我目前正在关注一个关于lynda的laravel / mysql教程，并按照以下步骤创建一个数据库并将其连接到我的laravel框架。
登录mysql时出现：
ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)
工具/原料
- Ubuntu18
- MySQL 8.0.14
方法/步骤
- 1命令行终端登录mysql时界面出现：ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)
- 2需要跳过密码验证进入mysql进行修改密码命令行终端输入：sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf在文本最后添加（如果不知道怎么添加，可以留言给我）skip-grant-tables保存退出
- 3重启服务service mysql stopservice mysql start
- 4再次登录mysql密码填自己安装时设置的密码，或者直接回车进入
- 5输入修改密码的命令发现出现错误提示：ERROR 1290 (HY000): The MySQL server is running with the –skip-grant-tables option so it cannot execute this statement
- 6命令行终端输入flush privileges;然后再次输入修改密码命令ALTER USER ‘root’@’localhost’ IDENTIFIED WITH mysql_native_password BY ‘root’;修改成功
- 7退出mysql重新进入mysql配置文件sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf将添加的skip-grant-tables删除然后保存退出
- 8重启服务service mysql restart登录mysql成功
以下步骤帮助命名我的数据库，更改我的用户名和密码（不再是用户：root，password：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';
这样做后，我可以在命令行上运行它：mysql -u -landon_app -plandon_app
并且mysql已启动并正在运行。
但问题是，在创建我的迁移并设置了表架构和所有内容之后，我收到一个错误消息
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，并让其他人遇到类似的事情？我想，因为命令行mysql -u -landon_app -plandon_app工作，应该没有问题php artisan migrate
编辑：config / database.php
