【问题描述】:
我想在 Cloud9 中为我的 rails 应用设置 postgresql。
尝试bundle exec rake db:create时出现以下错误。
could not connect to server: Connection refused
Is the server running on host "localhost" (::1) and accepting
TCP/IP connections on port 5432?
could not connect to server: Connection refused
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?
...
database.yml
default: &default
adapter: postgresql
encoding: unicode
pool: 5
username: <%= ENV['USERNAME'] %>
password: <%= ENV['PASSWORD'] %>
host: localhost
development:
<<: *default
database: app_development
test:
<<: *default
database: app_test
production:

database: app_production

gem 'pg', '~> 0.18.2'
/etc/postgresql/9.3/main/pg_hba.conf
# Database administrative login by Unix domain socket

虽然我在 stackoverflow 中发现了类似的问题,但它们对我不起作用。 如果您能建议我如何避免此错误,我们将不胜感激。
