昨天我安装了 Postgres 和 pgAdminIII,一切正常,但重新加载后它停止工作。在rails server
我收到错误消息后:
=> Booting Thin
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting
/home/home/.rvm/gems/ruby-1.9.3-p448/gems/activerecord-3.2.13/lib/active_record/connection_adapters/postgresql_adapter.rb:1216:in `initialize': could not connect to server: Connection refused (PG::ConnectionBad)
Is the server running on host "localhost" (127.0.0.1) and accepting
TCP/IP connections on port 5432?

Error: is not accessible or does not exist
我也不知道为什么,但现在rails server
把这个错误:
=> Booting Thin
=> Rails 3.2.13 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
