Question

目前，我正在尝试在OpenShift上部署一个应用程序，该应用程序是在Rails 4和Ruby 2上开发的。

部署后，浏览器返回错误503.阅读完日志后...我什么都不懂！

Answer 1

成立;）

从互联网上的教程中复制/粘贴是错误的

在database.yml中

，它是

  adapter: postgresql
  encoding: utf8
  pool: 5
  database: <%=ENV['OPENSHIFT_APP_NAME']%>
  host: <%=ENV['$OPENSHIFT_POSTGRESQL_DB_HOST']%>
  port: <%=ENV['$OPENSHIFT_POSTGRESQL_DB_PORT']%>
  username: <%=ENV['OPENSHIFT_POSTGRESQL_DB_USERNAME']%>
  password: <%=ENV['OPENSHIFT_POSTGRESQL_DB_PASSWORD']%>

而不是

  adapter: postgresql
  encoding: utf8
  pool: 5
  database: <%=ENV['OPENSHIFT_APP_NAME']%>
  host: <%=ENV['OPENSHIFT_POSTGRESQL_DB_HOST']%>
  port: <%=ENV['OPENSHIFT_POSTGRESQL_DB_PORT']%>
  username: <%=ENV['OPENSHIFT_POSTGRESQL_DB_USERNAME']%>
  password: <%=ENV['OPENSHIFT_POSTGRESQL_DB_PASSWORD']%>

Answer 2

看起来Web和数据库服务器没有运行，或者根据当前配置无法定位。

我会寻找专注于OpenShift的教程或文章（如果不是在他们自己的文档和社区中 - 大多数主机都提供教程等）。

在部署rails之后，Openshift Error 503
