不同主机上的 mesos slave 无法添加自身

Question

Mesos 从站无法将自己添加到集群中。现在我有 3 台机器，3 个从机运行，1 个主机运行。

但是在 mesos 页面上，我只能看到一个主设备和一个从设备(与当前主设备的主机相同)。我可以看到马拉松运行，应用程序等。
但只是其他从站无法连接到主站。

从日志::

zookeeer on master::

 ls /mesos
[info_0000000009, info_0000000010, log_replicas]
 ls /mesos/info_0000000009
[]

请注意从日志中的行:

Trying to get '/mesos/info_0000000009' in ZooKeeper

然后为什么从机假定主机为 127.0.1.1:5050 .. 我从未指定过

Leading master master@127.0.1.1:5050

但是动物园管理员回来了
ls/mesos/info_0000000009
[]

查看了master的zookeeper，发现它根本没有设置..不是mesos中的错误或者ki缺少一些配置..

此外，master 上的 zookeeper 登录关闭了客户端连接(可能现在客户端开始连接到其他一些 master)

注意:与主服务器在同一主机上的从服务器工作得很好。

现在试图解决它超过 2 天.. 请帮助..

对我来说看起来像一个错误..我在哪里可以看到 zookeeper 中的当前主人.. 是不是类似于/mesos/info_0000000009 ？但我得到了动物园管理员

ls/mesos/info_0000000009
[]

一个空数组 thr .. 这是正确的，因为从客户端日志中试图寻找这个:...

然后客户端尝试 127.0.1.1:5050

这是完整的从属日志:

Answer 1

"But at the mesos page i can see just one master and one slave (same as the master's host present)."

这很可能是因为主服务器无法与其他机器上的代理(又名从服务器)建立连接。现在(这可能会随着新的 HTTP API 而改变)，master 必须能够打开与代理的连接，这意味着代理必须在向 master 注册时报告非本地 IP。从您的日志看来，代理绑定(bind)到本地 IP ( 127.0.1.1) 。您可以通过 --ip 标志更改它。
