无法在Heroku上迁移数据库（尝试过MySQL和PostgreSQL）

Question

I am trying to run Laravel app on Heroku

I've pushed the app and configured it. But when I am trying to migrate database via using command heroku run php artisan serve it is giving following error.

In Connection.php line 664:

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from information_s chema.tables where table_schema = forge and table_name = migrations)

In Connector.php line 68:

SQLSTATE[HY000] [2002] Connection refused

I've made changes in .env file too for DB credentials and host.

Answer 1

You need to set the environment variables in Heroku's web admin panel

Go to your app in Heroku -> settings -> Reveal Config Vars

Then set your environment variable Take for example

DB_DATABASE = your-database-name 
DB_HOST = your-database-host-name
DB_PASSWORD = your-db-password
DB_PORT = your-db-port
DB_USERNAME = your-db-username
