我试图在2台虚拟机上设置简单的mesos集群。 IP是：
我使用的是mesos 0.27.1（从Mesosphere下载的rpm）和CentOS Linux版本7.1.1503（Core）。
我成功部署了1个节点集群（10.10.0.102）：master和slave工作，我可以通过marathon部署和扩展一些简单的应用程序。
当我尝试在10.10.0.103上启动第二个从站时出现问题。总是，当我启动那个奴隶时，它的状态被停用。
10.10.0.103上的奴隶记录：

我尝试使用两种方法启动奴隶（在10.10.0.103上）：
两者都给我相同的结果。
另外在MESOS-SLAVE.WARNING中我也看到了：

基于类似主题，我看到这可能与网络配置有关，因此下面是一些有关以下内容的信息：
托管10.10.0.102上的文件
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.10.0.103 mesos2 mesos2.mydomain
10.10.0.102 mesos1 mesos1.mydomain
托管10.10.0.103上的文件
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
10.10.0.102 mesos1 mesos1.mydomain
10.10.0.103 mesos2 mesos2.mydomain
两个VM都有2个网络接口（没有环回）。以下来自10.10.0.103-在10.10.0.102上类似：

两个虚拟机都具有网络连接。

非常感谢所有帮助。

总是最简单的答案是最好的。结果我在slave节点上运行了iptables。禁用此功能可以解决我的问题：
systemctl disable firewalld
systemctl stop firewalld
谢谢大家的帮助！
