使用yaml创建mysql服务时使用pvc作为持久存储，使用的yaml如下:

storageclass.yml

mysql-pv.yml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: mysql-pv
spec:
  capacity:
    storage: 1Gi
  accessModes:
    - ReadWriteOnce
  persistentVolumeReclaimPolicy: Retain
  storageClassName: nfs
  nfs:
    path: /nfsdata/mysql-pv
    server: 172.28.2.210

mysql-pvc.yml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pvc
spec:
