The above configuration sets up *remote* JMX management. JMX is always enabled, and you can connect from localhost (as the same user, or root) using tools like jvisualvm, etc. without specifying any of the stuff above. Note that enabling remote authentication with authentication disabled (and SSL disabled, too!) is pretty much a terrible idea: anyone can connect to your server and do all sorts of evil things. Of course, firewalls, etc. can be configured to restrict access, but it's generally a good idea to also restrict access via password and encrypt the traffic from the remote host to the server.
