echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack
sudo chmod 0440 /etc/sudoers.d/stack

su - stack

2. 配置yum源

a

4. 安装instack-undercloud

sudo yum install instack-undercloud -y 

5. 配置instack环境变量

export NODE_DIST=centos7
export NODE_COUNT=9
export NODE_CPU=2
export NODE_MEM=6144
export NODE_DISK=40
export UNDERCLOUD_NODE_CPU=4
export UNDERCLOUD_NODE_MEM=16384
export UNDERCLOUD_NODE_DISK=50
export DIB_LOCAL_IMAGE=CentOS-7-x86_64-GenericCloud-1611.qcow2

6. 部署虚拟环境
