我做了一个rake db：在我的应用程序上使用postgres进行迁移.它访问被拒绝错误失败.

** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Invoke db:load_config (first_time)
** Invoke rails_env (first_time)
** Execute rails_env
** Execute db:load_config
** Execute db:migrate
rake aborted!
could not connect to server: Permission denied
    Is the server running locally and accepting
    connections on Unix domain socket "/var/pgsql_socket/.s.PGsql.5432"?

我检查了服务器是否正在运行,它运行正常.我可以使用成功连接到我的数据库

psql -Umyuser myapp_development
psql -Umyuser myapp_test

在创建一个新的PG用户时,它从来没有要求我输入密码,所以我没有给这个用户myuser的密码.

这是我的database.yml文件.

development:
  adapter: postgresql
  encoding: utf8
  database: myapp_development
  username: pgguy

test:
  adapter: postgresql
  encoding: utf8
  database: myapp_test
  username: pgguy

production:
  adapter: postgresql
  encoding: utf8
  database: myapp_production

我应该怎么做,从我的rails应用程序连接到它？

解决方法

development:
  adapter: postgresql
  encoding: utf8
  database: myapp_development
  username: myuser
  host: localhost

test:
  adapter: postgresql
  encoding: utf8
  database: myapp_test
  username: myuser
  host: localhost

production:
  adapter: postgresql
  encoding: utf8
  database: myapp_production
