您好，应该在 Ubuntu 20.04 上的 Docker 上直接安装 Wordpress 和 PHPMyadmin 会在 STDOUT 中引发错误，随后尝试在浏览器中查看 WordPress 时出现非特定数据库错误。
首先我的yaml文件:
version: '3'
services:
db:
image: mysql:8
container_name: mysql
restart: always
command: '--default-authentication-plugin=mysql_native_password'
environment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wpdb
MYSQL_USER: user
MYSQL_PASSWORD: password
wordpress:
image: wordpress:5.4.1
container_name: wordpress
restart: always
volumes:
- ./wp-content:/var/www/html/wp-content
depends_on:
- db
environment:
WORDPRESS_DB_HOST: db
WORDPRESS_NAME: wpdb
WORDPRESS_USER: user
WORDPRESS_PASSWORD: password
ports:
- 8080:80
- 443:443
phpmyadmin:
image: phpmyadmin/phpmyadmin
restart: always
ports:
- 3333:80
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: password
And Now the output from **docker-compose up**
Starting mysql ... done
Starting test2_phpmyadmin_1 ... done
Starting wordpress ... done

正如我在尝试访问 上的 WordPress 时所说的那样本地主机:8080 我明白了
建立数据库连接时出错
PhpMyadmin 在 上运行良好本地主机:3333
有任何想法吗？？？？？？？
哦，是的，我一直在关注本教程:https://www.youtube.com/watch?v=BfrVWwJv8ls
谢谢 : )
最佳答案
该错误表明 WordPress 无法连接到您的数据库容器。原因可能是由于 WordPress 不知道凭据，因为传递给 WP 容器的 ENV 变量没有使用它期望的 key 。
如果您调整用于 WP 容器的键以匹配您在此处看到的键:https://docs.docker.com/compose/wordpress/它应该运行。试试这样:
version: '3'
services:
db:
image: mysql:8
container_name: mysql
restart: always
command: '--default-authentication-plugin=mysql_native_password'
environment:
MYSQL_ROOT_PASSWORD: password
MYSQL_DATABASE: wpdb
MYSQL_USER: user
MYSQL_PASSWORD: password
wordpress:
image: wordpress:5.4.1
container_name: wordpress
restart: always
volumes:
- ./wp-content:/var/www/html/wp-content
depends_on:
- db
environment:
WORDPRESS_DB_HOST: db
WORDPRESS_DB_NAME: wpdb
WORDPRESS_DB_USER: user
WORDPRESS_DB_PASSWORD: password
ports:
- 8080:80
- 443:443
phpmyadmin:
image: phpmyadmin/phpmyadmin
restart: always
ports:
- 3333:80
environment:
PMA_HOST: db
MYSQL_ROOT_PASSWORD: password
