我目前正在关注lynda的laravel / mysql教程，并按照以下步骤创建数据库并将其连接到我的laravel框架。
以下步骤有助于命名我的数据库，更改我的用户名和密码（不再是用户：root，密码：root）：
1. CREATE DATABASE landon_app;
2. CREATE USER 'landon_app'@'localhost' IDENTIFIED BY 'landon_app';
3. GRANT ALL ON landon_app.* TO 'landon_app'@'localhost';
执行此操作后，我可以在命令行上运行：mysql -u -landon_app -plandon_app
并且mysql启动并运行。
但问题是，在我创建迁移并设置表架构和所有内容后，我收到错误消息
SQLSTATE[HY000] [1045] Access denied for user 'landon_app'@'localhost' (using password: YES) (SQL: select * from information_schema.tables where table_sc
hema = landon_app and table_name = migrations)
SQLSTATE[HY000] [1045] Access denied for user 'landon_app'@'localhost' (using password: YES)
我已经更新了我的.env文件：
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=landon_app
DB_USERNAME=landon_app
DB_PASSWORD=landon_app
为什么会这样，并且有其他人碰到类似的东西？我想，因为命令行mysql -u -landon_app -plandon_app正在运行，php artisan migrate
一切都会有所帮助！
谢谢！

可能PHP使用的是TCP连接，而不是套接字连接。在这种情况下，您需要127.0.0.1的权限。
1. CREATE USER 'landon_app'@'127.0.0.1' IDENTIFIED BY 'landon_app';
2. GRANT ALL ON landon_app.* TO 'landon_app'@'127.0.0.1';
或者您需要指定DB_SOCKET来定义套接字。您可以使用以下命令获取此信息：
mysql > show variables like '%socket%';
+-----------------------------------------+------------------------------+
| Variable_name | Value |
+-----------------------------------------+------------------------------+
| performance_schema_max_socket_classes | 10 |
| performance_schema_max_socket_instances | -1 |
| socket | **/tmp/mysql_sandbox45007.sock** |
+-----------------------------------------+------------------------------+
3 rows in set (0.01 sec)
以下是一个例子：
mysql -uroot -pmsandbox -S /tmp/mysql_sandbox45007.sock
您的.env：
DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=landon_app
DB_USERNAME=landon_app
DB_PASSWORD=landon_app
DB_SOCKET=<socket>

您还需要为information_schema数据库添加权限：
GRANT ALL ON `information_schema`.* TO 'landon_app'@'localhost';
（后跟：FLUSH PRIVILEGES;申请更改。）
