Question

尝试在neo4j with jruby和heroku上部署heroku logs应用程序会显示：

Neo4j has been shutdown using storage_path: /app/db/neo4j-production

App配置如下：

## config/application.rb 

    # Configure where the neo4j database should exist
      config.neo4j.storage_path = "#{config.root}/db/neo4j-#{Rails.env}"

任何想法可能出错？

1.for my heroku app我正在使用heroku neo4j addon

2.我用于回购的a sample neo4j rails app repo。

Answer 1

听起来你的路是错的。您当然知道Heroku不提供持久存储吗？但OpenShift确实如此。

在Heroku上，我会选择托管的GrapheneDB。然后，您可以使用neography或neo4j.rb（在服务器模式下）连接到您的neo4j数据库。
