无法在Windows上运行Apache nifi

Question

在我目前的项目中，我一直在使用apache nifi进行一些实验目的。 当我第一次配置。 nifi运行完美（当我输入http://localhost:8080/nifi/时，我能够看到Google Chrome上的画布，工具栏）。但是，重启计算机一次后，我无法运行它。

当我键入nifi.0.7.0\bin\run-nifi.bat命令时，我在控制台上看到以下消息。

您能否告诉我这是什么问题？我怎么能解决这个问题？

和nifi-user.log是空。

当我尝试拨打localhost:8080/nifi/时，我看到以下内容。

Answer 1

尝试检查配置文件是否具有值“nifi.sensitive.props.key =”以下键“。 如果它是空的，请设置一个键，如示例“nifi.sensitive.props.key = 132134”。

如果您仍然处于烦恼状态，请观看此视频，应该有所帮助。 https://www.youtube.com/watch?v=DDd6KayUHt8

一切顺利。

Answer 2

除了之前的评论帮助我解决了这个问题之外，您还需要花费一点时间，因为这里已经讨论了https://community.hortonworks.com/questions/107192/nifi-web-ui-not-working-facing-error-err-connectio.html。事实上，在启动Nifi之后，Web界面并不能立即到达，Nifi需要一段时间来初始化所有内容。您可以通过访问名为：nifi-app.log的日志文件来追踪Nifi的执行情况，您可以在NIFI_HOME/logs中找到它。 我认为消息：org.apache.nifi.NiFi控制器初始化耗时132792678105纳秒（132秒）是Nifi Web界面可以使用的好兆头。
