOWED_HOSTS = ['*']重启apache2服务
$ sudo service apache2 restart
使用admin/secret登陆，就能看到
