1、安装nfs存储服务器--server端

	# 安装nfs
	yum install -y nfs-utils
	# 创建nfs目录
	mkdir -p /nfs/data/
	mkdir -p /nfs/data/mysql
	# 授予权限
	chmod -R 777 /nfs/data
	# 编辑export文件
	vi /etc/exports
	  /nfs/data *(rw,no_root_squash,sync)
	# 使得配置生效
	exportfs -r
	# 查看生效
	exportfs
	# 启动rpcbind、nfs服务
	systemctl restart rpcbind && systemctl enable rpcbind
	systemctl restart nfs && systemctl enable nfs
	# 查看rpc服务的注册情况
	rpcinfo -p localhost
	# showmount测试
	showmount -e ip(ip地址)

2、在每个节点上安装nfs--客户端

	yum -y install nfs-utils
	systemctl start nfs && systemctl enable nfs

 3、自定义PV--mysql-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
    name: mysql-pv
    namespace: app
    labels:
      cloud: lle-pv-mysql
spec:
    capacity:
       storage: 5G
    volumeMode: Filesystem
    accessModes: ["ReadWriteMany"]
    persistentVolumeReclaimPolicy: Delete
    storageClassName: test-mysql
    nfs: 
         path: /nfs/data/mysql
         server: 192.168.3.42

4、自定义PVC--mysql-pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mysql-pvc
  namespace: app
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 5G
  storageClassName: lle-test-nfs-mysql
  volumeMode: Filesystem
  volumeName: mysql-pv

 5、自定义mysql的用户名和密码--mysql-secert.yaml

将用户名和密码进行加密放入到secret里面

apiVersion: v1
kind: Secret
metadata:
  name: mysql-user-passward
  namespace: app
data:
  username: cm9vdAo=
  password: V3d3LjEuY29tCg==

6、设置私有镜像仓库harbor的镜像访问-- harbor-secert.yaml

apiVersion: v1
kind: Secret
metadata:
  name: harbor-secert
data:
  .dockerconfigjson: ewoJImF1dGhzIjogewoJCSIxOTIuMTY4LjMuNDIiOiB7CgkJCSJhdXRoIjogIllXUnRhVzQ2VjNkM0xqRXVZMjl0IgoJCX0KCX0KfQ==
type: kubernetes.io/dockerconfigjson

7、编辑mysql的yaml文件--deployment---mysql.yaml

kind: Deployment
metadata:
  namespace: app
  name: mysql
spec:
  selector:
    matchLabels:
      app: mysql
  strategy:
    type: Recreate
  template:
    metadata:
      labels:
        app: mysql
    spec:
      containers:
      - image:  192.168.3.42/k8s/mysql:latest
        name: mysql
        env:
          # Use secret in real usage
        - name: MYSQL_ROOT_PASSWORD
          valueFrom:
            secretKeyRef:
              name: mysql-user-passward
              key: password
        ports:
        - containerPort: 3306
          name: mysql
        volumeMounts:
        - name: mysql-pvc
          mountPath: /var/lib/mysql
      imagePullSecrets: 
      - name: harbor-secert
      volumes:
      - name: mysql-pvc
        persistentVolumeClaim:
          claimName: mysql-pvc
