准备虚拟环境

1. 在物理机上创建stack用户

sudo useradd stack
sudo passwd stack  # specify a password
echo "stack ALL=(root) NOPASSWD:ALL" | sudo tee -a /etc/sudoers.d/stack
sudo chmod 0440 /etc/sudoers.d/stack
su - stack

1. 配置yum源

   a

2. 安装instack-undercloud

   sudo yum install instack-undercloud -y

3. 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

4. 部署虚拟环境

   instack-virt-setup
