我正在建立一个Mesos星团来演示。我的设置是一主两从。所有的机器都运行ubuntu14.04 lts并且在同一个本地网络上。我开始mesos硕士与命令根据文件。

./mesos-master.sh --ip=192.168.65.27 --work_dir=/var/lib/mesos

我可以启动并连接在另一台机器上运行的从机到主机

./mesos-slave.sh --master=192.168.65.27:5050

但是，每当我尝试将一个或多个从机连接到同一个主机时，只有最近连接的从机才会列在mesos的webui下 http://192.168.65.24:5050/#/slaves . 我检查了终端输出。对于一个奴隶来说，情况如下。
