Question

当我尝试使用http://localhost:8080/nifi连接到Nifi UI时，出现错误

    org.apache.nifi.web.server.JettyServer Failed to start web server... shutting down.

任何人都可以提出此问题的原因吗？ Nifi版本1.9.2，安装在Windows计算机上

这是nifi状态日志，

Answer 1

nifi使用的端口已被另一个进程使用。
您可以在conf/nifi.properties

中更改Web服务器端口

Apache Nifi-拒绝连接到本地主机错误
