水很深
前几天测试了一下devstack的安装，一切按照默认最简的方式进行，虽然最后也成功启动了，但是关键的Network一项竟然没有包含，这次重新来过，改用Ubuntu 14.04 Minimal CD安装系统，为了兼容公司和家里两个不同的网络环境，改用VirtualBox的Net Network模式来分配IP地址，如下配置VirtualBox的Net Network设置:
将Network CIDR修改为家里的无线网地址段，这样虚拟机拷回去之后就可以改成Bridge方式直接访问了，也不用做任何修改(后来证实这个做法不可行，移动之后的VirtualBox虚拟机，无法和外部通信，虽然可以DHCP获取到地址，但是却ping不通网关，不知道是不是openstack的配置在影响?)。为了在公司内使用，还需再做两个端口映射，访问ssh和dashboard:
这样配置好之后，将虚拟机内IP改为静态分配，修改/etc/network/interfaces:
# The primary network interface
auto eth0
#iface eth0 inet dhcp
iface eth0 inet static
address 192.168.1.110
netmask 255.255.255.0
gateway 192.168.1.1
还要配两DNS服务器，否则不能解析地址，修改/etc/resolvconf/resolv.conf.d/base，添加:
nameserver 114.114.114.114
nameserver 180.76.76.76
nameserver 8.8.8.8
接下来是devstack的配置文件local.conf，参考陈沙克的文章(作者牛人，链接戳此处)修改如下:

安装正常步骤开始安装，如果遇到错误，可以先运行clean.sh删除掉以前的环境重新开始。这次安装后，如愿看到了NetWork选项:
还有网络拓扑图:
初次接触，OpenStack太过强大，内容很多不是业余选手一时半会可以吸收的，还是读读手册吧，找到一本OpenStack Cloud Computing Cookbook - Third Edition True PDF(链接: magnet:?xt=urn:btih:889266F86FC59E9B725002953603B6359A35BED7)，先粗览一下。
