刚刚安装了 Laravel Sail。如何连接数据库？

Question

自 6 月起，我尝试在数据库中使用 TablePlus（或 PhpStorm）连接并创建架构。请理解我应该做什么？我将逐步描述我做了什么。

1. $ laravel new app。我的新项目有 /app/ 文件夹。
2. cd app/进入该文件夹。
3. composer require laravel/sail --dev接收 Laravel Sail。
4. php artisan sail:install。终端询问我想安装哪些服务？。我编写mysql并按 Enter 键。
5. gedit .env打开 .env 文件以查看连接设置。

APP_ENV=local
APP_KEY=base64:fXZ06W8BPoRShk8cYlHgS0u/+IBIZTSOM20gFRON6d4=
APP_DEBUG=true
APP_URL=http://app.test

LOG_CHANNEL=stack
LOG_LEVEL=debug

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=app
DB_USERNAME=sail
DB_PASSWORD=password

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120

MEMCACHED_HOST=memcached

REDIS_HOST=redis
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_MAILER=smtp
MAIL_HOST=mailhog
MAIL_PORT=1025
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null
MAIL_FROM_ADDRESS=null
MAIL_FROM_NAME="${APP_NAME}"

AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_DEFAULT_REGION=us-east-1
AWS_BUCKET=

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=
PUSHER_APP_CLUSTER=mt1

MIX_PUSHER_APP_KEY="${PUSHER_APP_KEY}"
MIX_PUSHER_APP_CLUSTER="${PUSHER_APP_CLUSTER}"

6. gedit docker-compose.yml在这里查看这些设置。

        ports:

        environment:

            MYSQL_DATABASE: '${DB_DATABASE}'
            MYSQL_USER: '${DB_USERNAME}'
            MYSQL_PASSWORD: '${DB_PASSWORD}'
            MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'
        volumes:
            - 'sailmysql:/var/lib/mysql'
        networks:
            - sail
        healthcheck:
          test: ["CMD", "mysqladmin", "ping"]
networks:
    sail:
        driver: bridge
volumes:
    sailmysql:
        driver: local

7. sail up -d运行 Sail。
8. 运行 TablePlus 以连接到数据库。我应该在主机中写什么？当我编写 mysql 时，出现错误“未知 MySQL 服务器mysql”。请帮忙！

Answer 1

从 TablePlus 中，连接到的主机将是127.0.0.1. mysql是 TablePlus 无法访问的 Docker Compose 网络内的主机名。

参考号 https://docs.docker.com/compose/networking/

# if your local environment has mysql-client, this will connect to the database
mysql --port=3306 --host=127.0.0.1 --user=sail --password

# from your project directory
./vendor/bin/sail mysql

# via docker exec
docker ps | grep mysql
docker exec -it YOUR-MYSQL-CONTAINER-NAME mysql --password
