barntt77 commented on issue #809: Web server failed to start. Port 8080 was already in use. URL: https://github.com/apache/incubator-dolphinscheduler/issues/809#issuecomment-533378712 > ui端口占用可以在启动的时候指定端口 > 后端服务端口专业可以在conf下配置对应服务，server.port = 8081 ui端 nginx已重新设置端口，且可以正常启动 后端在conf下重新设置端口server.port = 7171， 但是问题在于 一个节点的master服务启动完后 半分钟就自动挂，日志显示8080端口被占用。 监控中心master只显示一台，我配了两台
