有人可以告诉我我做错了什么吗？或者修复我试图运行的代码/堆栈？我不是一个有经验的用户。

过去我删除了其他 Wordpress 安装，我认为这可能会导致冲突......我不知道......我在互联网上搜索的堆栈文件中尝试了一些差异，重命名了容器，但我不断收到同样的错误，而且我没有想法。

任何解决方案将不胜感激。谢谢。

我正在运行 Open Media Vault > Docker > Portainer。

您在 . 的同一根目录下绑定多个卷wordpress_multi_2。这不是安装卷的好方法。将它们拆分为单独的文件夹（例如/wp和/db）。并且不要绑定 1024 以下的端口，因为它们是保留的，明文 HTTP 端口的通用约定就像开发机器上的 8080。

wordpress_multi_1:
    ...
    ports:
      - 8080:80
    ...
    volumes:
      - /srv/dev-disk-by-label-1TB/Config/wordpress_multi_1/wp:/var/www/html

db_multi_1:
    ...
    volumes:
      - /srv/dev-disk-by-label-1TB/Config/wordpress_multi_1/db:/var/lib/mysql

wordpress_multi_2: #2nd_instance
    ...
    ports:
      - 8081:80
    ...
    volumes:
      - /srv/dev-disk-by-label-1TB/Config/wordpress_multi_2/wp:/var/www/html

db_multi_2: #2nd_instance
    ...
    volumes:

我终于让它工作了！！我什至运行了第二个安装了 3 和 4 的 Stack 来检查一下！

按照您的建议，我更改了路径和端口，并在代码中添加了一些东西，老实说，我不确定什么有效，但它有效！

我添加了这个：

links:
  - db_multi_1
depends_on:
  - db_multi_1
command: --default-authentication-plugin=mysql_native_password

我注意到的一件事是 mysql 容器需要几分钟才能完全启动，只有在那之后，wordpress / MY-IP:8001 才能正常工作。

感谢您为我指明正确的方向。

全栈：

version: '2.1'

services:

  wordpress_multi_1:
    image: wordpress
    restart: always
    ports:
      - 8001:80 ##change_this to above 1024
