ruby-on-rails - "We' 抱歉，但出了点问题。” Ubuntu 上的 Rails 应用程序、Apache 上、DigitalOcean 上的Passenger

Question

这是我第一次尝试在 Digitalocean 上部署 Rails 应用程序。我正在为我的 DBM 使用 Apache 服务器和 PostgreSQL。我已经有一个要用于我的应用程序的域。每当我尝试使用我得到的域访问我的网站时:

We're sorry, but something went wrong.

If you are the application owner check the logs for more information.

这些是我得到的日志。

我已经尝试了很多东西，但找不到问题所在。如果有人可以帮帮我，我将不胜感激!

我可以看到您遇到 PG 错误，您可以进行以下更改:

sudo nano /etc/postgresql/9.1/main/pg_hba.conf
 Change => local all all ident
 To => local all all trust
 if still do not work change to=> local all all md5
 Then restart your postgres server
 sudo /etc/init.d/postgresql restart
