devstack默认安装过程要访问国外网站，安装软件，ｃｌｏｎｅ代码等，由于网络原因，经常失败。
经笔者总结，通过一下设置，基本半个过小时 就可安装控制节点
１５分钟左右可安装计算节点。
在每个节点上执行一下操作
（笔者用的是Ubuntu16.04，openstack是stable/pike）
- 设置DNS
参考这里http://www.alidns.com/setup/#linux
wget http://www.alidns.com/static/soft/SetAliDNS.sh -O SetAliDNS.sh && chmod +x SetAliDNS.sh && sudo ./SetAliDNS.sh
虽然ａｌｉ大名鼎鼎，但毕竟也受到审查，有事也莫名其妙解析不到某些网站，故建议添加8.8.8.8
root@compute1:~# vim /etc/resolvconf/resolv.conf.d/head
options attempts=2 timeout=2 rotate
nameserver 8.8.8.8
nameserver 223.5.5.5
nameserver 223.6.6.6
然后重启生效
- 修改ａｐｔ源
root@compute2:~# apt edit-sources
deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse
- 添加pip.conf
root@compute2:~# vim /etc/pip.conf
[global]
no-binary = libvirt-python
index-url = http://mirrors.aliyun.com/pypi/simple/
extra-index-url = https://pypi.douban.com/simple
timeout = 60
[install]
trusted-host=http://mirrors.aliyun.com
#ignore-installed = true
#no-dependencies = yes
#upgrade-strategy = only-if-needed
#no-compile = yes
#retries = 10
#disable-pip-version-check = yes
- 更新重启
root@compute2:~# apt update && apt -y upgrade && reboot
- 准备devstack安装
ｃｌｏｎｅ devstack代码
git clone http://git.trystack.cn/openstack-dev/devstack -b stable/pike
创建ｓｔａｃｋ用户
devstack/tools/create-stack-user.sh
移动代码（同后续安装目标目录放在一起）
mv devstack /opt/stack
chown -R stack:stack /opt/stack/devstack
切换到 stack 用户
su - stack
cd devstack
编辑local.conf，接下来每个节点的local.conf不一样
stack@compute2:~/devstack$ vim local.conf
控制节点

编写好local.conf后，执行安装，先安装控制节点，再安装计算节点。

最后，要让计算节点注册，在控制节点上运行
root@controller1:~# /opt/stack/devstack/tools/discover_hosts.sh
登录ｈｏｒｉｚｏｎ，查看服务

都正常启动了，暂时看来一切都很美好。。。
