Ubuntu 14下使用Devstack安装OpenStack Icehouse
1、下载Ubuntu 14.04 LTS：http://mirrors.hustunique.com/ubuntu-releases/14.04/ubuntu-14.04-server-amd64.iso
2、VMware Workstation创建虚拟机，网络选择NAT模式，安装下载的Ubuntu系统,配置网络，
记得配置DNS否则会有解析问题，8.8.4.4
3、 查看版本和更新系统
openstack@openstack:~$lsb_release –a #查看Ubuntu版本

E: Unable to locate package git #报错
openstack@openstack:~$ sudo apt-getupdate #先更新源
openstack@openstack:~$ sudo apt-get installgit #成功
openstack@openstack:~$sudo apt-get dist-upgrade #成功
5、openstack@openstack:~$ git clone https://github.com/openstack-dev/devstack.git
#下载源代码
6、openstack@openstack:~/devstack$ git branch –a #查看分支
* master
remotes/origin/HEAD-> origin/master
remotes/origin/master
remotes/origin/stable/havana
remotes/origin/stable/icehouse
openstack@openstack:~/devstack$ git checkout -b icehouseorigin/stable/icehouse
#切换分支
Branch icehouse set up to track remote branch stable/icehouse fromorigin.
Switched to a new branch 'icehouse'
openstack@openstack:~/devstack$ git branch –a
* icehouse 切换到icehouse版本
master
remotes/origin/HEAD ->origin/master
remotes/origin/master
remotes/origin/stable/havana
remotes/origin/stable/icehouse
7、新建localrc文件在/home/openstack/devstack下，然后将localrc内容粘贴进去（见附件）
8、执行./stack，我是一次成功，然后登陆提示的IP就可以看到openstack相关信息了
9、两个遇到的问题：若是提示目录权限问题，可手动创建即可；若是提示到neutron退出则在
devstack 目录下执行ll，看看localrc目录是否正常，特别是目录的名字。
10、创建主机后看是否能正常获取IP地址，3.0的镜像是不能的这书BUG，3.2正常，但是从主机是ping
不通云主机的，要按照如下修改安全组规则，放行ICMP和ssh，才可以从主机ping或者ssh上
云主机。
