无法启动Apache Usergrid

Question

我已经在本地windows机器上设置了Apache Usergrid，但是在启动时，tomcat在日志中显示错误。由于这个原因，我们也无法访问usergrid应用程序。下面是参考的错误日志。谢谢!

看起来您没有执行Deploying to Tomcat步骤中概述的Usergrid数据库和超级用户设置。

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

Answer 2

在与这个问题斗争了很长一段时间后，我意识到在我的例子中，如果没有/etc/default/elasticsearch.中的额外配置，elasticsearch 1.7.6和2.x就无法启动我在Ubuntu16.04上只需在文件中添加一行START_DAEMON=true并重新启动elasticsearch即可。

现在可以成功连接到设置usergrid。我到处寻找答案，但直到现在也找不到任何参考资料。因此，我想到了发布。我使用的堆栈是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。
