Wordpress+mysql helm 部署

Wordpress+mysql helm deployment

学习kubernetes，docker和helm；我正在研究 Devops 程序，并被要求在我的实习企业中部署 wordpress+mysql 和 helm。试图做一些事情，但 wordpress 无法连接到数据库，我认为数据库无法写入已安装的 nfs 卷路径；如果可能的话，真的需要帮助和解释。尝试了我看到的一切，但没有奏效。

我在网络浏览器中从 wordpress 得到的错误是连接数据库时出错

这是我的项目清单文件，pods状态

在此先感谢您的帮助。真的很需要

检查一下你的DB密码和你加入的WordPress连接密码是不一样的，最好是一样。

MYSQL_ROOT_PASSWORD : root 但 WORDPRESS_DB_PASSWORD: test123 尝试更新 Wordpress 的密码，以便它可以连接到 MySQL.

WORDPRESS_DB_NAME 您已将此数据库创建到 MySQL 中还是只是添加名称？直接地？这可能是由于 Wordpress 查找该数据库而您尚未创建它。尝试按照这个官方 tut 并按原样检查一次：https://kubernetes.io/docs/tutorials/stateful-application/mysql-wordpress-persistent-volume/ 只有大部分相同
