A valid cache entry key is required. Use getAll() to get all table data

Hi,

Can anyone assist me with installation? I have problem with this error:

[ec2-user@ip-10-0-0-232 opensocial]$ ./vendor/drush/drush/drush -y site-install social --db-url=mysql://root:root@127.0.0.1:3306/social

You are about to:
* CREATE the 'social' database.
// Do you want to continue?: yes.

[warning] Failed to drop or create the database. Do it yourself before installing. ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
