I'm trying to get this question solve, 

To get mesos slave, is it we have to install Mesos and start mesos slave set up or?

And also I have problem with mesos master which I run a command 

`./bin/mesos-master.sh --ip=*** --work_dir=/var/lib/mesos`

end up it does not continue to run so i stop it running. End up I run the same above command and I get error shown

`Failed to initialize, bind: Address already in use [98]` 

Which part did I do wrongly?
