如何使用rake db:migrate用户对数据库postgres运行my_db。已创建角色postgres和my_db数据库，但是当尝试运行migration命令时，它将引发错误。如果缺少任何步骤，请通知我。我不想使用vagrant用户和vagrant database

vagrant@vagrant-ubuntu-trusty-64:/vagrant$ vagrant ssh
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ psql -h localhost -d my_db -U postgres
my_db=#\q
vagrant@vagrant-ubuntu-trusty-64:/vagrant$ rake db:migrate
vagrant@vagrant-ubuntu-trusty-64:/vagrant$rake db:migrate
rake aborted!
PG::ConnectionBad: FATAL:  database "vagrant" does not exist

您可以通过config/database.yml设置数据库配置。如果您要在两种环境（development和test）上都使用PG，它看起来可能像这样：

default: &default
  adapter: postgresql
  encoding: unicode
  host: localhost

development:
  <<: *default
  database: my_db
  username: postgres
  password: PASSWORD

test:
  <<: *default
  database: my_db_test
  username: postgres
  password: PASSWORD
