Mysql 如何在kubernetes中部署multi-wordpress？

我尝试在kubernetes中部署wordpress/mysql。 我希望mysql和wordpress使用不同的卷。我正在尝试为wordpress编写nfs，为mysql编写hostpath

但是wordpress和mysql没有连接。我不知道为什么。谢谢你的帮助

这是我的密码： Mysql.yaml

apiVersion: v1
kind: Pod
metadata:
  name: mysql
  labels:
    app: mysql
spec:
  containers:
  - name: mysql
    image: mysql:5.7

    - containerPort: 3306
      protocol: TCP
    env:
    - name: MYSQL_ROOT_PASSWORD
      value: qwer1234
    volumeMounts:
      - name: mysql-volume
        mountPath: /var/lib/mysql
  volumes:
      - name: mysql-volume
        persistentVolumeClaim:
          claimName: mysql-pvc

您最后在环境变量中提供了端口号

请试一试

env:
        - name: WORDPRESS_DB_HOST
          value: mysql:3306

用这个代替

env:
        - name: WORDPRESS_DB_HOST
          value: MySQL

您可以在以下位置查看示例：

如果您阅读了Docker image的文档，那么它们也提供了主机名，而没有端口作为值

同样在Wordpress环境中，您必须传递错误的MySQL密码

- name: WORDPRESS_DB_PASSWORD
          value: P@ssw0rd

应该是这样

- name: WORDPRESS_DB_PASSWORD
          value: qwer1234

你好，谢谢你的建议。但它仍然不起作用。我尝试连接192.168.201.200:30687此ip。但是它没有显示任何东西..啊，我修复了wordpress密码和mysql密码。现在它们都是一样的。一旦尝试直接打开负载平衡器IP而不检查端口80，就会显示“建立数据库连接时出错”，因此我检查了有关mysql的日志。[注意]用户'root'@'10.233.120.57'（使用密码：否）的访问被拒绝，我使用'kubectl descripe mysql'命令查看可能发生的情况，`/var/run/secrets/kubernetes.io/serviceCount from default-token-swz8d（ro）卷：mysql卷：Type:PersistentVolumeClaim（对同一名称空间中PersistentVolumeClaim的引用）default-token-swz8d:Type:SecretName:default-token-swz8d不是服务帐户的原因吗？好的！！！！我做到了！！！！！！！！！！！！！我猜它是由nfs文件系统引起的。我在这个sudo vi/etc/exports/nfs卷*（rw，sync，no_subtree_check）sudo mkdir/nfs volume sudo chmod-R 777/nfs volume sudo exportfs-arv和success！谢谢你！反对什么？这是一个很好的操作员/ui来管理你的安装。不需要困难的和自定义的安装。
