新的问题
但是，当我们执行swarm时，仍然有问题
$ docker-machine ssh servm-1 "docker swarm init --advertise-addr 192.168.99.100"
Google出来的结果是Docker版本过低，还不能够swarm，我可是最新版本啊😂😂😂！
于是，我ssh进去，版本还真是低！！！居然是2015年的，我的天。
$ docker-machine ssh servm-1

Boot2Docker version 1.9.1, build master : cef800b - Fri Nov 20 19:33:59 UTC 2015
Docker version 1.9.1, build a34a1d5
此时发现，https://github.com/boot2docker/.../v1.9.1/boot2docker.iso，还真是1.9.1版本。
于是，下载了最新版本的boot2docker，并替换~/.docker/machine/cache/boot2docker.iso。
重新创建
$ docker-machine rm servm-1

$ docker-machine ssh servm-1 "docker swarm init --advertise-addr 192.168.99.102"
Swarm initialized: current node (nha5c34sqeptxxej52fezljkf) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-07kfvclhdq6rqpgjomjcsmfcjd8l9q576ety8tuzetbscyxfhk-5rvcpmvto7zz0bswjixlzbjb7 192.168.99.102:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
