概述
早就想用devstack去安装openstack了，但是自己的电脑内存才4g真的太小了，最近上了8g内存，果断开虚拟机装devstack。
devstack的基本概念大家可以去百度这里就不说了
要准备的东西
- ubuntu16.04
- Google
- 网络(最好是移动网，电信的出口带宽真的很快，和断网一样的快)
- 一部电影(推荐美国派，如果不知道美国派是什么，去百度。因为安装时间很长，所以最好来一部电影消磨时间)
- virtualbox
- 一颗坚信可以安装成功的心
devstack不可能会一次性安装完成openstack，所以出错了要学会解决，比如一个软件包不能下载，那么就自己在实体机挂代理下载好然后scp到虚拟机对应的文件夹中，还有要相信我的配置文件，运行一次./stack.sh不行那就再次运行一次，如果还是不行，那么./clean.sh ./unstack.sh，最关键的是要学会谷歌而不是百度，垃圾百度毁一生
安装Ubuntu虚拟机
首先虚拟机的配置能多少高就多少高，网卡选择桥接，之后正常安装ubuntu16.04，不要安装其他服务
配置ubuntu虚拟机
更新一下系统
sudo apt update && sudo apt upgrade
重启系统
之后openssh要安装上，之后在自己的实体机ssh到虚拟机，这样方便复制，还有git也要安装上。
sudo apt install openssh-server
sudo apt install git
接着给root用户设置密码
sudo passwd root
配置openssh使root用户可以登录
修改
sudo vim /etc/ssh/sshd_config
PermitRootLogin 修改为yes
之后重启ssh服务，在实体机用root登录
sudo service ssh restart
创建openstack用户，并且配置
创建用户
sudo useradd -s /bin/bash -d /opt/stack -m stack
让stack用户在使用sudo的时候不需要密码
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
切换到stack用户
sudo su - stack
安装下载devstack
因为国内的环境问题，所以下载的时候推荐使用trystack.cn的镜像
先创建一个文件夹
mkdir openstack
cd openstack/
git clone http://git.trystack.cn/openstack-dev/devstack
修改local.conf文件
cd devstack/
创建local.conf
touch local.conf
[[local|localrc]]

下面这三句话是使用trystack.cn的openstack镜像的意思
GIT_BASE=http://git.trystack.cn
NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git
上面这个配置文件有几个地方是要你去修改的
HOST_IP=192.168.1.107 你的主机ip
DATABASE_PASSWORD=woyaoxuehuilinux
ADMIN_PASSWORD=woyaoxuehuilinux
SERVICE_PASSWORD=woyaoxuehuilinux
SERVICE_TOKEN=woyaoxuehuilinux
RABBIT_PASSWORD=woyaoxuehuilinux
上面是一些openstack dashboard或者数据库等密码
HORIZON_BRANCH=master
KEYSTONE_BRANCH=master
NOVA_BRANCH=master
NEUTRON_BRANCH=master
GLANCE_BRANCH=master
CINDER_BRANCH=master
上面的master表示你下载的openstack所在的git分支，使用master就好了
SWIFT_BRANCH=master
HEAT_BRANCH=master
这上面两个参数也同理
FLOATING_RANGE="192.168.1.0/24"
这个参数的ip地址要和你的主机的ip地址处于同一网段
其他的参数自己研究把，反正不影响安装，记住百度很重要
安装
在这下面我会把我安装的时候碰到的错误详细的说出来
首先执行
./stack.sh
同志们，长征开始了
第一个报错
fatal: unable to access 'http://git.trystack.cn/openstack/requirements.git/': Failed to connect to git.trystack.cn port 80: Connection timed out
很明显的网络问题，我的方法是把local.conf中
GIT_BASE=http://git.trystack.cn
NOVNC_REPO=http://git.trystack.cn/kanaka/noVNC.git
SPICE_REPO=http://git.trystack.cn/git/spice/spice-html5.git
注释掉，在每一行前面加上#就好了
接着运行./stack.sh
第二个错误

明显又是网络问题
我只要把etcd-v3.1.7-linux-amd64.tar.gz这个包在实体机挂代理下载过来放到/opt/stack/openstack/devstack/files/下就好了
proxychains wget https://github.com/coreos/etcd/releases/download/v3.1.7/etcd-v3.1.7-linux-amd64.tar.gz
scp etcd-v3.1.7-linux-amd64.tar.gz root@192.168.1.107:/opt/stack/openstack/devstack/files/
接着运行./stack.sh
最后
幸运的是我碰到的问题不是特别多，而且当你看到下面的样子的时候你的openstack就已经安装完成了
但是安装的时间是真的长，一部电影看样子是不够了，幸好美国派不只有一部
