mysql - QLSTATE[HY000] [2002] 连接被拒绝 (SQL: select * from inform)

问题描述

我收到一个错误：

SQLSTATE[HY000] [2002] 连接被拒绝（SQL: select * from information_schema.tables where table_schema = lar1 and table_name = migrations and table_type = 'BASE TABLE'）

当我用 localhost 替换 DB_HOST 时会出现错误

SQLSTATE[HY000] [2002] 没有这样的文件或目录（SQL：select * from information_schema.tables where table_schema = lar1 and table_name = migrations and table_type = 'BASE TABLE'）

如何解决？

这是我的代码：

APP_ENV=local

解决方案

在您的.env文件中，DB_HOST从更改127.0.0.1为localhost

接着

php artisan cache:clear
php artisan route:clear
php artisan config:clear
php artisan view:clear
