Question

我在本地Windows机器上设置了Apache Usergrid，但在启动时tomcat在日志中显示错误。因此，我们也无法访问usergrid应用程序。以下是参考的错误日志。谢谢！

看起来你没有使用Usergrid数据库＆amp;超级用户设置，如Deploying to Tomcat步骤中所述。

您可以使用http://dbeaver.jkiss.org访问C *，看看在执行这些步骤时，Usergrid是否能够成功设置键空间。

经过长时间的努力解决这个问题后，我意识到在我的情况下，弹性搜索1.7.6以及2.x在 / etc / default / elasticsearch 中没有额外配置时无法启动。只需在文件中添加此行 START_DAEMON = true ，然后重新启动elasticsearch就可以在Ubuntu 16.04上为我工作。

现在可以成功连接到设置用户网格。到处寻找答案，但到目前为止找不到任何参考。因此想发布。我正在使用的堆栈是 1. apache-usergrid-2.1.0 2. cassandra 3.7 3. tomcat8 4. elasticsearch 2.4.4

由于这个问题，我几乎放弃了使用usergrid。
