Preface

Everyone should know that when using the laravel framework to develop PHP programs, configuring the .env file of the framework is crucial. This file needs to configure the database, database user, cache, etc. Let’s take a look at the detailed configuration tutorial.

1. Configure APP_KEY

The laravel framework hardcodes the symmetric encryption key in the .envconfiguration file by default , the development environment and the production environment do not need to and should be strictly prohibited from using the same APP_KEY
Run php artisan key:generate in the project and the key will be automatically generated in the .env file.

2. Configure database and database user

(1)Create database

Use command mysql < init_db.sql Execute the script to create the database

(2) Create database user

Use the command mysql < create_usr.sqlExecute the script to create the user

Two users are created here, one cloudlab_dev user has Insert, Select,Delete,Update,CREATE permissions

A cloudlab_dba has Insert,Select,Delete,Update,ALTER,CREATE,DROP,INDEX,LOCK permissions.

Usually use the cloudlab_dev user, and use cloudlab_dba when creating tables

Result:

DB_HOST=127.0.0.1
DB_DATABASE=cloudlab
DB_USERNAME=cloudlab-dev
DB_PASSWORD=cloudla******

DB_USERNAME_DBA=cloudlab-dba
DB_PASSWORD_DBA=cloud*******
