10月 27 11:10:50 192.168.1.91 mesos-slave[25406]: To remedy this do as follows:
10月 27 11:10:50 192.168.1.91 mesos-slave[25406]: Step 1: rm -f /var/lib/mesos/meta/slaves/latest
10月 27 11:10:50 192.168.1.91 mesos-slave[25406]: This ensures agent doesn't recover old live executors.
10月 27 11:10:50 192.168.1.91 mesos-slave[25406]: Step 2: Restart the agent.

Is the docker daemon running?需要docker的守护进程，所以启动docker服务，然后
systemctl start docker.service
- 这样就可以启动成功了。
