eth0 做为 API_NET 接口，提供 OpenStack 的管理网络，我们给它分配一个静态IP，这里的地址需要和你的实际网络环境一致。
eth1 做为 EXT_NET 接口，提供 OpenStack 的 neutron 网络，这里我们启动网口但是不对它进行IP配置。
安装kolla环境，部署OpenStack with Ironic
更新apt源，安装依赖
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install Python-jinja2 python-pip libssl-dev -fy
配置 pip 加速，使用阿里云 pip 源
mkdir ~/.pip
