解决方法，改成无头服务

apiVersion: v1
kind: Endpoints
metadata:
  name: mysql-server
subsets:
  - addresses:
    - ip: 192.168.5.159
    ports:
    - port: 3306
      protocol: TCP
---
apiVersion: v1
kind: Service
metadata:
  name: mysql-server
spec:
  type: ClusterIP
  clusterIP: None
  ports:
  - port: 3306
    targetPort: 3306
    protocol: TCP
