1 创建持久化目录

mkdir -pv /lzs/data/nfs-server/case-demo/wordpres/{wp,db}

2 编写资源清单

vim  19-pods-mysql-wordpress-nfs.yaml 


apiVersion: v1
kind: Pod
metadata:
  name: wordpress-db
  labels:
    apps: db
spec:
  volumes:
  - name: data
    nfs:
      server: 10.0.0.231
      path: /lzs/data/nfs-server/case-demo/wordpres/db
  nodeName: worker233  # 指定工作结点  （必须是k8s的主机名）
  hostNetwork: true 
  containers:
  - name: db
    image:  docker pull mysql:oraclelinux9   # 拉取镜像 （得翻墙）
    env:
    - name: MYSQL_ROOT_PASSWORD  #指定mysql的密码
      value: "123456" # 密码
    - name: MYSQL_DATABASE  # 传参 数据库创建库
      value: "wordpress"  # 库名
    - name: MYSQL_USER   # 1  数据库mysql的用户
      value: lzs
    - name: MYSQL_PASSWORD  # 2  数据库mysql密码
      value: liuzhisong
    volumeMounts:
    - name: data
      mountPath: /var/lib/mysql

---

apiVersion: v1
kind: Pod
metadata:
  name: wordpress-wp
  labels:
    apps: wp
spec:
  volumes:
  - name: data
    nfs:
      server: 10.0.0.231  
      path: /lzs/data/nfs-server/case-demo/wordpres/wp
  hostNetwork: true
  nodeName: worker232  # 指定工作结点 （必须是k8s的主机名）
  containers:
  - name: wp
    image: docker pull wordpress:php8.4-fpm  # 拉取镜像 （得翻墙）
    env:
    - name: WORDPRESS_DB_HOST
      value: "10.0.0.233"   # worker233 的ip地址
    - name: WORDPRESS_DB_NAME  # 指定数据库mysql的库
      value: "wordpress"
    - name: WORDPRESS_DB_USER  # 必须和上面的 1 一样
      value: lzs
    - name: WORDPRESS_DB_PASSWORD  # 必须和上面的 2 一样
      value: liuzhisong
    volumeMounts:
    - name: data
      mountPath: /var/www/html

3.创建资源

[root@master231 ~ ]# kubectl apply -f  19-pods-mysql-wordpress-nfs.yaml 
pod/wordpress-db created
pod/wordpress-wp created
[root@master231 ~ ]# 
[root@master231 ~ ]# kubectl get pods -o wide
NAME           READY   STATUS    RESTARTS   AGE   IP           NODE        NOMINATED NODE   READINESS GATES
wordpress-db   1/1     Running   0          5s    10.0.0.233   worker233   <none>           <none>
wordpress-wp   1/1     Running   0          5s    10.0.0.232   worker232   <none>           <none>

4.访问测试
