Access denied for user ‘homestead’@’localhost’ (using password: YES)

Reason of that error is using default params for database connection.

Probably You forgot to change values for database connection like DB_HOST, DB_DATABASE, DB_USERNAME, DB_PASSWORD inside .env file

if you done this but still have that error it means problem can be config was cached. To fix it, run:

php artisan config:clear

Try to reload (apache/nginx).

unix_socket problem

if you use

'unix_socket'   => '/var/run/mysqld/mysqld.sock',

for mysql connection, try to check that socket address is correct.

run:

mysql> show variables like '%sock%';
