rake db:migrate_plugins - rake aborted! \ Access denied for user 'root'@'localhost' (using password: NO)
For those receiving the error:
# rake db:migrate_plugins (in /var/www/vhosts/scatter3d.com/subdomains/redmine/httpdocs) Migrating engines... *rake aborted! Access denied for user 'root'@'localhost' (using password: NO)* (See full trace by running task with --trace)
It's not because your db.yml is setup wrong or you need to give root access to your DB. you simply just need to set the environment:
ake db:migrate_plugins RAILS_ENV=production
I'm thinking this may not be as obvious as the devs might think and could be added to the wiki.
