STEP1: 创建stack用户(一定要！)
sudo useradd -s /bin/bash -d /opt/stack -m stack
sudo chmod +x /opt/stack
echo "stack ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/stack
sudo -u stack -i //用stack用户登陆
STEP2: git clone devstack
git clone http://git.trystack.cn/openstack/devstack.git -b stable/zed //Key,Sucess
STEP3: 创建和修改local.conf
cd devstack //首先要用stack帐号登陆
vim local.conf //Create
官方文档的配置(单机版)+git.trystack.cn的说明

总结：
1. 一定要创建stack用户并按照STEP1来做。
2. 国内安装devstack时一定要使用国内的源（ubuntu、devstack、openstacck）。我用github的源安装了一整天都失败，用国内的源一次成功，用时110分钟！
3.因为OpenStack是用python写的，有些依赖可能pip会从外网下(可以设置pip为国内源)，但我这次安装很顺利，并没有改Pip源。
4.sudo su stack --login 该命令切换帐号为stack，当前目录切换到stack的home目录下
stack@controller:~$
5.执行安装devstack的脚本时一定要注意:1.用stack登陆；2.cd到/opt/stack/devstack目录下再运行stack.sh。 （stack@controller:~/devstack$ ./stack.sh ）
6.如果安装过程中出错(ERROR提示)，可打开“/opt/stack/logs/error.log”日志获得线索！
7.虚拟机的CPU推荐2-4核，内存8G，硬盘20G-30G（下图显示安装devstack后剩下6G了）
local.conf设置
devstack可以单机安装，也可以多机安装（控制节点、计算节点）
单机安装local.conf设置
/opt/stack/devstack/local.conf
