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

【中文标题】我无法在我的 docker compose 中进行 mysql php artisan 迁移。错误 SQLSTATE[HY000] [2002]

【英文标题】：I can't do mysql php artisan migrations in my docker compose. Error SQLSTATE[HY000] [2002]

【发布时间】：2020-06-19 04:55:27

【问题描述】：

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linklink

我的 docker compose 运行良好，网络和应用程序服务运行良好，并且部署正常。但我无法配置我的数据库。 我正在尝试执行docker-compose exec app php artisan migrate，但我的 SQLSTATE 没有这样的文件或目录异常，我被困了 3 天。

我已阅读有关此问题的所有 cmets，但可以找到解决方案。我已将所有权限授予我的数据库中的 root 用户。我尝试使用容器 ip 或容器数据库名称更改我的 dbhost，我也尝试为我的数据库名称更改 database.php 主机，但它也不起作用。

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

我想澄清这条路线，我是通过登录我的 docker mysql 服务并在我的数据库中输入一个命令获得的。我不知道我是否必须放 mysql.lock 本地路由 这是 /tmp/mysql.sock

或者它可能是我的 database_url 路由，我不确定我做错了什么。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

【问题讨论】：

您在.env 中的值有冲突。我不确定哪个会优先，但我建议让端口号、主机名等都匹配。

你会改变什么？

更改它，以免它们发生冲突。您的 URL 没有密码，但 DB_PASSWORD 有一个值。 URL 的端口与 DB_PORT 不同。

做到了。但它没有用。 ://

【参考方案1】：

首先如果你执行docker exec app env | grep -e DB_ -e DATABASE，你只会看到

DB_PORT=3306
DB_HOST=database

这是由于.env 文件purpose。如果您希望在运行阶段在您的容器中设置其他变量，只需通过这种方式传递它们：

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您的数据库通信

【讨论】：

我有一些问题。我应该在 .env 和 yml 中有相同的变量吗？我的意思是，我昨天用 app_key 变量更新了我的 .env 并且在我的 .yml（#database env 部分）中我应该在那里做同样的事情吗？

.env 文件是在执行 .yml 之前将变量设置为当前 compose 的环境（但在优先级和可见性方面与之前的 bash export 不同）。它对结果图像中出现的变量集没有直接影响。所以你需要在environment 部分设置变量，你可以直接硬编码它（如你的清单），或从.env 的环境中获取（如我的）。您也可以使用env_file 选项，但它的行为明显不同
