【问题描述】：

我已经尝试了几个小时在我的 Laravel 项目和本地 MAMP 服务器之间建立数据库连接。

当我从我的 Mac 上的终端运行命令时，迁移工作。当我在我的 vagrant box 中运行它时，它不起作用。

iMac-van-Tim:myProject timcreemers$ php artisan migrate:status
+------+--------------------------------------------+-------+
| Ran? | Migration                                  | Batch |
+------+--------------------------------------------+-------+
| Yes  | 2014_10_12_000000_create_users_table       | 1     |
| Yes  | 2019_08_19_000000_create_failed_jobs_table | 1     |
+------+--------------------------------------------+-------+

但是当我运行我的应用程序时，我得到了这个错误：

Illuminate\Database\QueryException
SQLSTATE[HY000] [2002] No such file or directory (SQL: select * from `users`)

当我在http://localhost:8888/ 上连接到我的 MAMP 服务器时，它会显示这些设置：

Host    localhost
Port    8889
User    root
Password    root
Socket  /Applications/MAMP/tmp/mysql/mysql.sock

我的 .env 文件：

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=8889
DB_DATABASE=myproject
DB_USERNAME=root
DB_PASSWORD=root

我清空了我的 config/database.php 文件中的属性，因为该文件从 .env 中检索它们：

        'driver' => 'sqlite',
        'url' => env('DATABASE_URL'),

    ],

],

    ],

],

我尝试了许多解决方案，但似乎没有一个有效：

在 unix_socket 属性中添加 /Applications/MAMP/tmp/mysql/mysql.sock
在 localhost 和 127.0.0.1 之间切换 DB_HOST（两种方式都试过）
重新启动我的 MAMP 服务器

我检查了socket路径，发现了一个mysql.sock.lock文件，不知道有没有问题？

iMac-van-Tim:bin timcreemers$ cd /Applications/MAMP/tmp/mysql/
iMac-van-Tim:mysql timcreemers$ ls
mysql.pid       mysql.sock      mysql.sock.lock

根据我的阅读，它可能与套接字有关，但不幸的是我对此一无所知。谁能解释一下 vagrant box 应该如何与 MAMP 服务器一起工作？

此外，为数据库同时使用 Homestead 环境和 Mamp 服务器是否是一种好习惯？还是这让事情变得不必要地复杂化了？

我在这里有点绝望，谁能指出我正确的方向？提前致谢！

【问题讨论】：

你在 Laracasts 上查看过这个 thread 吗？此外，首选使用 Homestead。
我也关注了这个帖子，但我一直收到同样的错误。我删除了 mamp 服务器，现在只使用宅基地。感谢您的帮助！

【解决方案1】：

如果您在 Mac 上使用 MAMP，有时您需要为套接字添加设置并使用“localhost”而不是 127.0.0.1

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=8889
DB_DATABASE=database_name
DB_USERNAME=root
DB_PASSWORD=root
DB_SOCKET=/Applications/MAMP/tmp/mysql/mysql.sock
