systemctl enable nfs
mkdir /data
showmount -e 10.0.0.5 
#node节点：
docker pull quay.io/external_storage/nfs-client-provisioner:latest
yum -y install nfs-utils 
#master 节点

kubectl create -f mysql_pvc.yaml

设置默认动态存储
kubectl patch storageclass course-nfs-storage -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
