我正在建立一个 mesos 集群用于演示目的。我的设置是一个主人和两个奴隶。所有机器都在同一本地网络上运行 ubuntu 14.04 LTS。我正在按照文档使用命令启动 mesos master 。
./mesos-master.sh --ip=192.168.65.27 --work_dir=/var/lib/mesos
我可以启动并将在另一台机器上运行的从机连接到主机
./mesos-slave.sh --master=192.168.65.27:5050
但是，每当我尝试将另外一个从属连接到同一个主控时，只有最近连接的从属会在 mesos 的 webUI 下列出http://192.168.65.24:5050/#/slaves。我检查了终端输出。对于一个从站，它按如下方式进行。
