我正在尝试使用此处的任务定义在 ECS 上安装 Wordpress:https://docs.aws.amazon.com/AmazonECS/latest/developerguide/example_task_definitions.html 。我在 ECS(2 个容器)上有以下任务 - json 格式:

但由于某种原因worpdress容器无法连接到mysql容器。当我通过公共(public) IP 访问它时，我收到“建立数据库连接时出错”并在日志中
MySQL 连接错误:(2002) 连接被拒绝
我尝试在 WordPress 容器上添加 WORDPRESS_DB_HOST、WORDPRESS_DB_USER、WORDPRESS_DB_NAME 和 WORDPRESS_DB_PASSWORD 环境变量，但没有成功。
你能告诉我我做错了什么吗？ 谢谢
最佳答案
该问题是由新的mysql版本(8.0)更改了身份验证方法引起的。解决方案是使用较旧的 mysql 镜像 (5.17) 或在创建容器时使用此命令
default-authentication-plugin=mysql_native_password
关于mysql - ECS 上的 WordPress - 无法连接到 mysql 容器，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/57893325/
