elasticsearch Kibana仪表板5601端口问题

我们在linux中使用端口5601设置kibana仪表板。突然，设置dsahboard不工作。我们找不到解决办法。因此，我们在kibana yml文件中将端口号5601更改为5602。重新启动服务器后，我可以打开仪表板。但我们需要运行5601端口，因为kibana dashboard映射到5601。你知道怎么解决这个问题吗

另一个任务似乎正在端口5601上运行。检查此特定端口上正在运行的程序，将其杀死，然后再次运行Kibana

您是否检查过是否有一个进程已经使用了端口5601？谢谢@MichaelDz。在终止另一个程序后。。它工作得和预期的一样好
