Why am I getting a SQLSTATE[HY000] [1045] Access denied error when setting up the database?

Answer: This indicates incorrect DB credentials. Verify DB_DATABASE, DB_USERNAME, DB_PASSWORD, and DB_HOST in your .env file, and ensure the user has privileges to access the database from your server.

Common Causes:

• Incorrect database credentials in .env file
• Database user doesn't exist
• Wrong password
• Database doesn't exist
• Host/port configuration issues
• User lacks proper privileges

Step-by-Step Solution:

1. Check your .env file:

   DB_CONNECTION=mysql
   DB_HOST=127.0.0.1
   DB_PORT=3306
   DB_DATABASE=taskify_db
   DB_USERNAME=your_username
   DB_PASSWORD=your_password

2. Verify database exists:

   mysql -u root -p -e "SHOW DATABASES;"

3. Create database if needed:

   mysql -u root -p -e "CREATE DATABASE taskify_db;"

4. Create database user:

   mysql -u root -p -e "CREATE USER 'taskify_user'@'localhost' IDENTIFIED BY 'your_password';"

5. Grant privileges:

   mysql -u root -p -e "GRANT ALL PRIVILEGES ON taskify_db.* TO 'taskify_user'@'localhost';"

6. Test connection:

   php artisan migrate:status

Testing Database Connection:

Use Laravel's tinker to test your database connection:

php artisan tinker
DB::connection()->getPdo();
