mysql - 我无法在docker compose中进行mysql php artisan迁移。错误SQLSTATE [HY000] [2002]

Question

我目前正在使用docker compose开发一个laravel-vue-mysql环境。

我以这些文章为指导link link

我的docker compose工作正常，Web和应用程序服务运行良好，应按需进行部署。但是我无法配置我的数据库。
我正在尝试执行docker-compose exec app php artisan migrate，但是我有SQLSTATE没有此类文件或目录异常，因此在此卡住了3天。

我已经阅读了有关此问题的所有评论，但可以获得解决方案。我已将所有特权授予数据库中的root用户。我尝试使用容器ip或容器db名称更改dbhost，我也尝试过更改数据库名称的database.php主机，但是它也不起作用。

我认为我的错误可能在我的"unix_socket' => '/var/run/mysqld/mysqld.sock',"中

我想澄清一下这条路线，我是通过登录docker mysql服务并在我的数据库中输入命令获得的。我不知道我是否必须放置mysql.lock本地路由
这是 /tmp/mysql.sock

或者它可能是我的database_url路由，我不确定自己在做什么错。需要一些帮助。

我想在我的mysql docker服务中创建数据表

这是我的docker-compose.yml

首先，如果您执行docker exec app env | grep -e DB_ -e DATABASE，您只会看到

DB_PORT=3306
DB_HOST=database

这是由于 .env文件 purpose引起的。如果要在运行阶段在容器中设置其他变量，只需通过以下方式传递它们:

version: '2'
services:

  # The Application
  app:
...
    environment:
      - DB_CONNECTION=${DB_CONNECTION}
      - DB_HOST=${DB_HOST}
      - DB_PORT=${DB_PORT}
      - DB_DATABASE=${DB_DATABASE}
      - DB_USERNAME=${DB_USERNAME}
      - DB_PASSWORD=${DB_PASSWORD}
      - DATABASE_URL=${DATABASE_URL}

现在

docker exec app env | grep -e DB_ -e DATABASE
DB_CONNECTION=mysql
DB_HOST=database
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=root
DB_PASSWORD=secret
DATABASE_URL=mysql://root:@database:33061/homestead

您的应用容器知道如何与数据库通信
