3.2：配置layout.yaml文件
#在dev-box机器上checkout,选择需要安装的OpenPAI版本
cd pai #切换到pai目录下
git checkout v1.6.0 #选择v1.6.0版本
#在dev-box机器上编辑并详解layout.yaml文件
vim /root/pai/contrib/kubespray/config/layout.yaml
# GPU cluster example
# This is a cluster with one master node and two worker nodes
machine-sku: #master节点配置段
master-machine: # define a machine sku
# the resource requirements for all the machines of this sku
# We use the same memory format as Kubernetes, e.g. Gi, Mi
# Reference: https://kubernetes.io/docs/concepts/configuration/manage-resources-containers/#meaning-of-memory
mem: 45Gi #最大分配内存，如果有50G，建议写45G
cpu:
# the number of CPU vcores
vcore: 4 #CPU的核心数，条件有限，所以这里是4C，如果是GPU型的建议是8C
gpu-machine: #GPU的worker配置项，因为没有纯GPU服务器，所以这里只需要改下内存大小和CPU核心数，后面安装时选择跳过即可。
computing-device:
# For `type`, please follow the same format specified in device plugin.
# For example, `nvidia.com/gpu` is for NVIDIA GPU, `amd.com/gpu` is for AMD GPU,
# and `enflame.com/dtu` is for Enflame DTU.
# Reference: https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/
type: nvidia.com/gpu #默认选择的是Nvidia官方驱动
model: K80
count: 4
mem: 18Gi #内存是18GB
cpu:
vcore: 4 #CPU核心数是4C
machine-list: #配置应用项
- hostname: pai-master # name of the machine, **do not** use upper case alphabet letters for hostname
hostip: 10.12.50.202 #openpai的master节点IP
machine-type: master-machine # only one master-machine supported
pai-master: "true" #引用上面定义的master-machine
- hostname: pai-worker1
hostip: 10.12.50.200 #openpai的worker节点IP

3.3：配置config.yaml文件
