Hawtio port conflict issue

I am trying to execute the Hawtio-1.5.jar in Linux environment. When I am running the executable, it says port is already in use. Can you suggest how to change the port number in Hawtio jar file to resolve this issue? I cannot change the port number of 8080 which is already using by other my service.

Solution

  • You can change the port number by --port option:

    java -jar hawtio-app-1.5.2.jar --port 8090
