使用Docker部署laravel项目时获取mysql错误

我想用和远程服务器一样的inviroment测试我的laravel项目。所以我尝试使用Docker（以前从未知道）。我安装了docker，并按照project中的说明使用docker部署它。 设置

将文件.env.example复制到.env，将docker-compose.yml.example复制到docker-compose.yml

修改.env配置文件（可选）。如果修改.env文件中的mysql、mongo和redis配置，请记住也要修改docker-compose.yml文件中的配置。 安装或运行Docker

docker-compose up -d

//停止

docker-compose stop

chmod缓存文件夹

chmod -R 777 storage

chmod -R 777 bootstrap/cache

部署

sh deploy.sh

运行

sh doploy.sh

后，我出现以下错误：

   [Illuminate\Database\QueryException]

文件“docker compose.yml”：

文件“.env”：

对于一个简单的laravel应用程序，您的设置相当复杂。问题是，您的laravel应用程序试图连接到自己容器中的

MySQL

服务器实例

---

将

DB\u HOST=localhost

更改为

DB\u HOST=mysql

以连接到

mysql

容器。

DB\u HOST应该是您的mysql服务名称，它是

mysql

，而不是

localhost

，我找到了答案，谢谢
