启动Mesos slave脚本时，要使用root权限。如果和Mesos Master运行在不同Server上，要指定所在机器的IP：
$ sudo ./bin/mesos-slave.sh --master=10.100.3.50:5050 --ip=10.100.3.39下文引自Building Applications on Mesos：
Since the slaves need to be able to launch containers and ensure that the executors are run as specific users, the slave process typically runs as root , so that it can create containers and run different executors as different users.
