php - 如何修复'ERROR 2002(HY000):无法通过套接字'/var/run/mysqld/mysqld.sock'(2“无此文件或目录”)连接到本地MySQL服务器

我正在尝试在laravel项目中安装docker。一切似乎都正常，除了当我尝试将数据导入漫画中时，出现以下错误：

我导入宽度命令行：

docker-compose exec app php artisan db:import --local

我还必须说，这是我要导入的大量数据


  错误2002（HY000）：无法通过套接字'/var/run/mysqld/mysqld.sock'连接到本地MySQL服务器（2“无此文件或目录”）


我曾在互联网上进行研究以找到解决方案。我看到很多，但没有一个与我同行。

我使用docker创建开发环境。这是我的配置

最佳答案

您需要连接到在docker容器中运行的数据库。

因此，您可能需要使用tcp（在您的情况下在13306端口上运行）而不是PHP代码中的unix套接字。
